Abstract

The adaptive polarization mode dispersion (PMD) compensation in high-speed transmission system has become more and more necessary for the link PMD causing strong signal distortions. A dynamic adaptive PMD compensator in 40 Gb/s polar-multiplex differential quadrature phase shift keying (PM-DQPSK) system is reported. Experimental results show that the PMD compensator can track the average polarization state variation at 65 rad/s without any lost of the optimum tracking. The 1st-order PMD compensation is demonstrated experimentally, and the compensator can increase the maximal tolerable PMD value by 26 ps from 17 ps to 43 ps in an optical transmission system.
