摘　　要：提出了一种以周期配置的级联在线半导体光放大器(SOA)同时补偿光纤的损耗和色散的新色散补偿技术。通过系统仿真分析了10 Gbit/s级联在线增益饱和SOA的色散补偿效果,以及常规单模光纤通信系统中SOA饱和增益、放大器间距、脉冲占空比、脉冲阶数等参数对系统传输性能的影响,并由此给出获得最佳色散补偿效果的系统和放大器参数及配置。In this paper, we present a new technology that can compensate both fiber loss and dispersion by period placing cascaded in-line semiconductor optical amplifier （SOA） in fiber transmission links. We study the effect of dispersion compensation on 10 Gbit/s normal single mode fiber optical transmission system employing cascaded in-line gain saturated SOA by system simulations. We also study the influences of different pulse and system parameters, such as pulse duty cycle pulse index amplifier saturation gain and distance between amplifiers, on system performance, and give amplifier and system parameters that can acquire optimum dispersion compensation.
