After the Optical cable is cut off, the conventional method is that equipment reports a signal alarm, a network maintenance worker inquires about the type of a fault, and after the fault caused by the interruption of the Optical cable is confirmed, the operation and maintenance worker carries an Optical Time Domain Reflectometer (OTDR) to go to a line with the fault for troubleshooting, and an interruption point is determined so as to repair the Optical cable. This method, however, results in a delay in cable maintenance work due to manual triggering after confirming the occurrence of a cable break fault.

The invention is described below in conjunction with the scenario embodiments.
First, an existing optical transmission system integrated with OTDR is introduced, and its structure is shown in fig. 7, where an e-OTDR (the same as the OTDR) having a function of detecting the length of an optical fiber is located at a transmitting end of an optical transmission device, and detection light enters an optical fiber transmission link through hierarchical multiplexing. Wherein, detecting light and signals in the optical fiber line use different wavelengths: the signal is generally in the wavelength range of 1530-1560 nm, and the wavelength of the OTDR detection light is generally 1500 nm. The e-OTDR uses the reflected light generated by backscattering and reflection at the section of the optical fiber when the light is transmitted in the optical fiber to test the length of the optical fiber, thereby positioning the breakpoint.
In order to solve the problem of the existing optical cable maintenance work lag, the embodiment of the invention provides an optical fiber fault detection device, which can automatically start an optical cable length measurement process when an optical cable (optical fiber) is interrupted, and simultaneously give an optimal position for maintenance operation according to optical cable length information stored in a system. As shown in fig. 8, the system is different from the system shown in fig. 7 in that an e-OTDR module in the embodiment of the present invention is located at a downstream receiving end, and an optical power detection device is added.
When the optical fiber at the position shown in fig. 8 has a break fault, the optical amplifier OA2 located downstream of the fault detects no light received, and a signal break alarm is generated inside the system and reported to the management platform, but the alarm cannot confirm whether the optical fiber is broken or the light received due to other device faults exists, because the upstream optical amplifier OA1 also causes the light received by OA 2.
The e-OTDR detects whether light exists or not in an optical fiber line in real time through an optical power detection device, if no light is detected, a pulse signal is generated to directly trigger the e-OTDR to generate detection light to measure the length of the optical fiber, and test data are reported to a management platform.
The management platform will execute the flow shown in fig. 9, as follows:
step 901: the management platform receives a receive light alarm sent by OA 2;
step 902: the management platform receives a length measurement result sent by the e-OTDR;
step 903: the management platform compares the normal length of the link stored in the system with the reported length measurement result, and if the length measurement result is equal to the normal length, the step 904 is executed: if the length measurement result is less than the normal length, go to step 905;
step 904: determining that not a line fault, but an upstream device fault;
step 905: judging that light reception is not due to the optical fiber interruption;
step 906: the distance between the interruption point and the upstream and downstream points is calculated (the fault occurrence place is determined), so that whether the upstream maintenance personnel starts the maintenance conveniently or the downstream maintenance personnel starts the maintenance can be recommended.
The embodiment of the invention realizes that the optical fiber length measuring process is automatically started when the optical fiber is interrupted by the optical power detection device preset at the receiving end, and the optimal position for maintenance operation can be given according to the stored optical fiber length information, so that the process of initiating the optical fiber length measuring process by manual intervention can be omitted, the fault can be accurately positioned, the time for judging whether the optical fiber is interrupted and positioning the breakpoint position can be shortened, and the loss brought to communication can be reduced.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
