摘要
PMD是对高速长距离光纤传输系统影响较大的一个因素。描述了一阶PMD补偿的基本原理及其局限性,给出PMD补偿系统的一般模型,对各个模块和关键技术进行较为详细的讨论。对高阶PMD及其补偿问题进行分析与讨论,并实现了一种二阶PMD补偿器的具体设计与实验研究。
The main parameter and the numerical model for analyzing the influences of PMD on high speed,long-distance optical transmission system are introduced.By describing the basic principle and limits of first order PMD compensation,the idea that the first and higher-order PMD must be compensated is discussed.A second-order PMD compensation is designed and realized.
