| Abstract: | An experiment of adaptive polarization mode dispersion compensation for optical communication systems was successfully realized. In the experiment,the power of specific frequency component was detected as PMD monitoring feedback signal. An artificial intelligence search algorithm, called particle swarm optimization (PSO), was adopted in the experiment. The compensated PMD value is up to 30 ps. Automatic tracking time is about 1 to 2 second. The quasi-real-time adaptive PMD compensation was realized. |
