In view of the difficulty in the operation and maintenance of power optical cables in Xinjiang and other large areas

we first investigate several schemes for the compensation

switching and online monitoring of optical path

which are based on optical fiber automatic switching technology and optical power amplification technology. Then we proposes an effective solution for the scheduling and testing of the main and backup optical fibers of the ultra-long-haul optical cable. The results show that the scheme is suitable for the scheduling and monitoring of ultra-long-range optical cables

and it can lay the foundation for the construction of intelligent operation and maintenance systems for ultra-long-range optical cables in the future.
