随着Internet的迅速普及以及宽带综合业务数字网(B-ISDN)的快速发展，人们对信息的需求呈现出爆炸性的增长，几乎是每半年翻一番。在这样的背景下，信息高速公路建设已成为世界性热潮。而作为信息高速公路的核心和支柱的光纤通信技术更是成为重中之重。很多国家和地区不遗余力地斥巨资发展光纤通信技术及其产业，光纤通信事业得到了空前发展。光纤通信的传输速率和距离在不断增加，导致色散对系统性能的影响越来越大，成为限制光纤通信系统容量和距离的最终因素，所以需要人们深入研究，寻求一种或几种便于光纤通信网升级、经济实用、易于实现和推广的色散补偿技术。
本文首先从理论对色散和非线性进行了细致的研究，分析了光纤非线性效应对正、负色散光纤中光脉冲传输的影响。然后对偏振模色散的有关概念及其特性等进行总结，利用Q因子作为反馈控制信号进行一阶PMD动态补偿，并给出控制算法。最后介绍了其他的色散补偿技术。

With the rapidly growing popularity of Internet and Broadband Integrated Services Digital Network (B-ISDN) and the rapid development of the information needs of people emerged explosive growth, almost doubling every six months. In this context, building the information superhighway has become a worldwide craze. And as the information superhighway and the core pillars of optical fiber communications technology is a top priority. Many countries and regions spare no effort in the development of optical communication technology spending huge sums - and its industries, and optical fiber communications industry has undergone an unprecedented development. Fiber-optic communication transmission rate and distance on the increase, resulting dispersion effects on system performance more and more, become a restricted capacity optical fiber communication systems and distance, the ultimate factor, so people need in-depth study to find one or more of the easy - fiber communication network upgrades
