摘　　要：在电力系统向智能化发展的趋势下,对无中继超长跨距、大容量传输的需求日益迫切。文章介绍了基于双向拉曼系统40×10 Gbit/s超长跨距传输方案的理论研究和实验测试。系统采用超低损光纤作为传输介质,使用增强型前向纠错(Enhanced Forward Error Correction,EFEC)技术和双向拉曼放大技术,实现了40×10 Gbit/s OTN系统300 km无中继的超长距离传输,系统连续运行稳定。实验成果为衡量大容量超长跨距无中继传输的性能、指标和应用标准等提供了实验依据,为今后电力系统对无中继长跨距传输系统的设计提供了参考。The power system is becoming more and more intelligent, thus high capacity and long distance transmission is an urgent task. This paper introduces research and realization on bidirectional Raman system of 40×10 Gbit/s ultra-long haul transmission scheme. This system achieves 300 km ultra-long span unrepeated transmission in 40×10 Gbit/s OTN（Optical Transport Network） optical transmission system by using ultra-low loss optical fi ber as the transmission medium and technologies of enhanced forward error correction（EFEC） and bidirectional Raman fi ber amplifi er. The system runs stably. These obtained practical experimental results provide foundations for the system performances and standards of ultra-long haul transmission measuring, and provide a reference for designing the long distance unrepeated transmission system in power system.
