Paper Abstract

The relationships between Degree of Polarization (DOP) and Polarization Mode Dispersion (PMD) for different modulation format signals are discussed not only in theory but also in experiment, which include the NRZ, RZ, CSRZ, DPSK, RZ-DPSK and CSRZ-DPSK signals. The RZ signals with different duty cycle are also analyzed and compared. The results are found that the optical signals DGD/DOP relation depends on their optical spectrum structure as well as the modulation formats, and the phase-shift-keying signal with free chirp will provide better performance in the PMD compensation based on the DOP feedback control because of the DOP sensitivity and wide monitoring window, besides, the CSRZ has the stalest character for the variety of modulation chirp.
