needs of communication systems, it is imperative for network builders and system users to update the deployed Single-Mode Optical Fiber System or lay new high-capacity systems. In this case, the restriction on the system performance of PMD and chromium dispersion must be considered. To better control and reduce the impact and limitations on system performance, researchers have begun an attempt to compensat
