Abstract

We report our theoretical analysis on polarization mode dispersion (PMD) tolerance of the return-to-zero transmission system under error-free [bit error rate (BER) ≤ 10-12] conditions. The results show that the tolerable PMD cannot be further enhanced by increasing the receiver power margin when forward error correction is used. The investigation also reveals that optimal receiver bandwidth for minimum BER should be increased accordingly when the accumulated PMD is increased. By designing the receiving filter with adaptive bandwidth, the acceptable average differential group delay can be improved by up to 2% of the bit interval.
