摘　　要：超长站距光通信技术已成为跨大区交直流输电的重要技术基础。文章分析比较了超长站距光通信系统的各种关键技术,详细阐述了光信噪比(ONSR)的计算和提高OSNR方法,从建设流程、光缆线路等几方面探讨了超长站距光通信工程建设要求,同时提出了工程测试方案。Ultra-long span optical communication technology has become one of the important support technologies of interregional AC/DC power transmission. The paper analyses and compares each kind of key technology of ultra-long span optical communication system, particularly expatiates calculation of ONSR and methods of improving OSNR, discusses requirement of ultra-long span optical communication engineering construction from some aspects of construction flow, optical cable line and etc. , the paper also puts forward the engineering test scheme.
