OPGW光缆维护中测试问题的探讨

Discussion on OPGW optical cable maintenance tests

山西电力光纤通信网络是由三层SDH光设备组成的立体网络系统。由于采用电力特种光缆OPGW／ADSS作为网络的传输介质，网络生存性和传输可靠性得到很大的提高。相应地，保证光缆线路的各项传输特性指标也日渐成为维护工作的重点。文章就OPGW线路维护中遇到的常见测试问题和产生原因、具体的解决办法做了一些简要介绍，对光纤通信工程设计、施工、维护中改善和优化光纤通信网络传输性能和运行维护工作有一定的指导意义。

Shanxi electric power optical fiber communication network is of the three-layer network system which is composed by SDH equipment. Because of the use of electric power special optical cable OPGW/ADSS as the network transmission medium, the network survivability and the transmission reliability obtain the large enhancement. So to keep the transmission characteristic target of each fiber optic cable line becomes the key point of the day to day maintenance work. The article has made some brief introductions to the common test problems of the OPGW line maintenance and the causes of the problems, and the solution to the problems, which will be instructive to the design of the optical fiber communication projects, and the construction of the communication projects, and the transmission performance improvement and the optimization of the optical fiber communication network and the operation maintenance work.
