An Adaptive Algorithm for Dynamic Polarization Mode Dispersion Compensation and Its Realization
动态偏振模色散补偿的自适应算法及实现

An adaptive algorithm for dynamical compensation of polarization mode dispersion (PMD) in optical transmission systems was proposed and realized in the experiment. It gives a good solution of global optimum searching in multi degree of freedom PMD compensation avoiding to be trapped in sub optima. The algorithm demonstrated itself a good characteristics and fast speed for global optimum searching and tracking in PMD compensation. The time used for global optimum searching is 78.77 ms and response tracking time is 15.75 ms. In addition, in order to apply it in real system, sampling and feedback control module, the core of the PMD compensation, is deeply analyzed.
