Abstract—We used carrier suppressed return to zero–differential phase shift keying (CSRZ-DPSK) and CSRZ–differential quadrature phase shift keying (CSRZ-DQPSK) to find out their comparative tolerance as polarization mode dispersion (PMD) compensator in the presence of fiber nonlinearities. Their performances are evaluated in terms of Q-factor surface diagram and contour map. It is noted that CSRZ-DQPSK is efficient as PMD compensator and fiber nonlinearities help reduce the deteriorating effect of PMD.

Index Terms—polarization mode dispersion, compensation, optical communication, CSRZ-DPSK, CSRZ-DQPSK
