Abstract

Polarization Mode Dispersion and Polarization Dependent Loss are among the most important fiber impairments that induce errors and limit the overall system performance. In this paper, Levenberg-Marquardt Training Algorithm is proposed to mitigate the pulse deformation induced by Polarization Mode Dispersion and Polarization Dependent Loss. Reduction in output waveform distortion can be achieved by choosing appropriate states of polarization. Results show circularly polarized positive chirped super-gaussian input signal giving higher compression factor compared to linearly polarized signal. However, an improvement in compression ratio is achieved using Levenberg-Marquardt Algorithm. Since it is the fastest technique and gives accurate solution, it is used for PMD, PDL related problems..
