Paper Abstract

The theoretical model of DOP degraded by PMD is presented, with which one can analyze and maximize DOP directly from two factors, the magnitude and the direction of the PMD vector. According to this, one method to counteract PMD of the link is adjusting the compensating vector’s magnitude to achieve a zero-magnitude total PMD vector in the system, another is changing the vector’s direction adaptively to make the input signal align with the total PMD vector. Further, the NRZ signal DOP property degraded by PMD and the system’s BER against the change of PMD are obtained in the first experiment, also, the PMD compensation performance-degradation as the scrambling rate is increased is studied in the second experiment, in which it is concluded that the scrambling rate of polarization state has an important impact on a reliable, repeatable PMD compensation in a reasonably short time.
