摘　　要：本文针对青海玉树高海拔地区超长距无中继光纤通信传输系统进行研究,通过分析超长距光传输系统受限因素及关键技术,采用超低损耗光缆、掺铒光纤放大器、光纤拉曼放大器、色散补偿模块、前向纠错编码等先进技术,实现了超长距无中继光传输,解决了玉树联网工程中348 km的超长距通信难题,为电网安全稳定运行提供了可靠的通信通道。In this paper, the high altitude ultra-long span non-repeater optical transmission system in Yu Shu was studied. The limited factors and key technologies of ultra-long span transmission were analyzied.The high altitude ultra-long span nonrepeater optical transmission was achieved through advanced technologies of ultra low loss optical fiber, erbium-doped fiber amplifier, fiber raman amplifier, dispersion compensation module and forward error correction coding.h is successfully applied in the Yushu grid construction for the 348km optical transmission problem. It has guiding significance to the application of the high altitude ultra-long span non-repeater optical transmission system.
