摘要

随着光放大器和色度色散补偿技术的不断提高

光纤的偏振模色散（ PMD）已经成为超高速、超长距离光纤通信系统发展的主要障碍 .在 40 Gbit/s或更高速率的光纤通信系统中

PMD的影响已不可忽略

必须考虑 PMD的补偿问题 .从高阶 PMD对 40 Gbit/s NRZ系统影响的数值模拟发现

当光纤中 PMD高阶效应比较明显时

将严重劣化一阶 PMD补偿的效果 .另外

通过对两种高阶 PMD补偿器的比较介绍

认为两段级联的高阶 PMD补偿系统是一种比较现实的补偿方法

Abstract

When attenuation and chromatic dispersion are compensated for

polarization mode dispersion （PMD） in optical fibers is regarded as one of the dominant obstacles in optical communication systems having bit rates of 40 Gbit/s and beyond and transmission distance of several thousand kilometers. From the simulation of second order PMD in 40 Gbit/s NRZ optical communication system

we found that high order PMD in optical fibers can degrade the 1st order compensation effect severely. In this paper

we also introduce two high order PMD compensators on the basis of PMD vector and Jones matrix respectively and the two staged higher order PMD compensator using a fixed differential group delay （DGD） section followed by a variable section is preferred.
