虽然偏振模色散 (PMD) 极大地损害了传统的高速单载波系统，但研究表明，对于相干光正交频分复用系统 (CO-OFDM) 等多载波系统，PMD 不仅不会造成任何损害，而且还提供了偏振分集的优势，以防止偏振相关损耗引起的衰落，从而提高系统裕度。还预测了 PMD 对减少 CO-OFDM 系统中光纤非线性的好处
Although polarization-mode dispersion (PMD) greatly impairs conventional high-speed single-carrier systems, it is shown that for multicarrier systems such as coherent optical orthogonal frequency-division-multiplexed systems (CO-OFDM), not only does PMD not cause any impairment, but it also provides a benefit of polarization diversity against polarization-dependent-loss-induced fading and consequently improves the system margin. The PMD benefit to fiber nonlinearity reduction in CO-OFDM systems is also predicted
