Reduction of four wave mixing efficiency in DWDM systems using optimal PMD

Abstract

Investigation of polarization mode dispersion (PMD) effect on the performance of nonlinear optical transmission system, in terms of bit error rate and mixing efficiency was conducted. It shows an improvement in the system performance, in the presence of PMD. The effect of PMD was considered for different link lengths and the resulting effects on system performance were studied. It was demonstrated that fiber nonlinearities can be reduced in the presence of optimal amount of PMD, and have achieved average reduction in four wave mixing efficiency of 6.9 dB within the interval of − 18 to 4 dBm launch power, and maximum of 14.5 dB at 2 dBm launch power for an 80 Gbps non-return-to-zero dense wavelength division multiplexing system. OptiSystem software was used for the simulation.
