Abstract :
We show a novel higher order polarization-mode dispersion (PMD) mitigation technique for a preamplified system based on narrow optical bandwidth filtering of the signal. Reducing the signal bandwidth results in increased signal immunity against higher order PMD distortions. The method is theoretically explained and experimentally verified.
