The design of modern wavelength-division-multiplexed (WDM) optical transmission systems has made advanced optical modulation formats a key ingredient. In this paper, we show PMD-induced system degradation through simulation. We found out that DQPSK is highly tolerant compared to RZ, however, RZ is more tolerant than NRZ.
