摘　　要：介绍了限制2.5 Gbit/s光传输系统超长中继距离传输的4个主要因素:衰减、色散、信噪比、非线性效应,有针对性地提出了掺饵光纤放大器技术、拉曼放大器技术、遥泵放大器技术、色散补偿技术、前向纠错技术等多种克服技术,给出各种克服技术的性能参数,提出了工程中不同站距情况下各种技术的组合方案,总结了2.5 Gbit/s光传输系统工程应用时的最大中继距离。This article briefly introduces the four limiting factors of ultra-long repeating distance for 2.5 Gbit/s optical transmission system,which are attenuation,dispersion,signal-noise ratio and nonlinear effect.It advances the corresponding solutions such as erbium-doped fiber amplifier,distributed Raman amplifier,remote optical pump amplifier,forward correction as well as dispersion compensation,and proposes the performance parameters for each solution.The technical combination for different repeating distance and the maximum repeating distance for 2.5 Gbit/s optical transmission system are also given in the paper.
