摘　　要：介绍了大跨距无中继光纤通信系统,该系统与一般光纤通信系统不同的是,除了有光纤功率放大器和前置放大器外,还有远泵光纤功率放大器、远泵光纤前置放大器以及喇曼放大器和前向误码纠错技术等。这种系统主要应用于跨距已经超过了一般情况的光通信系统,但又不是特别长的某些特殊场合。提出了该通信系统可以作为我国电力系统在地理和环境条件复杂的西部地区,构建光纤通信系统的一种技术选择,并说明了选择这种技术的现实可行性。Long Span Unrepeated Fiber Communication System is introduced in this paper. The difference between the common optical communication system and this system is that long span unrepeated fiber communication system is made up of not only fiber booster and fiber preamplifier but also remote-pumped fiber booster, remote-pumped fiber preamplifier, Raman amplifier and FEC technique etc. This kind of system is usually used in some special occasions where the span is longer than the span of common fiber communication system but not too long. The system is a technical option for electric power communication in West China with complicated geography and environment conditions. And the technique is realistically feasible.
