分析了PMD椭球的三个轴随PMD的变化规律,建立了以偏振度椭球的短轴作为PMD补偿的反馈信号的PMD补偿系统模型,并通过数值模拟对一阶和二阶PMD进行了补偿,结果表明采用这种方法能同时有效地补偿一阶及二阶PMD。
PMD ellipsoidal three-axis PMD variation law was analyzed, the PMD compensation system model was established, which used the minor axis of polarization ellipsoid as the PMD compensation signal, and the first and second order PMD were simulated by numerical simulation The results show that this method can effectively compensate the first order and the second order PMD.
