我们提出了一种在偏振复用超高速传输中由偏振模色散 (PMD) 在存在偏振相关损耗 (PDL) 的情况下引起的新型串扰。当 PMD 和 PDL 同时存在时，两个主偏振态 (PSP) 之间的正交性会降低。因此，两个偏振之间不可避免地会出现串扰，并且在偏振解复用期间阻碍两个通道完全分离。这些效应对偏振复用太比特/秒传输的系统影响也通过实验得到了证明。
We present a new type of crosstalk in a polarization-multiplexed ultrahigh-speed transmission caused by polarization-mode dispersion (PMD) in the presence of polarization-dependent loss (PDL). When PMD and PDL are both present, the orthogonality between two principal states of polarization (PSP) is reduced. As a result, crosstalk inevitably occurs between two polarizations and prevents the two channels from being separated completely during polarization demultiplexing. The system impact of these effects in a polarization-multiplexed terabit/s transmission is also demonstrated experimentally.
