Adaptive PMD compensation using DPSO algorithm for high-speed optical fibre communication systems

Abstract

We proposed an adaptive PMD compensation scheme based on FPGA using DPSO algorithm. Stable polarization compensation for 43Gbit/s RZ-DQPSK transmission over 1200km was demonstrated with endless polarization scrambling. Excellent performance was accomplished utilizing our scheme in case of changing SOP and DGD in long-haul fibre link.
