众所周知，交叉相位调制引起的偏振旋转，交叉偏振调制（XPolM），显著地降低偏振模色散（PMD）补偿器的性能。在本文中，XPolM的研究进行了回顾，独特的模拟XPolM的存在下走离，并证明了一些陷阱，在这样的模拟数据流的选择。然后，作者讨论了XPolM如何影响PMD和PMD引起的中断概率（OP）在光纤通信系统中，通过提供分析公式的OP有和没有XPolM。最后，通过给出当XPolM降低PMD补偿系统时的简单经验法则，将XPolM和PMD补偿联系在一起，并且讨论了对XPolM鲁棒的PMD抑制方法
It is well known that cross-phase-modulation-induced polarization rotation, cross-polarization modulation (XPolM), significantly degrades the performance of polarization-mode-dispersion (PMD) compensators. In this paper, the research on XPolM is reviewed, unique simulations of XPolM in the presence of walk off are presented, and some pitfalls are demonstrated with respect to choice of data streams in such simulations. Then, the authors discuss how XPolM affects PMD and PMD-induced outage probabilities (OP) in fiber-communication systems by providing analytical formulas for the OP with and without XPolM. Finally, the XPolM and PMD compensation are tied together by giving simple rules of thumb for when XPolM degrades PMD compensated systems, and PMD mitigation methods that are robust to XPolM are discussed
