Resource Overview

This study focuses on electrical domain equalization techniques for overcoming PMD (Polarization Mode Dispersion) effects in optical fiber communication systems. We developed comprehensive models of electrical equalizers and conducted simulation experiments to identify optimal structures for PMD compensation, incorporating digital signal processing algorithms and adaptive filtering implementations.

Detailed Documentation

In this document, we conduct an in-depth investigation of a key technology in optical fiber communication systems: electrical domain equalization techniques for mitigating PMD effects. We designed sophisticated models of electrical equalizers and performed detailed simulation experiments using MATLAB/Simulink environments. Through these simulations employing adaptive algorithms such as LMS (Least Mean Squares) and RLS (Recursive Least Squares), we successfully identified an optimized electrical equalizer structure that effectively compensates for PMD-induced signal distortion. This research holds significant importance for enhancing the performance of optical fiber communication systems and provides practical implementation solutions, including real-time tap weight adaptation and frequency domain equalization approaches, to address challenges posed by PMD effects.
