高速光纤通信系统中PMD补偿方法研究

摘要

从偏振模色散（PMD）基本概念出发，具体从电域补偿和光域补偿两个方向探讨了PMD的补偿原理和方法，并分析出两个方向的补偿方法虽然本质相同，但后者比前者的效果更好，是现今的研究的主流；最后介绍了抑制PMD的新技术。%This article embarks from the polarization mold chromatic dispersion （PMD） basic concept and discusses the PMD compensation principle and the method from two directions of the electricity territory and the light territory. Then this article analyzes two directions of compensating process,making a conclusion that the essence of two methods is the same, but the latter is better than the former in effect and nowadays the latter is mainstream in research. Finally this article introduced the new technology of suppressing PMD.
