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会对系统偏振模色散(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。
Firstly, the basic concept of polarization-dependent loss (PDL) in optical fiber is expounded. Then, the influence of polarization dependent loss on PMD will be analyzed emphatically. Finally, different methods to measure polarization-dependent loss will be compared Conditions and performance differences.
