被動式光網路因各分歧路由之架構、辨識與通信品質的監測，一直是 經營業者所困擾的。最早有單獨使用0TDr的監測方式，但在〇丁〇11測試 圖形上，所有分歧路由的信號均疊加在一起，無法單獨識別任一分歧路由。 為解決識別的問題，有的在分歧路由末端加裝主動識別組件，但需配合通 信網路與縣端的控制電腦互動，絲增加監啦統赫度。此外，雖然 有些被動式讀，但使用職方式複雜，當光纖分歧路由多時，辨識工作Passive optical networks have been plagued by operators due to the architecture, identification and communication quality of different routings. At the earliest, there was a monitoring method using 0TDr alone, but on the Kenting 11 test pattern, all the signals of different routes were superimposed, and it was impossible to identify any divergent route separately. In order to solve the problem of identification, some of them add active identification components at the end of the divergent route, but they need to cooperate with the control network of the county network to increase the monitoring system. In addition, although some passive reading, but the use of the mode is complicated, when the fiber is divided by multiple routes, the identification work

Also, the adjustable optical time domain reflector 'can transmit various wavelengths of the monitoring light source' and the domain wave components are added to each of the different routes to solve the identification problem, and the adjustable laser (Tunabie L·) light source and optical circulator are also useful. The design of the optical power meter and the fiber optic light killer (FtoBmggGmtm & FBG) can be used to detect obstacles, but the use of expensive and specially designed instruments due to the increase of optical network components affects communication performance cannot be exemplified. All the shortcomings such as the current situation of the route, in addition to the equipment and components will increase operating costs. It can be seen that there are still many missing items in the above-mentioned household items, which are to be improved. 200901647 The inventor of the present invention, in view of the secrets derived from the above methods, (4) thought to improve and innovate, and after years of painstaking research, finally succeeded in the development of the optical network optical path identification and monitoring system and its method. SUMMARY OF THE INVENTION The object of the present invention is to provide an optical network fiber routing identification and monitoring system and its method, in particular, a passive optical network routing identification and monitoring that is easy to use and low in cost. Method 'When there is a problem with the optical network communication service system, it can be used in the general computer room. The time domain anti-riding and optical splitting hn can be used for fiber routing and can monitor whether the wire breakage or optical loss value is too large. Clarification is a problem with service system terminal equipment or fiber routing. The optical network fiber route identification and monitoring system and method thereof for achieving the above object of the invention are the fiber routing identification and monitoring module installed in the end of each branch route and the optical network unit device.

The system consists of: - split wave township m, integrated with the optical signal of the transmission service band and the monitoring band and sent to the optical fiber, or the service band and the monitoring band of the optical fiber are respectively output by different rotations; 1x2 light The splitter 'connects the monitoring band output section of the split-wave multiplexer and introduces the monitoring band light into the optical loop of the adjustable peak distance adjusting fiber and the adjustable optical attenuator, and then the monitoring and metering Turning and listening to the silk; - discriminating the scale to adjust the fiber 'to delay the monitoring of the time of the TDR pulse wave back to the fiber to adjust the display peak on the 〇TDR test chart display distance; a control computer, when the building takes light The waveform of the domain reflector is measured, and the comparison analysis is transferred to the latest heterogeneous information of the divergent fiber routing; the adjustable optical attenuator is used to adjust the optical power of the test pulse surface and the optical fiber route; A domain reflector for transmitting and receiving a monitoring wave; an optical path selector for routing the TDR and selecting a fiber to be tested. 200901647 Due to the length of the different routing routes between the fiber routing _ and the monitoring group, the adjustment mode __ length, silk reduction and fitness level k ride (SpHt μ〇) on the OTDR job red, in the loss of miscellaneous Set the peak of the unique height. Since different divergent routes can be set to _ _ _ _ and height, it is easy to identify different fiber routing and whether obstacles occur. The height of the identified peak represents the intensity of the transmitted household light, and the communication quality of the different routing can be tested by monitoring the height change of the identified peak. In addition, the height of the peak can be adjusted to reflect the peaks that can be generated by the general fiber routing, such as fiber breakpoints, fiber connector contacts, etc.; therefore, the identification peak can be (4) separated from other reflection peaks. If the measurement data is compared and analyzed using an automatic control computer, the most remaining state of the divergent fiber routing is determined as the basis for the alarm and subsequent processing. [Embodiment] Referring to FIG. 1, a schematic diagram of an optical network fiber route identification and monitoring system and a method thereof according to the present invention mainly includes: a wavelength division multiplexer 15 for using a service band 14 and a monitoring band. The optical signal of 17 is integrated and sent into the optical fiber, or the service band 14 and the monitoring band 17 of the optical fiber are respectively outputted by different rounds; - 1x2 optical splitter 22, connected to the monitoring band of the split-multiplexer 15 for 17 rounds of output 埠And the monitoring band 17 light is introduced into the optical circuit of the identification peak distance adjusting fiber 23 and the adjustable optical attenuator 24, and then the monitoring light wave is coupled back to the optical fiber to generate the identification peak 28 of a specific distance and height; 23, used to delay monitoring the time when the optical time domain reflector pulse light is coupled back to the optical fiber to adjust the display peak 28 to display the distance on the optical time domain reflector test chart; - the adjustable optical attenuator 24' is used to adjust the test pulse light Optical power coupled to the fiber route; - Optical time domain reflector 16 for transmitting and receiving the monitoring band I?; 200901647 A control computer 25' extracting the optical time domain reflector 16 The shape map is analyzed to obtain the latest state information of the entire divergent routing fiber; and an optical channel selector 26 is used for the optical time domain reflector 16 to select the fiber to be tested. As shown in FIG. 1, the monitoring device is placed in the equipment room 12 and the branch routing optical fiber end optical network unit 10, and is placed in the equipment room 12 optical line terminal (Optical Line Terminal 'OLT) 13 - the monitoring test equipment is the control computer 25 The optical time domain reflector 16 and the wavelength division multiplexer 15 are connected to the monitoring band, and the waveforms of the optical time domain reflector are measured, and the comparison analysis is performed to obtain the latest divergent fiber routing. Status information. The monitoring device disposed in the optical network unit 1 of the divergent routing fiber is a fiber routing identification and monitoring module 11, which is composed of a splitting multiplexer 21, an optical splitter 22, an identification peak distance adjusting fiber 23, and an adjustable light. The attenuator 24 is constructed. The process of monitoring and analysis is described below. The optical line terminal 13 sends the communication optical signal of the service band 14 to the branching multiplexer 15, and the device 〇TDR16 sends the optical signal of the monitoring band 17 to the branching multiplexer 15, and the demultiplexer 15 performs the two types. The optical signals of the band are integrated and sent out, and are branched to the respective branch routing fibers 20 via the main routing fiber 18 to the optical splitter 19. When the optical signal reaches the end of each route, it first enters the fiber path identification and test module. In this case, the optical signal of the service band 丨4 can be accessed by the optical multiplexer 21 in the fiber-optic route identification and monitoring module 11 to enter the optical network unit (ONU) 10 to provide user telecommunication services. The optical signal of the monitoring band 15 is introduced into the 1χ2 optical splitter and divided into two paths, and the optical fiber 23 and the adjustable optical attenuator are respectively returned through the identification peak distance of the specific length! The 1x2 optical splitter 22 is merged into the split multiplexer 21. Then, it returns to the monitoring device 〇TDR16 via the divergent routing optical fiber 200901647 2, the optical splitter 19, the main routing optical fiber ι8, and the demultiplexing multiplexer 15. According to the OTDR16 test working principle, the fiber routing identification and monitoring module u will generate an identification peak 27 of adjustable twist and distance on its test curve, as shown in Figure 3. The identified peaks of different heights and distances in Figure 3 represent the different divergent routes and the different routing states. The control computer 25 can retrieve the test curve data, and compare and analyze the route identification peaks 27 of different routes, so as to obtain the latest status information of the entire divergent fiber routing, and use it as a basis for subsequent processes such as alarms. It is shown that δ has a disconnection obstacle for the fiber routing, and the route identification and monitoring peak 27 of this route will disappear and increase the reflection point of the route obstacle point on the OTDR test curve. Therefore, it is possible to clearly determine the obstacle route and find the obstacle. Point location. The monitoring band used in the present invention can use any fiber-optic communication band that does not conflict with the service band. The invention can also be matched with an optical path selector (0pticalChannelSelect〇r 〇cs) 26, as shown in Fig. 5, the monitoring principle is the same as the figure-'but the optical path selector can be switched via the control computer according to the monitoring process, and the optical fiber of the different optical path (4) can be switched. She has no domain expansion to improve the use efficiency of (4) devices and reduce the unit cost of monitoring. The optical network light age provided by the invention is compared with the foregoing cited documents and other technologies, and has the following advantages: 1. The invention can be monitored at the machine room side. The specific route identification and monitoring device with the end provides a light, sin, intervening, economical passive optical network multi-divided fiber routing monitoring method. 2. The divergent routing fiber of the present invention _ mode can be used to identify the peak _ out of the divergent path. The fiber is _ and _ road product H _ disparate road _ network 200901647 road monitoring. 3. The present invention has the problem that the peak-to-peak collision is called the demand material and the identification peak overlap of the same length divergent route is avoided. 4. The invention can carry out single-end and long-term automatic monitoring in the equipment room, and can quickly and correctly understand the service system or rely on it. _ 'The secrets of each branch can be used for preventive maintenance and provide better service quality. . 〇 5. The invention can reduce the cost of personnel and personnel, and can surely scream the reliability and stability of the optical network to improve the efficiency of the county protection, and the conversion benefit is very obvious. In the case of the singularity of the singularity, the singularity of the singularity of the singularity of the singularity of the present invention is not intended to be used in the context of the invention. The patent scope of this case. The case described in T is not only innovative in terms of space type, but also can enhance many functions in comparison with the use of customary items.
