Application of Optical Fiber Multiplication System Based on Line 1+1 Protection in Operation and Maintenance of Power Optical Cable

电力通信网以光纤通信为主,主要承载着电力生产中的安全控制、监控继电保护、调度电话、变电站监控以及企业信息化等重要业务。随着电力光纤通信网络规模的逐步扩大,光缆线路纷繁复杂、节点众多,运维数据越来越大,由于泛在电力物联网催生许多新的光业务,需要占用纤芯资源,同时由于光缆自身原因以及外界因素的影响,导致光缆质量下降或中断,从而造成纤芯资源紧张。本文基于波分复用(WDM)原理,利用光纤自动切换保护(OLP)、波长转换(OEO)技术解决光缆运维中纤芯资源短缺等情况。探索一套适用于电力通信网光缆运行维护的光纤资源优化技术方案。光纤倍增系统是解决电力光纤通信因泛在电力物联网建设带来的光缆纤芯资源不足的最优选择。通过实际场景应用和测试结果,表明光纤倍增系统具有安全可靠、技术成熟、成本低,部署快捷等优点,对于电力专网内光纤资源紧张的光缆线路,可利用光纤倍增设备合理承载新增业务通道,以解决纤芯资源短缺的难题。

The power communication network is mainly based on optical fiber communication,which mainly carries the important business of safety control,monitoring relay protection,dispatching telephone,substation monitoring and enterprise informatization in power production.With the gradual expansion of the scale of power optical fiber communication network,optical cable lines are complex,nodes are numerous,and the operation and maintenance data is becoming larger and larger.Due to the ubiquitous power Internet of things,many new optical services need to occupy fiber core resources.At the same time,due to the influence of optical cable itself and external factors,the quality of optical cable is reduced or interrupted,resulting in the shortage of fiber core resources.
