Paper Abstract

The optimal length of the fixed delay line (FDL) for a one-stage optical polarization mode dispersion (PMD) compensator with two degrees of freedom (DOF) is investigated for a 40 Gbit/s NRZ optical fiber transmission system by implementing genetic algorithm in the logic-control unit. It is found that there exists an optimal length of FDL for such an optical PMD compensator (PMDC), and the optimal length of the FDL is equal to the PMD value of the preceding transmission fiber to be compensated for. Such an optimized one-stage PMDC with a fixed delay line can achieve a close performance to that of a one-stage PMDC with a variable delay line.
