Polarization Mode Dispersion Effects on Signal Quality and Compensation Methods

With the ever-increasing bandwidth demand, high-speed optical systems are currently widely used to transmit various traffic over long distances. The main direction of development of optical communication systems is associated with the increase in the information transmission rate. However, the performance of long-haul high-speed optical systems is severely affected by linear and nonlinear transmission impairments, such as chromatic dispersion, polarization mode dispersion and nonlinear phase noise. In this paper the effects of the polarization mode dispersion on the system performance and its effects along with chromatic dispersion have been evaluated, and compensation methods have been proposed.
