摘　　要：在西部地区电力通信网络的建设中,长站距传输是一个必须考虑的问题。文章介绍了四川电力"新甘石"工程中两段超长站距无中继SDH光传输通道的设计方法和施工经验。工程利用遥泵放大、超强前向误码纠错、波长转换等技术搭建系统,成功打通了220 k V甘孜变—220 k V西地变(361 km)和220 k V甘孜变—220 k V榆林变(348 km)2.5 G SDH光路,为遥泵技术在电力通信系统中的广泛应用提供了建设经验。When constructing electric power communication networks in western areas, the issue of long-span transmission must be considered. This paper introduces the design and construction of two ultra-long unrepeated SDH transmission channels in the ＂Xinganshi＂ project operated by Sichan electric power company. Applying remote pump amplifying, enhanced forward error correction and wavelength conversion, the project builds two SDH light paths--＂220 kV Ganzi -220 kV Xidi＂ （361 km） and ＂220 kV Ganzi -220 kV Yulin＂ （348 kin） at the speed of 2.5 Gbps, which offers experiences for comprehensive use of the remote pump in constructing electric power communication systems.
