We show that periodic-group-delay dispersion compensators can significantly suppress inter-channel nonlinearities in a WDM coherent polarization-division-multiplexed quardrature-phase-shift-keying system and make systems with dispersion management have higher nonlinear tolerance than those with only electronic dispersion compensation.
To study the dynamic performance of a polarizationmode-dispersion compensator (PMDC), a continuous PMD model and a dynamic PMDC model are presented. The continuous PMD model generates continuous PMD and state of polarization (SOP) variations. The statistics of the SOP variation generated by the continuous PMD model follows the Rayleigh distribution, and the SOP variation amplitude scales with the...
