Abstract

Using the degree of polarization as feedback signal to detect the polarization mode dispersion (PMD) variation in the fiber links, an experiment of dynamic adaptive PMD compensation in 4×10 Gb/s optical time-division multiplexed (OTDM) transmission system is reported. The PMD compensator consists of polarization controller and variable delay line with four degrees of freedom. Based on the variable step-size peak search algorithm, the performance of the PMD compensator is assessed in the eye pattern of a received signal. It is shown that the maximum compensated DGD is 25 ps, i.e. one bit period, and the compensation time can be less than 50 ms.
