Problems solved by technology

[0003] With the large-scale construction and operation of power optical fiber communication networks, the length of power optical cables and the number of optical fibers represented by fully insulated optical unit phase conductors (Insulated Optical Unit Phase Conductor, IOPPC) continue to increase, and the scale of optical fiber distribution systems is increasing. The number of optical fiber link components is large and the connection relationship is complex, which brings many problems such as management and fault monitoring. The specific performance is the lack of fault monitoring technology for optical fiber links, low fault monitoring accuracy and serious data acquisition. Lag and other problems, there is an urgent need for effective intelligent fault monitoring methods to ensure the stable and reliable operation of the power optical fiber communication network

[0004] At present, the existing optical fiber link fault monitoring method is mainly that the operation and maintenance personnel judge the damaged optical fiber components based on experience, manually check the business data transmitted by them to determine the affected services, and notify the operation and maintenance personnel to correct the damaged optical fiber components. Maintenance of damaged optical fiber components, low work efficiency
