摘　　要：分析了基于G.652光纤的超长跨距无中继全光通信系统主要特点,介绍了系统结构及组成单元主要功能。对于损耗、色散、非线性、光信噪比等影响系统超长跨距传输的关键因素进行了研究,并针对这些限制结合实际经验提出了相应的解决办法,如采用高增益低噪声EDFA技术、远程遥泵光放大技术、分布式拉曼光放大技术、动态色散补偿技术、光纤非线性抑制技术和级联编码超强前向纠错技术等,可为同类系统的规划和设计提供参考。The characteristics of ultra-long span unrepeated all-optical communication system with G.652 fiber are analyzed.The system structure and primary functions of some composing portions are described.The key factors influencing ultra-long span transmission,which are attenuation,dispersion,nonlinearity,OSNR and so on,are researched.With practical experience,a great many solutions for these restraining elements are proposed,such as using high gain and low noise EDFA,DRA,remote pumped amplifier,dynamic dispersion compensation,fiber nonlinearity restraining and concatenated super FEC.These solutions can provide a good reference for the layout and design of long span unrepeated transmission system.
