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.
