摘要 首先阐述了光纤中极化相关损耗(PDL)的基本概念,然后着重分析了极化相关损耗对系统偏振模色散(PMD)产生的影响,最后比较了测量极化相关损耗的不同方法的适用条件及性能差异。 This article first demonstrates the principle of PDL. And then it emphasizes the influence of PMD on the performance of optical transmission systems in the presence of PDL. At last compares different PDL measurement methods.
