Detailed Description
In order to make the technical solutions of the embodiments of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without any creative efforts shall fall within the protection scope of the embodiments of the present invention.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of embodiments of the present invention and the above-described drawings, are intended to cover non-exclusive inclusions, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Referring to fig. 1, an embodiment of the present invention provides a communication method for low optical power down-regulation of a signal, including:
Whether the communication quality of the current low-speed data is poor or not can be identified by judging whether the continuous error reporting times of the check code exceed a preset threshold value or not, and if the communication quality is poor, the communication quality improvement requirement is indicated.
Whether the current state of the high-speed main data channel is in an effective state or an invalid state can be identified by judging whether the received optical power is lower than the conventional sensitivity, receiving the SD/L OS loss report information and/or receiving the system high bit error rate feedback information.
Since the modulation depth of the low-speed overhead data is increased or the modulation rate of the low-speed overhead data is reduced when the high-speed main data channel is in an effective state, which may cause the low-speed overhead data to interfere with the main data on the high-speed main data channel, this embodiment may continue to perform subsequent parameter adjustment operations when it is recognized that the communication quality of the current low-speed overhead data is poor and the high-speed main data channel is in an invalid state.
It should be noted that, in order to improve the processing efficiency, it is preferable to first determine whether the number of consecutive error reports of the check code in the low-speed overhead data exceeds a preset threshold, and if so, further determine other conditions.
And 102, the first optical module transmits low-speed top-adjusting data carrying parameter adjustment notification to a second optical module at an opposite end through a first low-speed top-adjusting transmitter at the local end.
And the parameter adjustment notification is used for notifying that the current received optical power of the second optical module is lower than the conventional sensitivity and the high error code of the low-speed ceiling-adjusting channel, and the modulation parameter needs to be adjusted so as to improve the communication quality of the low-speed ceiling-adjusting signal.
At this time, the first low-speed set-top transmitter transmits the low-speed set-top data according to the normal modulation parameters.
And 103, after obtaining the parameter adjustment notification, the second optical module adjusts the modulation parameter of the second low-speed top-modulation transmitter at the local terminal, and controls the second low-speed top-modulation transmitter to transmit the low-speed top-modulation data to the first optical module according to the adjusted modulation parameter, so as to improve the communication quality of the low-speed top-modulation data.
Specifically, the adjustment manner of the modulation parameter may include: increasing the modulation depth, for example from 5% to 25% (specifically increasing the peaking modulation current by a factor of 5); and/or, the modulation rate is reduced, e.g., from 10kbps to 2 kbps. In practical application, the specific adjustment mode and adjustment amplitude can be flexibly adjusted according to practical requirements, and the invention is not limited.
In this embodiment, since the high-speed main data channel is in an invalid state, neither the adjustment operation of increasing the modulation depth nor the adjustment operation of decreasing the modulation rate will interfere with the main data, thereby effectively improving the communication quality of the uplink or downlink low-speed data without interfering with the main data.
Example two
Referring to fig. 2, the second embodiment provides another communication method for a low optical power downlink control signal, which can simultaneously improve the communication quality of uplink and downlink low speed control data, and includes the steps of:
And 203, the first optical module transmits the low-speed ceiling-adjusting data carrying the parameter adjustment notice to the second optical module at the opposite end through the first low-speed ceiling-adjusting transmitter.
And 204, after obtaining the parameter adjustment notice, the second optical module adjusts the modulation parameter of the second low-speed top-modulation transmitter at the local terminal, and controls the second low-speed top-modulation transmitter to transmit the low-speed top-modulation data to the first optical module according to the adjusted modulation parameter.
Therefore, the first optical module and the second optical module which are respectively positioned at the local end or the far end can adjust the working parameters of the local low-speed ceiling-adjusting transmitter when the high-speed main data channel is in an invalid state, so that the communication quality of uplink and downlink low-speed ceiling-adjusting data is effectively improved.
In addition, the first optical module/the second optical module may further control the low-speed set-top transmitters of the local terminal and the opposite terminal to recover to the original modulation parameters when the first optical module/the second optical module identifies that the current condition is not met in step 201 according to the detection result, so as to avoid interference on communication of the main data.
EXAMPLE III
The embodiment provides another communication method for a low optical power down-regulation signal, which includes:
step 301, in the process of the data communication of the tuning top, the first optical module performs real-time detection operation to judge whether the number of continuous error reporting times of the check code in the received low-speed tuning top data exceeds a preset threshold (for example, more than 5 continuous times), the received optical power is lower than the conventional sensitivity (for example, -15dBm @25Gbps), and the SD/L OS loss report information and/or the system high error rate feedback information are received, if yes, the next step 302 is continuously executed.
And 302, the first optical module adjusts the modulation parameter of a first low-speed ceiling-adjusting transmitter at the local terminal, and controls the first low-speed ceiling-adjusting transmitter to transmit low-speed ceiling-adjusting data according to the adjusted modulation parameter.
In this embodiment, when the first optical module identifies that the communication quality of the current low-speed overhead data is poor and the high-speed main data channel is in an invalid state, the first optical module actively adjusts a modulation parameter of a first low-speed overhead transmitter of the local terminal, so as to improve the communication quality of the low-speed overhead data transmission channel of the local terminal.
Example four

Different from the conventional optical module, the optical module of this embodiment has a function of detecting the state of the high-speed main data channel and a function of detecting the communication quality of the low-speed overhead data, and sends a parameter adjustment notification to the opposite end according to the detection result to notify the opposite end to adjust the modulation parameter of the transmitter, thereby improving the communication quality of the uplink/downlink low-speed overhead data.
In addition, the MCU is further configured to adjust a modulation parameter of the local low-speed set-top transmitter before transmitting the low-speed set-top data including the parameter adjustment notification to the opposite end, and control the local low-speed set-top transmitter to transmit the low-speed set-top data to the opposite end according to the adjusted modulation parameter, thereby simultaneously improving communication quality of the uplink and downlink low-speed set-top data.
