摘　　要：三峡光纤通信系统包括连接电力系统和连接内部各区域业务的光传输设备及有关的PCM设备,承担着交换机联网、数据组网、保护和安控传输等多项业务,所使用的光纤设备种类繁多,分布区域较广。左岸电厂已经成为电力系统通信网中非常重要的节点之一。在三峡公司内部建有光环网,由于暂无法实现双纤自愈环,故采用微波保护,同时原有通信光设备依然沿用,使当前的网络结构复杂。文中在对三峡光纤通信系统进行介绍的同时也提出了针对网络的优化方案。The optical-fiber communication system in Three Gorges consists of light transmission equipments and relative PCM facilities.They interconnect the power communication network,and provide some services in different internal regions.This system undertakes on many functions such as making up of PBX network and data network,transmitting relay protection and security controlling information,and so on.There are many kinds of equipments used in this system that distributed in several regions.The left_bank power plant is one of the key nodes in this network.The FibrLINK has been set up within the Three Gorges project corporation.But the 2F MS_SPRING is not be realized at present,so the microwave channel has to be adopted as a backup channel.The original light transmission equipments are still used and the current network are complex.At last,this paper presents optimization scheme for the Three Gorges optical fiber communication system.
