SUMMARY OF THE INVENTION The object of the present invention is to provide an optical network fiber route identification and monitoring system and method thereof, and particularly to a passive optical network fiber route identification and monitoring system and method thereof, which are simple and low in cost, and When there is a problem with the road communication service system, the general optical time domain reflector and the optical wavelength division multiplexer can be used in the general equipment room to identify the fiber routing and monitor whether the wire breakage or the optical loss value is too large. Fiber routing issues. 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. (reflectionpeak), use the 0TDR test on the machine room side. The system comprises: a split-wave multiplexer for integrating the optical signal of the service band and the monitoring band into the optical fiber, or outputting the service band and the monitoring band of the optical fiber from different output ports respectively; a 1x2 light divergence And connecting the monitoring band output section of the demultiplexer and introducing the monitoring band light into an optical circuit of the identification peak distance adjusting fiber and the adjustable optical attenuator, and coupling the monitoring light wave back to the fiber to generate a specific distance and height Identifying the peak; adjusting the peak distance adjustment fiber to delay monitoring the time when the 0TDR pulse wave is optically coupled back to the fiber to adjust the display peak on the 〇T〇R test chart; and controlling the computer to capture the optical time domain reflector The measured waveform diagram is analyzed to obtain the latest state information of the entire divergent fiber routing; an adjustable optical attenuator is used to adjust the optical power of the test pulse wave optical coupling back to the fiber routing; an optical time domain reflector is used To transmit and receive monitoring waves; an optical path selector for 0TDR and routing of the fiber to be tested. 1359577 _ _ * -_ Since the fiber routing identification and monitoring module can cooperate with the different routing lengths of the optical network, adjust the length of the fiber in the module, the optical attenuation value and the divergence rate of the optical splitter (Split Rati.) On the OTDR test curve, different heights are generated at specific ages. Different distances can be set for different divergent routes. Therefore, different fiber routings and obstacles can be easily identified. The height of the identified peak represents the intensity of the light transmitted to the user, and the communication quality of the different route can be tested by monitoring the height change of the peak '. In addition, the height of the identification peak can be adjusted to reflect peaks that can be generated by general fiber routing, such as fiber breakpoints, fiber connector contacts, etc.; therefore, the ® identification peak can be easily separated from other reflection peaks. If the automatic control computer is used to compare the measured data to determine the latest state of the divergent fiber routing, it is used as the basis for the alarm and subsequent processing. [Embodiment] Please refer to FIG. 1 , which is a schematic structural diagram of an optical network fiber route identification and monitoring system and method thereof provided by the present invention, which 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 supplied to the optical fiber, or the service band 14 and the monitoring band 17 of the optical fiber are respectively outputted by different output ports; the 1x2 optical splitter 22 is connected to the monitoring band 17 output segment of the split-multiplexer 15 The monitoring band 17 light is introduced into the light-loop 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 fiber to generate the identification peak 28 of a specific distance and height; - an identification peak distance adjustment The optical fiber 23 is configured to delay monitoring the time that the optical time domain reflector pulse light is engaged with 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 for adjusting the test Pulse light is coupled back to the optical power of the fiber route; an optical time domain reflector 16 is used to transmit and receive the monitoring band 17; 1359577 - Control computer 25, afterglow_reflection!! 16 measured wave sheds, (4) analysis to obtain the latest status information of the entire divergent routing fiber 20; and an optical channel selector (optical channel selector) 26 for the optical time domain reflector 16 and selecting the fiber to be tested . As shown in FIG. 1, the monitoring device is placed in the machine room 12 and the branch routing optical fiber end optical network unit 10, and the monitoring test equipment placed after the optical line terminal (OpticaijjjjeTejminaLOLT) 13 of the equipment room 12 is used to control the computer 25 and light. The domain reflector 16 and the splitter multiplexer 15 are configured to call out the monitoring band and take the waveform diagram of the optical time domain reflector, and perform a comparative analysis to obtain the latest state information of the entire divergent fiber routing. The monitoring device placed in front of the divergent routing fiber end optical network unit 10 is a fiber routing identification and monitoring module 11, which is composed of a splitting multiplexer 21, a 1x2 optical splitter 22, an identification peak distance adjusting fiber 23 and an adjustable light attenuation. The device 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 demultiplexer 15 , and the monitoring device 0TDR 16 sends the optical signal of the monitoring band 17 to the demultiplexer 15 , and the demultiplexer * 丨 5 The optical signal is integrated and sent out, and is split to the respective branch routing fibers 2 via the main routing fiber 18 to the optical splitter 19. When the optical signal reaches the end of each route, the fiber path identification and monitoring module 11 is first entered. Here, the optical signal of the service band 14 can be provided to the user telecommunication service via the optical multiplexer 21 in the optical fiber route identification and monitoring module 11 and into the optical network unit (0NU) 10 '. The optical signal of the monitoring band 15 is introduced into the 1 χ 2 optical splitter 22 and divided into two paths ' respectively, through the specific length of the identification peak distance adjusting fiber 23 and the adjustable optical attenuator 24 'back to the 1x2 optical splitter 22 and merged into the splitting multiplexer twenty one. Then, via the divergent routing fiber 8 ί .S': 5 1359577 2 〇, the optical splitter 19' main routing fiber 18, the split multiplexer 15, returns to the monitoring device view i6. According to the working principle of OTDR16 test, the fiber routing identification and monitoring module will generate an identification peak 27 with adjustable height and distance on its test curve. As shown in Figure 3, the identification peaks of different heights and distances in the three represent the different routes and The divergent route H(4)_ Μ can operate the test curve data 'for the routing route _ scale 27 _ analysis, then _ the entire divergent fiber routing the latest state information, and as the basis for subsequent processes such as alarms. As shown in Figure 4, when there is a divergence in the fiber routing, the route _ axis π will disappear and the routing obstacle reflection peak will be added to the OTDR test curve. Therefore, the obstacle route can be clearly determined and the position of the obstacle point can be found. The supervisory section used in the present invention can be used for any communication band that is not in the carrier band. The invention can also be matched with an optical path selector (0pticalCh_1Select〇r, 〇cs) 26, as shown in Fig. 5, the monitoring principle is such as Guanyi', but the optical path selector can be switched via the control computer according to the monitoring process to switch different optical paths.
