The embodiment of the application is applied to an optical communication system, which is a point-to-multipoint optical access network system, and the system generally consists of an optical line terminal (optical LINE TERMINAL, OLT), an optical distribution network (opticaldistributionnetwork, ODN) and an optical network terminal (optical network terminal, ONT). As shown in fig. 1, a plurality of ONT devices may be linked to the same OLT through an ODN.
With the popularization of fixed access broadband and the advent of various intelligent terminals, various emerging network services such as 4K/8K high definition video, virtual Reality (VR)/augmented reality (augmented reality, AR) technology, interactive games, home clouds, remote online education, online teleconferencing, remote medical treatment, etc. are emerging and gradually becoming an indispensable element of people's daily life. Provides great convenience for the work and life of the masses, and enriches the daily leisure and entertainment life of the people. In order to enjoy better network service experience, requirements of users on network quality such as broadband, time delay, reliability and the like are further improved. With the increasing demand for bandwidth and the increasing demand for access to business experience of families and small micro-enterprises, a point-to-multipoint network system for families and small micro-enterprises has been developed, and fiber-to-room (fibertotheroom, FTTR) technology has been proposed and paid a great deal of attention.
FTTR is that the optical fiber is further extended downwards to a room, and the WIFI access equipment is installed in the room, so that the distance between the user terminal equipment and the WIFI equipment is shortened, the quality of WIFI signals is ensured, and the problem of poor signals of the user terminal equipment caused by unstable WIFI access is solved. FTTR is shown in fig. 2, and includes a master gateway device, at least one optical splitter, and a plurality of slave gateway devices. The main gateway equipment is upwards connected with the OLT and can support gigabit home-entering; an optical fiber interface is provided downwards, and is connected with each slave gateway device (equivalent to an ONT) through an optical splitter (equivalent to an ODN). In the case of multi-level networking, a plurality of optical splitters are cascaded together, and the distance between each optical splitter and a master gateway device is represented as the topology level of that optical splitter and its connected slave gateway device. As shown in fig. 2, 4 optical splitters form a 4-stage cascade, each stage includes 8 slave gateway devices, the topology level of the optical splitter directly connected with the master gateway device is the first stage, and the topology level of the slave gateway device connected with the optical splitter is also the first stage; the topology level of the optical splitter furthest from the master gateway device is the fourth level, and similarly, the topology level of the slave gateway device connected with the optical splitter is the fourth level.
In the network environment, because the field construction environment of a small micro enterprise is complex and the capacity of operation and maintenance personnel of the enterprise is limited, the network is often required to provide rich operation and maintenance capacity and monitoring capacity, and the network connection state and which branch port of the optical splitter corresponding to the gateway can be explicitly presented, so that the operation and maintenance personnel can monitor and process the network condition timely, accurately and efficiently.
In order to achieve the above object, a first aspect of the present application provides a signal transmission method applied to the above optical communication system, which includes a master gateway device, a first optical splitter, and a plurality of slave gateway devices. It can be understood that in the optical network system of the first-level networking, the number of the optical splitters is one, and the optical splitter is a first optical splitter; in the optical network system of the multi-level networking, the number of the optical splitters is a plurality of, and the first optical splitter is one of the optical splitters.
The first optical splitter comprises a first port and a plurality of second ports, the first optical splitter is connected with the main gateway equipment through the first port, and the first optical splitter is connected with the plurality of auxiliary gateway equipment through the plurality of second ports in a one-to-one correspondence manner. It can be understood that the first port is a receiving port of an optical signal, and is configured to receive the optical signal sent by the main gateway device, where the optical signal may be directly sent by the main gateway device, or may be transferred to the first optical splitter through another optical splitter, that is, the first optical splitter may be directly connected to the main gateway device, or may be indirectly connected to the main gateway device. In an optical network system of multi-level networking, if a first optical splitter is directly connected with a main gateway device, the topology level of the first optical splitter in the optical network system is a first level; if other N optical splitters are further connected between the first optical splitter and the main gateway device, the topology level where the first optical splitter is located is n+1, where N is a natural number. The second port of the first optical splitter is an optical splitting port, the slave gateway device is connected to the second port, and the slave gateway device receives the optical splitting signal split by the first optical splitter through the second port.
For ease of understanding, referring to fig. 3, fig. 3 is a flowchart of a method for signaling according to an embodiment of the present application, where the method is performed by a first optical splitter, and includes:
301, configuring a plurality of corresponding first control signals for a plurality of second ports.
The first optical splitter includes a plurality of second ports, and in order to distinguish the plurality of second ports, a plurality of first control signals may be configured for the plurality of second ports, where the plurality of second ports and the plurality of first control signals are in a one-to-one correspondence, that is, the first control signals configured for each second port are different, different first control signals may have different frequencies and the same intensities, or the same frequencies and the same intensities, or different first control signals may have different change rules, and in any case, the plurality of second ports correspond to the plurality of first control signals, and the first control signals are located to the corresponding second ports.
The configuration of the first control signal may be configured by a control unit in the first optical splitter, for example, a micro control unit (microcontroller unit, MCU) is disposed in the first optical splitter, and various control signals with specific rules are generated by the MCU, and different control signals may have different intensities, different frequencies or different rules.
The first control signal is used for distinguishing each second port of the first optical splitter, so that the first control signal can be preconfigured, and the signal is directly loaded when needed, for example, an MCU or a complex programmable logic device (complex programmable logic device, CPLD) is preconfigured with programs for disturbing electrodes of different second ports; the first control signal may be configured after the second port is connected to the slave gateway device, for example, when the slave gateway device obtains the optical splitting signal from the second port, the first control signal is configured for the second port, in one possible implementation method, the second port is empty, and if the second port is not connected to the slave gateway device, the first control signal is not configured for the second port; the first control signal may be configured after a corresponding instruction is acquired, for example, when the first optical splitter receives a port detection instruction sent by the main gateway device or the slave gateway device, a plurality of first control signals are configured for a plurality of second ports. It can be understood that, according to the method provided by the embodiment of the present application, a person skilled in the art may set the configuration method and the configuration precondition of the first control signal according to the requirement.
302, Transmitting spectroscopic signals to a plurality of slave gateway devices;
it can be understood that after the first optical splitter receives the optical signal sent by the main gateway device through the first port, the first optical splitter sends the optical signal through each optical splitting port (i.e. the second port), and the sent signal is an optical splitting signal.
303 Applying corresponding first disturbance information to the spectroscopic signal based on the plurality of first control signals.
Since the first control signals are configured according to the second ports, different first disturbance information may be sent to the plurality of slave gateway devices through the plurality of second ports based on the plurality of first control signals. The first disturbance information is used for determining port information of a second port connected with the first optical splitter from the gateway equipment.
The port information determined by the gateway device may be a serial number of a port connected to the gateway device and the first optical splitter or a specified port identifier, taking a conventional optical splitter as an example, assuming that the conventional optical splitter has 8 optical splitting ports, marking the 8 optical splitting ports as No. 1 to No. 8 optical splitting ports, and respectively configuring a corresponding first control signal for each optical splitting port; after receiving the first disturbance information applied based on the first control signal from the gateway device, the gateway device can determine the serial number or the identifier of the optical splitting port according to the characteristics carried in the first disturbance information because the first disturbance information corresponds to the first control information and the first control information corresponds to the optical splitting port, thereby determining which optical splitting port of the optical splitter is connected with the gateway device, and achieving the effect of port identification. It should be understood that the slave gateway device should have the function of receiving and recording the first disturbance information and performing the port identification according to the feature of the first disturbance information, for example, the slave gateway device may be preconfigured with a lookup table, where the lookup table includes a mapping relationship between the feature of the first disturbance information and the port information, or the slave gateway device may perform the port identification according to other internal or external identification devices, for example, send the feature of the first disturbance information to a corresponding identification device, where the identification device includes the mapping relationship between the feature of the first disturbance information and the port information.
In one possible implementation method, the difference between the plurality of first disturbance information may be that the intensities of the disturbance signals are different, for example, the intensity of the first disturbance information sent out from the No. 1 spectroscopic port is the largest, the intensity of the first disturbance information sent out from the No. 8 spectroscopic port is the weakest, and the serial number of the second port connected with the gateway device is judged according to the intensity of the received first disturbance information; in another possible implementation method, the difference between the plurality of first disturbance information may be that the frequencies of the disturbance signals are different, for example, the frequency of the first disturbance information sent out from the No. 1 spectroscopic port is the highest, the frequency of the first disturbance information sent out from the No. 8 spectroscopic port is the lowest, and the serial number of the second port connected with the gateway device is determined according to the frequency of the received first disturbance information; in another possible implementation method, the distinction between the plurality of first disturbance information may be different between the sending rules of the disturbance signals, for example, the length rule or the on-off rule of the first disturbance signals sent by the 8 light splitting ports may correspond to 8 mousse codes or 8 numbers corresponding to binary, and the serial number of the second port connected with the gateway device is judged according to the rule of the received first disturbance information from the gateway device. The foregoing gives several possible forms of the first disturbance information, but in practical application, the method is not limited to the implementation in the foregoing several ways, and all the methods based on the first control signal, the second port, and other port identification implemented from the gateway device and the one-to-one correspondence between the first disturbance information are also within the scope of the present application.
It can be understood that after the port information is determined, the slave gateway device can store the port information, and when the operation and maintenance personnel performs corresponding trouble shooting, the port information can be called from the slave gateway device; the slave gateway device may also send the port information to the master gateway device, where the port information may be sent back to the master gateway device in a wired form through the optical splitter, or may be reported to the master gateway device in a wireless form, for example, the port information may be reported to the OLT through an optical network unit management control interface (ONU MANAGEMENT AND control interface, OMCI) message, and an operator confirms the connection state of each slave gateway device through a corresponding management module on the master gateway device; the slave gateway device can also upload the port information to a management terminal, the management terminal can be a handheld terminal device, the terminal device is used for network diagnosis, the connection state of each port of the optical splitter is displayed in a visual mode, and the operation and maintenance personnel acquire the connected port information of each slave gateway device through the management terminal.
According to the signal sending method provided by the embodiment of the application, different control signals are configured for different light splitting ports of the optical splitter, and disturbance is applied to the light splitting signals based on the control signals, so that the light splitting signals sent out from different light splitting ports can carry different disturbance information, and the slave gateway equipment can determine which port of the optical splitter is connected according to the received disturbance information because the disturbance information received from the gateway equipment connected with different ports is different. The operation and maintenance personnel can be positioned to the connection port from the gateway equipment, so that the processing efficiency of related network problems is improved.
Specifically, the first control signal may be an electrical signal, the electrical signal perturbs the optical splitting signal, and the electrical signal may be applied to the second port, so that the optical splitting signal sent by the second port is perturbed, that is, the optical splitting signal carries first perturbation information, where the first perturbation information is optical power perturbation information.
Specifically, because the optical splitter is used for dividing an optical signal received from the main gateway device into a plurality of optical splitting signals to be sent out, a carrier for transmitting the optical splitting signals is an optical fiber branch, and the optical fiber branch is wrapped with an outer cladding, one possible implementation method is that an induction cladding is arranged on the optical fiber branch, the induction cladding belongs to a part of the outer cladding, and is made of a thermo-optical material or an electro-optical material, when a first control signal is an electric signal, the first control signal can be loaded on the induction cladding of the optical fiber branch connected with a corresponding second port, the refractive index of the induction cladding changes, and light leaks, so that the optical splitting signals sent out from the second port are disturbed, and a corresponding first disturbance signal is formed. It will be appreciated that since the spectroscopic signal is an optical signal, the optical signal is subject to a power disturbance upon application of an electrical signal thereto, and thus the first disturbance signal at this time is in the form of a power disturbance signal. Furthermore, an independent induction cladding is arranged on each optical fiber branch, the control signal independently applies the disturbance signal to each light splitting signal, and the light splitting signals are not mutually interfered.
The first control signal may also be an electromagnetic signal that may be applied to the second port such that a disturbance occurs in the signal emitted by the second port.
In one possible implementation method, step 301 specifically includes: configuring a plurality of corresponding first control signals for a plurality of second ports according to a topology level of the first optical splitter in the optical communication system;
At this time, the first perturbation information is also used to determine its topology level in the optical communication system from the gateway device.
It will be appreciated that since the optical communication system may be in the form of a one-level networking or multi-level networking, multiple topology levels are included under the multi-level networking. The first optical splitter may configure the first control signal according to a topology level such that the first disturbance information is provided with topology level information, such as:
The first optical splitter can be set into different modes according to the topology level of the first optical splitter during installation, and disturbance information sent by a branching port of the first optical splitter is different in different modes. For example, the frequencies of the disturbance information sent by the optical splitters at different topology levels may be preset to be different or belong to different frequency ranges: setting the first optical splitter to a first mode if the first optical splitter is located at a first topology level, and setting the first optical splitter to a second mode if the first optical splitter is located at a second topology level; the frequency range of the disturbance information sent by the optical splitter at the first topological level is [ f1, f 2], the frequency range of the disturbance information sent by the optical splitter at the second topological level is [ f2, f 3), and the frequency range of the disturbance information sent by the optical splitter at the Nth topological level is [ fn, f (n+1)). From the frequency range of the received disturbance information, the gateway device can determine the topology level of itself in the optical network system.
The frequency of the disturbance information sent by the first optical splitter under different topology levels may be preset to be different, and the intensity of the disturbance information sent by different optical splitting ports may be different, for example: the disturbance intensity of the cascade port of each optical splitter can only penetrate through the first-stage optical splitter, namely, the slave gateway equipment at the third topology level can only sense the disturbance of the frequency f3, the slave gateway equipment at the second topology level can only sense the disturbance of the frequency f2, and the slave gateway equipment at the first topology level can only sense the disturbance of the frequency f 1. Three frequency corresponding levels are recorded in a register of the slave gateway equipment, the slave gateway equipment can distinguish the topology level where the slave gateway equipment is located by the frequency of the received disturbance information, and the spectroscopic port connected with the slave gateway equipment is determined by the intensity of the disturbance information.
In one possible implementation method, the optical communication system further includes a second optical splitter, the first port of the first optical splitter is connected to the second optical splitter, and the second optical splitter is connected to the main gateway device, that is, in the optical communication system, a topology level where the first optical splitter is located at a next stage of the second optical splitter, and an optical signal received by the first optical splitter from the first port is sent by the second optical splitter. It can be understood that the second optical splitter and the first optical splitter may be the same device, and the connection modes of the second optical splitter and the first optical splitter in the optical communication system are cascade connection, so that the second optical splitter may also send a second disturbance signal to other slave gateway devices connected with the second optical splitter for port identification from the gateway device, and the generation mode of the second disturbance information may be the same as or different from the generation mode of the first disturbance information by the first optical splitter.
In one case, the second optical splitter is similar to the first optical splitter, and may be set to different modes according to the topology level of the second optical splitter during installation, and the frequencies or frequency ranges of the disturbance information sent in the different modes are different, which is specifically referred to the related description of the first optical splitter and will not be repeated herein.
In another case, the method performed by the first optical splitter further includes:
and receiving a downlink optical signal sent by the second optical splitter, wherein the downlink optical signal carries second disturbance information.
Wherein the second perturbation information is used for a plurality of slave gateway devices to confirm a topology level of the second optical splitter in the optical communication system.
After the first optical splitter receives the downlink optical signal carrying the second disturbance information, the downlink optical signal is split into a plurality of optical splitting signals, the optical splitting signals are sent out from a plurality of second ports, and at the moment, the slave gateway equipment connected with the second ports also receives the second disturbance information.
The slave gateway device may further have a function of recording the second disturbance information and performing topology level identification according to characteristics of the second disturbance information when receiving the second disturbance information. For example, when the frequency ranges of the disturbance information sent by the optical splitters under different topology levels are different, after the first optical splitter receives the second disturbance information, the topology level of the second optical splitter can be judged according to the frequency range where the second disturbance information is located, and the topology level +1 is obtained, so that the own topology level is obtained.
It should be understood that the slave gateway device may also save its own topology level in the optical communication system after confirming it, which may be invoked from the gateway device when the service personnel performs a corresponding troubleshooting; the slave gateway equipment can also send the topology level to the master gateway equipment, and an operation and maintenance personnel confirms the connection state of each optical splitter through a corresponding management module on the master gateway equipment; the topology level can be uploaded to a management terminal from the gateway equipment, the management terminal can be a handheld terminal equipment, the terminal equipment is used for network diagnosis, the connection state of each port of the optical splitter is displayed in a visual mode, and an operation and maintenance person obtains the connection state of each optical splitter through the management terminal.
It can be appreciated that one possible implementation method is: the optical splitter at the first topological level sends disturbance information 1 with frequency f1, and after receiving the disturbance information 1, the optical splitter at the second topological level generates disturbance information with frequency f2 according to the frequency f 1. And so on until the optical splitter at the Nth topological level generates disturbance information with the frequency fn.
In one possible implementation method, the optical communication system further includes a third optical splitter; at this time, the first optical splitter includes a third port, and the third optical splitter is connected to the first optical splitter through the third port. In the optical communication system, the topology level of the third optical splitter is located at the next stage of the first optical splitter, and the first optical splitter transmits an optical signal sent by the main gateway device to the third optical splitter through the third port. It can be understood that the third optical splitter and the first optical splitter may be the same device, and the connection modes of the third optical splitter and the first optical splitter in the optical communication system are cascade connection, so that the third optical splitter may also send a disturbance signal for port identification to other slave gateway devices connected with the third optical splitter, similar to the first optical splitter and the second optical splitter, and a description of the disturbance signal sent by the third optical splitter is omitted here.
Under the above premise, the method performed by the first optical splitter may further include:
304, configuring a second control signal for the third port;
305, transmitting the cascade optical signal to a third optical splitter;
306, applying corresponding third disturbance information to the cascaded optical signal based on the second control signal. The third perturbation information is used for confirming the topology level of the first optical splitter in the optical communication system from the gateway equipment connected with the third optical splitter.
The first optical splitter may configure different control signals for the third port (cascade port) and the second port (drop port) so as to transmit different disturbance information, wherein the disturbance information transmitted through the cascade port is used for confirming a topology level of the first optical splitter in the optical communication system from the gateway device connected with the third optical splitter at a next topology level. It can be understood that the cascade optical signal sent by the first optical splitter is split by the third optical splitter, and the third optical splitter does not have a filtering function, so that the split signal still carries third disturbance information, the third disturbance information is transmitted to the slave gateway device connected with the third optical splitter, and the slave gateway device senses the topology level of the first optical splitter through the third disturbance information. After the topology level +1, the topology level to which the topology level belongs can be obtained.
It should be understood that, similar to the first optical splitter receiving the second disturbance information sent by the second optical splitter, the third optical splitter receiving the third disturbance information sent by the first optical splitter may have a function of recording the third disturbance information and performing topology level identification according to the characteristics of the third disturbance information, which is connected to the gateway device.
In one possible implementation method, step 303 specifically includes:
And randomly selecting a time period within a preset time range, and applying a plurality of corresponding first control signals to the plurality of second ports.
It will be appreciated that, in order to avoid interference conflicts between multiple optical splitters, each optical splitter may randomly select the frequency and duration of the disturbance within a certain time range, the start-stop time of the disturbance information may be recorded from the gateway device, and the disturbance information may not be identified in the time other than the time when the optical splitter connected thereto transmits the disturbance information.
According to the signal transmission method provided by the embodiment of the application, the optical splitter can configure corresponding control signals for different optical splitting ports, and then disturbance information is transmitted to the slave gateway equipment according to the control signals, so that the slave gateway equipment can recognize the optical splitting ports through the disturbance information, further, the optical splitters of different topology levels can transmit the disturbance information of different rules, the slave gateway equipment can recognize the topology level, the whole system is further assisted to realize the intellectualization of operation and maintenance management, and the capability of a user for operation and maintenance management network is improved. The method provided by the embodiment of the application can be realized by adding related hardware devices such as MCU or CPLD in the optical splitter, and the gateway device side does not need to be additionally provided with hardware setting, so that the realization is simple. In addition, the control signal can be applied to the port of the optical splitting port, only the material of the optical fiber jumper connector of the optical splitter is required to be changed, the connection mode between gateway equipment and the optical splitter is not required to be changed, the port identification can be realized through the existing optical fiber transmission, and the reliability is high.
The second aspect of the present application provides a port detection method applied to an optical communication system including a master gateway device, an optical splitter, and a plurality of slave gateway devices. It can be understood that in the optical network system of the first-level networking, the number of the optical splitters is one; in the optical network system of the multi-level networking, the number of the optical splitters is a plurality.
The optical splitter comprises a first port and a plurality of second ports, the optical splitter is connected with the main gateway equipment through the first port, and the optical splitter is connected with the plurality of auxiliary gateway equipment through the plurality of second ports in a one-to-one correspondence manner. In an optical network system of multi-level networking, if the optical splitter is directly connected with a main gateway device, the topology level of the optical splitter in the optical network system is a first level; if other N optical splitters are further connected between the optical splitter and the main gateway device, the topology level where the optical splitter is located is n+1, where N is a natural number. The second port of the optical splitter is an optical splitting port, the slave gateway device is connected with the optical splitting port, and the slave gateway device receives the split optical signal split by the optical splitter through the optical splitting port.
For ease of understanding, referring to fig. 4, fig. 4 is a flowchart of a method for port detection according to an embodiment of the present application, where the method is performed by a slave gateway device, and includes:
And 401, receiving a light splitting signal sent by an optical splitter, wherein the light splitting signal carries disturbance information, the disturbance information is generated based on a control signal, and the control signal is configured based on the light splitting port through the optical splitter.
The optical splitter includes a plurality of optical splitting ports, and in order to distinguish the plurality of optical splitting ports, a plurality of control signals may be configured for the plurality of optical splitting ports, where the plurality of control signals determine disturbance signals sent out from corresponding optical splitting ports, that is, a one-to-one correspondence relationship among the plurality of optical splitting ports, the plurality of control signals, and the plurality of disturbance signals. Information sent by the optical splitter is obtained from the gateway device from an optical splitting port of the optical splitter, wherein the information comprises the disturbance information.
402, Extracting disturbance information from the spectroscopic signal;
And after receiving the light splitting information, the gateway equipment senses disturbance of the light splitting information, so that disturbance information of a corresponding rule is extracted.
And 403, determining port information of a spectroscopic port connected with the optical splitter according to the disturbance information.
The port information determined by the gateway device may be a serial number of a port connected to the gateway device and the first optical splitter or a specified port identifier, taking a conventional optical splitter as an example, assuming that the conventional optical splitter has 8 optical splitting ports, marking the 8 optical splitting ports as No. 1 to No. 8 optical splitting ports, and respectively configuring a corresponding control signal for each optical splitting port; after receiving the disturbance information sent based on the control signal from the gateway device, the gateway device can determine the serial number or the identifier of the optical splitting port according to the characteristics carried in the disturbance information because the disturbance information corresponds to the control information and the control information corresponds to the optical splitting port, thereby determining which optical splitting port of the optical splitter is connected with the gateway device, and achieving the effect of port identification. It should be understood that the slave gateway device should have the function of receiving and recording the disturbance information and performing the port identification according to the feature of the disturbance information, for example, the slave gateway device may be preconfigured with a lookup table, where the lookup table includes the mapping relationship between the feature of the disturbance information and the port information, or the slave gateway device may perform the port identification according to other internal or external identification devices, for example, send the feature of the disturbance information to the corresponding identification device, where the identification device includes the mapping relationship between the feature of the disturbance information and the port information.
In one possible implementation method, the difference between the plurality of disturbance information may be that the intensities of the disturbance signals are different, for example, the intensity of the disturbance information sent out from the No. 1 spectroscopic port is the largest, the intensity of the disturbance information sent out from the No. 8 spectroscopic port is the weakest, and the serial number of the spectroscopic port connected with the gateway device is judged according to the intensity of the received disturbance information; in another possible implementation method, the difference between the multiple disturbance information may be that the frequencies of the disturbance signals are different, for example, the frequency of the disturbance information sent out from the No. 1 spectroscopic port is the highest, the frequency of the disturbance information sent out from the No. 8 spectroscopic port is the lowest, and the serial number of the spectroscopic port connected with the gateway device is determined by the frequency of the received disturbance information; in another possible implementation method, the distinction between the plurality of disturbance information may be different between the sending rules of the disturbance signals, for example, the length rule or the on-off rule of the disturbance signals sent by the 8 spectroscopic ports may correspond to 8 mousse codes or 8 numbers corresponding to binary, and the serial numbers of the spectroscopic ports connected with the gateway device are judged according to the received rule of the disturbance information. The foregoing gives several possible forms of disturbance information, but in practical application, the method is not limited to the above-mentioned forms, and all methods based on control signals, spectroscopic ports, and other port identification implemented from the one-to-one correspondence between gateway device and disturbance information are also within the scope of the present application.
In one possible implementation method, the control signal is an electrical signal, and the electrical signal is loaded on the optical splitting port, so that the optical splitting signal sent out from the optical splitting port is disturbed, and disturbance information is carried in the optical splitting signal, and the disturbance signal is in the form of a power disturbance signal. Thus, in step 402, the slave gateway device may extract the disturbance information by detecting the change rule of the optical power of the spectroscopic signal.
It will be appreciated that the primary gateway device sends an optical signal to the optical splitter, and the optical splitter sends the optical signal through each optical splitting port (i.e., the second port), where the sent signal is an optical splitting signal. After the optical splitter is configured with the corresponding control signal on the optical splitting port, when the control signal is an electrical signal, the control signal can be loaded on the corresponding optical splitting port, so that the signal emitted from the optical splitting port is disturbed, and a corresponding disturbance signal is formed.
In one possible implementation method, the method further includes:
a topology level in the optical communication system from the gateway device is determined based on the perturbation information 404.
It will be appreciated that the optical communication system may include a plurality of cascaded optical splitters, where each optical splitter corresponds to one topology level, so that there may be a difference between the disturbance information sent by the optical splitters in each topology level, for example, the frequency of the disturbance information sent by the optical splitters in different topology levels may be preset to be different or belong to different frequency ranges, for example, the frequency range of the disturbance information sent by the optical splitter in the first topology level is [ f1, f2 ], the frequency range of the disturbance information sent by the optical splitter in the second topology level is [ f2, f 3), and the frequency range of the disturbance information sent by the optical splitter in the nth topology level is [ fn, f (n+1)). From the frequency range of the received disturbance information, the gateway device can determine the topology level of itself in the optical network system. The frequencies of the disturbance information sent by the optical splitters under different topology levels can be preset to be different, namely, the slave gateway equipment can distinguish the topology level where the slave gateway equipment is located through the frequency of the received disturbance information, and the light splitting port connected with the slave gateway equipment can be determined according to the intensity of the disturbance information, for example, the disturbance intensity of the cascade port of each optical splitter can only penetrate the first-stage optical splitter, namely, the slave gateway equipment at the third topology level can only sense the disturbance of the frequency f3, the slave gateway equipment at the second topology level can only sense the disturbance of the frequency f2, and the slave gateway equipment at the first topology level can only sense the disturbance of the frequency f1, wherein three frequency corresponding levels are recorded in the register of the slave gateway equipment.
In another possible implementation method, a relationship mapping table is configured from the gateway device, and the relationship mapping table records the mapping relationship between disturbance information and the spectroscopic port; the step 402 specifically includes:
and determining port information of a splitting port connected with the optical splitter according to the disturbance information and the relation mapping table.
In the implementation method, the slave gateway device is preconfigured with a relation mapping table, and the relation mapping table specifically can comprise a mapping relation between the feature of disturbance information and the port serial number of the spectroscopic port. After receiving the disturbance information from the gateway equipment, the change of the disturbance intensity or the disturbance frequency of the disturbance information is recorded, and the branch port from which the disturbance information is sent can be identified through a table look-up form, so that the port identification is realized.
Based on the implementation method, the relation mapping table also records the mapping relation between disturbance information and topology level; correspondingly, the method executed by the gateway device further comprises:
based on the perturbation information and the relationship mapping table, a topology level of the slave gateway device in the optical communication system is determined 404.
For example, the frequencies of the disturbance information sent out by each optical splitting port of the optical splitter are different, but the disturbance information in different frequency ranges represents different topology levels, namely: based on the relation mapping table, receiving disturbance information with the frequency range of [ f1, f 2) to indicate that the slave gateway equipment is at a first topology level; the received disturbance information with frequency range [ f2, f3 ] indicates that the slave gateway device is at the second topology level, and the received disturbance information with frequency range [ fn, f (n+1)) indicates that the slave gateway device is at the nth topology level. For another example, the frequencies of the disturbance information sent by the optical splitter under different topology levels are different, the intensities of the disturbance information sent by different optical splitting ports are different, that is, the topology level where the slave gateway device is located can be distinguished by the frequency of the received disturbance information, and the optical splitting port connected with the slave gateway device is determined by the intensity of the disturbance information, that is: the disturbance intensity of the cascade port of each optical splitter can only penetrate through the first-stage optical splitter, the slave gateway equipment at the third topology level can only sense the disturbance of the frequency f3, the slave gateway equipment at the second topology level can only sense the disturbance of the frequency f2, the slave gateway equipment at the first topology level can only sense the disturbance of the frequency f1, and three frequency corresponding levels are recorded in the register of the slave gateway equipment.
Optionally, after determining the port information and/or the topology level, the slave gateway may save the port information and/or the topology level, and when the operation and maintenance personnel performs corresponding trouble shooting, the port information and/or the topology level may be called from the gateway device; the slave gateway device may also send the port information and/or the topology level to the master gateway device, where the port information and/or the topology level may be transmitted back to the master gateway device in a wired form through the optical splitter, or may be reported to the master gateway device in a wireless form, for example, a message is reported to the OLT through an optical network unit management control interface (ONU MANAGEMENT AND control interface, OMCI), and an operator confirms the connection state of each slave gateway device through a corresponding management module on the master gateway device; the port information and/or topology level may also be uploaded from the gateway device to a management terminal, which may be a handheld terminal device, where the terminal device is used for network diagnosis, and the connection state of each optical splitter, i.e. each port, of each stage is displayed in a visual form, and the operation and maintenance personnel obtains the connected port information and/or topology level of each slave gateway device through the management terminal.
The third aspect of the present application provides an optical splitter, where the optical splitter includes a first port and a plurality of second ports, and the optical splitter is connected to a master gateway device through the first port, and is connected to a plurality of slave gateway devices through a plurality of second ports in one-to-one correspondence, that is, the first port is a receiving port of an optical signal, and is configured to receive the optical signal sent by the master gateway device; the second port is a splitting port, and the splitting signal split by the optical splitter is received from the gateway device through the second port when the gateway device is connected with the second port.
Referring to fig. 5, fig. 5 is a schematic structural diagram of an optical splitter according to an embodiment of the present application, including:
The control module 501 is configured to configure a plurality of corresponding first control signals for a plurality of second ports.
It is understood that the control module 501 may be an MCU, and the MCU is configured to generate various control signals with specific rules, where different control signals may have different intensities, different frequencies, or different rules. The first control signal is used for distinguishing each second port of the optical splitter, so that the first control signal can be preconfigured, and the signal is directly loaded when needed, for example, the MCU or the CPLD presets programs for disturbing different second port electrodes.
A beam splitting module 502, configured to send beam splitting signals to a plurality of slave gateway devices;
a perturbation module 503, configured to apply corresponding first perturbation information to the spectroscopic signal based on the plurality of first control signals.
The first disturbance information is used for determining port information of a second port connected with the optical splitter from the gateway device.
The port information determined by the slave gateway device may be a serial number or a predetermined port identifier of a port to which the slave gateway device and the optical splitter are connected. After receiving the first disturbance information applied based on the first control signal from the gateway device, the gateway device can determine the serial number or the identifier of the optical splitting port according to the characteristics carried in the first disturbance information because the first disturbance information corresponds to the first control information and the first control information corresponds to the optical splitting port, thereby determining which optical splitting port of the optical splitter is connected with the gateway device, and achieving the effect of port identification.
In one possible implementation method, the difference between the plurality of first disturbance information may be that the intensities of the disturbance signals are different, and the serial number of the second port connected with the gateway device is judged according to the intensity of the received first disturbance information; in another possible implementation method, the difference between the plurality of first disturbance information may be that the frequencies of the disturbance signals are different, and the serial number of the second port connected with the gateway device is judged by the received frequency of the first disturbance information; in another possible implementation method, the distinction between the plurality of first disturbance information may be that the sending rule of the disturbance signal is different, and the sequence number of the second port connected with the gateway device is judged according to the received rule of the first disturbance information from the gateway device.
In one possible implementation, the first control signal is an electrical signal and the first disturbance information is optical power disturbance information.
Specifically, the first control signal may be an electrical signal, where the electrical signal perturbs the optical splitting signal, so that the optical splitting signal sent by the second port is perturbed, that is, the optical splitting signal carries first perturbation information, where the first perturbation information is optical power perturbation information.
It can be understood that, because the optical splitter is used to split the optical signal received from the main gateway device into a plurality of optical signals to be sent, the carrier for transmitting the optical signals is an optical fiber branch, the optical fiber branch is wrapped with an outer cladding, and one possible implementation method is to set an induction cladding on the optical fiber branch, where the induction cladding is a part of the outer cladding, and the induction cladding is made of a thermo-optical material or an electro-optical material, when the first control signal is an electrical signal, the first control signal can be loaded on the induction cladding of the optical fiber branch connected to the corresponding second port, the refractive index of the induction cladding changes, and light leaks, so that the optical signals sent from the second port are disturbed, and the corresponding first disturbance signal is formed. It will be appreciated that since the spectroscopic signal is an optical signal, the optical signal is subject to a power disturbance upon application of an electrical signal thereto, and thus the first disturbance signal at this time is in the form of a power disturbance signal. Furthermore, an independent induction cladding is arranged on each optical fiber branch, the control signal independently applies the disturbance signal to each light splitting signal, and the light splitting signals are not mutually interfered.
The first control signal may also be an electromagnetic signal that may be applied to the second port such that a disturbance occurs in the signal emitted by the second port.
That is, the perturbation module 503 is specifically configured to apply the corresponding plurality of first control signals to the inductive cladding of the corresponding optical fiber branches of the plurality of second ports.
In one possible implementation method, the control module 501 is specifically configured to configure a plurality of first control signals corresponding to a plurality of second ports according to a topology level of the optical splitter in the optical communication system; at this time, the first perturbation information is also used to determine the topology level from the gateway device.
It will be appreciated that since the optical communication system may be in the form of a one-level networking or multi-level networking, multiple topology levels are included under the multi-level networking. The optical splitter may configure the first control signal according to a topology level such that the first disturbance information is provided with topology level information, such as:
In case 1.1, the optical splitter may be set to different modes according to the topology level where it is located during installation, and in the different modes, the disturbance information sent by the branching ports of the optical splitter is different. For example, the frequencies of the disturbance information sent by the optical splitters at different topology levels may be preset to be different or belong to different frequency ranges: setting the optical splitter to a first mode if the optical splitter is located at a first topology level, and setting the optical splitter to a second mode if the optical splitter is located at a second topology level; the frequency range of the disturbance information sent by the optical splitter at the first topological level is [ f1, f2 ], the frequency range of the disturbance information sent by the optical splitter at the second topological level is [ f2, f 3), and the frequency range of the disturbance information sent by the optical splitter at the Nth topological level is [ fn, f (n+1)). From the frequency range of the received disturbance information, the gateway device can determine the topology level of itself in the optical network system.
In case 1.2, the frequencies of the disturbance information sent by the optical splitters under different topology levels may be preset, the intensities of the disturbance information sent by the optical splitters through different optical splitting ports may be different, for example, the disturbance intensity of the cascade port of each optical splitter may only penetrate through the first-stage optical splitter, that is, the slave gateway device at the third topology level may only sense the disturbance of the frequency f3, the slave gateway device at the second topology level may only sense the disturbance of the frequency f2, the slave gateway device at the first topology level may only sense the disturbance of the frequency f1, where three frequency corresponding levels are recorded in the register of the slave gateway device, the slave gateway device may distinguish the topology level where itself is located through the frequency of the received disturbance information, and the optical splitting port connected with the slave gateway device may be determined through the intensity of the disturbance information.
In case 2, the topology level may be obtained from the received disturbance information, i.e. the optical splitter further comprises:
the receiving module 504 is configured to receive a downlink optical signal sent by the second optical splitter, where the downlink optical signal carries second disturbance information;
The second perturbation information is used by the plurality of slave gateway devices to confirm the topology level of the second optical splitter in the optical communication system.
It will be appreciated that since the first port belongs to the signal receiving port, the second disturbance information is received by the first port. The second disturbance information can be sent through the main gateway device or through the optical splitter of the last topology level, and the embodiment of the application does not limit the source of the second disturbance information. If the second disturbance information is sent by the optical splitter of the previous topology level, the generation mode of the second disturbance information may be the same as the generation mode of the first disturbance information.
In one possible implementation, the optical splitter further includes a third port, and the third port is connected to the optical splitter of the next topology level. At this time:
The control module 501 is further configured to configure a second control signal for the third port;
The optical splitting module 502 is further configured to send a cascaded optical signal to the third optical splitter.
The perturbation module 503 is further configured to apply corresponding third perturbation information to the cascaded optical signal based on the second control signal; the second disturbance information is used for confirming the topology level of the first optical splitter with the slave gateway equipment of the third optical splitter.
In one possible implementation, the optical splitting module 502 is further configured to send the topology level to the primary gateway device.
It should be understood that after the slave gateway device confirms its own topology level in the optical communication system, the topology level may be sent to the master gateway device, and the operation and maintenance personnel confirms the connection state of each optical splitter through the corresponding management module on the master gateway device.
In one possible implementation method, the optical splitting module 502 is specifically configured to randomly select a time period within a preset time range and apply a plurality of corresponding first control signals to a plurality of second ports.
It will be appreciated that, in order to avoid interference conflicts between multiple optical splitters, each optical splitter may randomly select the frequency and duration of the disturbance within a certain time range, the start-stop time of the disturbance information may be recorded from the gateway device, and the disturbance information may not be identified in the time other than the time when the optical splitter connected thereto transmits the disturbance information.
A fourth aspect of the present application provides a slave gateway device applied to an optical communication system including a master gateway device, an optical splitter, and a plurality of slave gateway devices. It can be understood that in the optical network system of the first-level networking, the number of the optical splitters is one; in the optical network system of the multi-level networking, the number of the optical splitters is a plurality.
The optical splitter comprises an optical signal access port and an optical splitting port, wherein the optical signal access port is a port for receiving an optical signal sent by the main gateway equipment; the optical signal is split into a plurality of split signals after passing through the optical splitter, and the split signals are transmitted to the slave gateway device through the split ports, and for convenience of understanding, the optical signal access port will be hereinafter referred to as a first port, and the split port will be referred to as a second port. The optical splitter is connected with the main gateway equipment through a first port, and is connected with the plurality of auxiliary gateway equipment through a plurality of second ports in a one-to-one correspondence manner. In an optical network system of multi-level networking, if the optical splitter is directly connected with a main gateway device, the topology level of the optical splitter in the optical network system is a first level; if other N optical splitters are further connected between the optical splitter and the main gateway device, the topology level where the optical splitter is located is n+1, where N is a natural number. The second port of the optical splitter is an optical splitting port, the slave gateway device is connected with the second port, and the slave gateway device receives the split optical signal split by the optical splitter through the second port.
Referring to fig. 6, fig. 6 is a schematic structural diagram of a slave gateway device according to an embodiment of the present application, including:
A receiving module 601, configured to receive a split optical signal sent by the optical splitter, where the split optical signal carries disturbance information; the disturbance information is generated based on a control signal, and the control signal is configured based on the spectroscopic port through the optical splitter.
The extracting module 602 is configured to extract disturbance information from the spectroscopic signal.
An identification module 603, configured to determine port information of a drop port connected to the optical splitter according to the disturbance information;
The optical splitter includes a plurality of optical splitting ports, and in order to distinguish the plurality of optical splitting ports, a plurality of control signals may be configured for the plurality of optical splitting ports, where the plurality of control signals determine disturbance signals sent out from corresponding optical splitting ports, that is, a one-to-one correspondence relationship among the plurality of optical splitting ports, the plurality of control signals, and the plurality of disturbance signals. Information sent by the optical splitter is obtained from the gateway device from an optical splitting port of the optical splitter, wherein the information comprises the disturbance information.
The port information determined by the slave gateway device may be a serial number of a port connected to the slave gateway device and the optical splitter or a specified port identifier; after receiving the disturbance information sent based on the control signal from the gateway device, the gateway device can determine the serial number or the identifier of the optical splitting port according to the characteristics carried in the disturbance information because the disturbance information corresponds to the control information and the control information corresponds to the optical splitting port, thereby determining which optical splitting port of the optical splitter is connected with the gateway device, and achieving the effect of port identification.
In one possible implementation method, the control signal is an electrical signal, and the electrical signal is loaded on the optical splitting port, so that the optical splitting signal sent out from the optical splitting port is disturbed, and disturbance information is carried in the optical splitting signal, and the disturbance signal is in the form of a power disturbance signal. The slave gateway device can extract disturbance information by detecting the change rule of the optical power of the spectroscopic signal.
It will be appreciated that the primary gateway device sends an optical signal to the optical splitter, and the optical splitter sends the optical signal through each optical splitting port (i.e., the second port), where the sent signal is an optical splitting signal. After the optical splitter is configured with the corresponding control signal on the optical splitting port, when the control signal is an electrical signal, the control signal can be loaded on the corresponding optical splitting port, so that the signal emitted from the optical splitting port is disturbed, and a corresponding disturbance signal is formed.
In one possible implementation, the identification module 603 is further configured to determine a topology level in the optical communication system according to the perturbation information.
It will be appreciated that the optical communication system may include a plurality of cascaded optical splitters, where each optical splitter corresponds to one topology level, so that there may be a difference between the disturbance information sent by the optical splitters in each topology level, for example, the frequency of the disturbance information sent by the optical splitters in different topology levels may be preset to be different or belong to different frequency ranges, for example, the frequency range of the disturbance information sent by the optical splitter in the first topology level is [ f1, f2 ], the frequency range of the disturbance information sent by the optical splitter in the second topology level is [ f2, f 3), and the frequency range of the disturbance information sent by the optical splitter in the nth topology level is [ fn, f (n+1)). From the frequency range of the received disturbance information, the gateway device can determine the topology level of itself in the optical network system. The frequencies of the disturbance information sent by the optical splitters under different topology levels can be preset to be different, namely, the slave gateway equipment can distinguish the topology level where the slave gateway equipment is located through the frequency of the received disturbance information, and the light splitting port connected with the slave gateway equipment can be determined according to the intensity of the disturbance information, for example, the disturbance intensity of the cascade port of each optical splitter can only penetrate the first-stage optical splitter, namely, the slave gateway equipment at the third topology level can only sense the disturbance of the frequency f3, the slave gateway equipment at the second topology level can only sense the disturbance of the frequency f2, and the slave gateway equipment at the first topology level can only sense the disturbance of the frequency f1, wherein three frequency corresponding levels are recorded in the register of the slave gateway equipment.
In another possible implementation method, a relationship mapping table is configured from the gateway device, and the relationship mapping table records the mapping relationship between disturbance information and the spectroscopic port; at this time, the identifying module 603 is specifically configured to determine port information of the optical splitting port connected to the optical splitter according to the disturbance information and the relationship mapping table.
In the implementation method, the slave gateway device is preconfigured with a relation mapping table, and the relation mapping table specifically can comprise a mapping relation between the feature of disturbance information and the port serial number of the spectroscopic port. After receiving the disturbance information from the gateway equipment, the change of the disturbance intensity or the disturbance frequency of the disturbance information is recorded, and the branch port from which the disturbance information is sent can be identified through a table look-up form, so that the port identification is realized.
Based on the implementation method, the relation mapping table also records the mapping relation between disturbance information and topology level; at this time, the identifying module 603 is further configured to determine a topology level of the slave gateway device in the optical communication system according to the perturbation information and the relationship mapping table.
For example, the frequencies of the disturbance information sent out by each optical splitting port of the optical splitter are different, but the disturbance information in different frequency ranges represents different topology levels, namely: based on the relation mapping table, receiving disturbance information with the frequency range of [ f1, f 2) to indicate that the slave gateway equipment is at a topology level; the received disturbance information with frequency range [ f2, f3 ] indicates that the slave gateway device is at the second topology level, and the received disturbance information with frequency range [ fn, f (n+1)) indicates that the slave gateway device is at the nth topology level. For another example, the frequencies of the disturbance information sent by the optical splitter under different topology levels are different, the intensities of the disturbance information sent by different optical splitting ports are different, that is, the topology level where the slave gateway device is located can be distinguished by the frequency of the received disturbance information, and the optical splitting port connected with the slave gateway device is determined by the intensity of the disturbance information, that is: the disturbance intensity of the cascade port of each optical splitter can only penetrate through the first-stage optical splitter, the slave gateway equipment at the third topology level can only sense the disturbance of the frequency f3, the slave gateway equipment at the second topology level can only sense the disturbance of the frequency f2, the slave gateway equipment at the first topology level can only sense the disturbance of the frequency f1, and three frequency corresponding levels are recorded in the register of the slave gateway equipment.
Optionally, after determining the port information and/or the topology level from the gateway device, the gateway device may further include a storage module, configured to store the port information and/or the topology level, and when the operation and maintenance personnel performs corresponding troubleshooting, may call the port information and/or the topology level from the gateway device; the system also comprises a sending module, a master gateway device and an operation and maintenance personnel, wherein the sending module is used for sending port information and/or a topology level to the master gateway device, the port information and/or the topology level can be transmitted back to the master gateway device in a wired mode through an optical splitter, and can be reported to the master gateway device in a wireless mode, for example, an optical network unit management control interface (ONU MANAGEMENT AND control interface, OMCI) message is reported to the OLT, and the operation and maintenance personnel confirms the connection state of each slave gateway device through a corresponding management module on the master gateway device; the sending module may be further configured to upload the port information and/or the topology level to a management terminal, where the management terminal may be a handheld terminal device, where the terminal device is configured to display, in a visual form, a connection state of each port of the optical splitter of each stage, and an operation and maintenance personnel obtains, through the management terminal, the port information and/or the topology level connected to each slave gateway device.
