Efficient DOP monitoring of WDM channels for simultaneous PMD compensation

We demonstrate averaged-DOP monitoring of WDM channels for simultaneous PMD compensation. Using a single PMD compensator for four 10 Gbit/s WDM channels, we achieve a significant power penalty reduction of more than 10 and 3 dB for NRZ and RZ, respectively, in the worst-case of first-order PMD emulation. The 2% worst-case performance of the averaged-BER is improved by two orders of magnitude and averaged-DOP is enhanced by 20%.
