Abstract

We study the polarization-mode dispersion (PMD) compensation and mitigation performance, using a single PMD compensator to compensate several channels at the same time with degree of polarization (DOP) as the feedback signal in a 2 40 / Gb s × WDM system. Particle-swarm optimization (PSO) algorithm is used to search and track the dynamic degree of polarization (DOP) to achieve the adaptive PMD compensation. New modulation formats are used to mitigate PMD, and the dynamic combination of PMD mitigation taking CSRZDPSK and CSRZDQPSK as the advanced modulation formats have been successfully completed. The numerical results show that the differential phase-shift keyed (DPSK) and differential quadrature phase shift keying (DQPSK) modulation formats are more suitable for PMD mitigation system than the on-off keying (OOK) modulation format. Furthermore, DQPSK format can simultaneously double WDM spectrum-packing efficiency and upgrade the system capacity while it can still has the same mitigation performance as the DPSK format in the PMD compensation system. These features make them greatly attractive for high-speed long-haul WDM system.
