摘要
偏振模色散(PMD)是对高速长距离光纤传输系统影响较大的一个因素,文章论述了PMD对光纤通信系统的影响,建立了光纤通信系统中PMD影响的理论模型,在分析单通道一阶补偿方法的局限性的同时,对高阶PMD及其补偿问题进行了分析与讨论,提出了二阶PMD补偿方案,并对该方案进行了研究。
Polarization Mode Dispersion （PMD） is one of the factors that has fairly large impacts on high-speed long-haul fiber optic transmission systems. This article expounds the influences of PMD on the fiber-optic communication system, establishes the theoretical model, analyzes and discusses the higher-order PMD and its compensation while analyzing the limitations of the single channel 1st-order compensation method, presents 2nd-order PMD compensation method and conducts the research on this method.
