OSC (Optical Supervising Channel) optical module with OTDR (Optical Time Domain Reflectometer)) function and method for realizing real-time and interruption service detection thereof

Abstract

The invention relates to the technical field of optical communication and specifically discloses an OSC (Optical Supervising Channel) optical module with an OTDR (Optical Time Domain Reflectometer)) function and a method for realizing real-time and interruption service detection thereof. The OSC module comprises an OSC receiving end, a BOSA (Bi-Directional Optical Sub-Assembly) as a module sending end, and a laser driver, an OTDR control circuit and a breakpoint detection module which are electrically connected with the BOSA. An optical transmitting laser and an OTDR receiving end are integrated in the BOSA. One end of the OTDR control circuit is electrically connected with a power-off detection module, and the laser driver and the other end of the OTDR control circuit are electrically connected with an MCU. The MCU is in communication connection with an OSC system device through a communication bus. According to the module and the method, two functions of real-time service detection and interruption service detection are integrated and can be switched randomly; real-time detection and positioning can be realized without modifying the OSC system device; a technician does not need to go to the site, the labor cost and time can be greatly reduced, and the module and the method are applicable to industrial large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical monitoring channel (OSC: Optical Supervising Channel) optical module with an optical time domain reflectometer (OTDR: Optical Time Domain Reflectometer), and a method for realizing real-time service and interrupt service detection thereof. . Background technique [0002] DWDM (Dense Wavelength Division Multiplexing) technology is widely used in global core network long-distance trunk lines and metropolitan area network transmission systems, making full use of the huge potential bandwidth of optical fibers and meeting people's needs for voice, data and multimedia services. of growing. In order to monitor network lines in a timely manner, find faults and solve them as soon as possible, so that the network can run normally, the concept of optical monitoring channel came into being. This channel is OSC. [0003] Optical fiber transmission will inevitably ca...

AI Technical Summary

Problems solved by technology

Existing OSC optical modules generally do not have an OTDR function, which is basically tested by technicians using a dedicated OTDR and supporting test equipment. This method is not only complicated to test the networking scheme, but the price of OTDR equipment and labor costs are high, and the communication system Repairs are slow and take a long time
