The optical cable O&M solution integrates an optical line protection system (OLP) and an optical line monitoring system (OLM). When the fiber attenuation of the transmission line becomes large or the fiber accidentally breaks, leading to communication quality degradation or communication interruption, the optical line protection system can quickly and automatically switch the primary routing to the secondary routing, and at the same time, the OLM system can quickly and accurately locate the fault point, thus ensuring the normal operation of the communication line and greatly shortening the time for optical cable line repair. The whole solution realizes uninterrupted protection of optical transmission service, timely locates fault point, realizes rapid repair of optical cable line fault, and forms an integrated intelligent operation and maintenance solution integrating service primary and secondary routing protection, optical line fault location and optical line resource management.
