介绍了基于泰勒展开的偏振模色散（PMD）算符表示的PMD均衡器的理论基础。推导了偏振模色散均衡器的两种结构形式，即对角化算子的逆和延迟时间差补偿。一种是利用四分之一波长相位板的物理旋转的类型。另一种是使用可变移相器的类型，适用于PLC集成。通过对波形比较算法的仿真，发现由于光路的对称性和周期性，存在多个等效最优点。简要讨论了在第一、第二偏振模色散均衡电路与两个不同偏振态变换器级联的情况下的二阶偏振模色散均衡。
We introduce a theoretical basis of polarization mode dispersion (PMD) equalizers based on the operator representation of PMD using Taylor's expansion. The two types of configuration of PMD equalizers are derived as the inverse of diagonalization operators and delay time difference compensation. One is a type using physical rotation of quarter wave phase plates. The other is a type using variable phase shifters suitable for PLC integration. Waveform comparison algorithm was simulated to show the existence of multiple equivalent optimum points due to the symmetry and periodicity of optical circuits. The second order PMD equalization is discussed briefly on the case of cascading the first and the second PMD equalizing circuits with two different polarization state converters.
