Effects and numerical simulation of PMD on optical fiber TV transmission system

Along with progresses in high-speed, wideband long-haul and full service transmission in optical fiber system, the polarization mode dispersion has become one of major limiting factors in term of the system bandwidth and the linearity, and leads to severe signal impairments, especially the second-order PMD for an analog system. Therefore the purpose of the paper is to present a detailed description of PMD effects (in term of composite second-order) on PAL-D 60 channels analog CATV signals and to show the numerical simulations about some important relations between the CSO and the PMD distortion factors. Based on the simulation results, we also discuss a second-order PMD compensation scheme for optical DWDM network, which can efficiently reduce second-order, or even higher-order nonlinear distortions.
