Performance Optimization of 120 Gbps–120 GHz Hybrid MDM-FSO Utilizing Non-Coherent Modified Duobinary Modulations for Optical Wireless Distributed Networks
Source abstract
Abstract
This study proposes optimizing the performance of free space optic signal transmission using spatial division multiplexing. The research uses different modified duobinary modulation schemes to model and optimize three hybrid mode division multiplexing-free-space optical (MDM-FSO) channels, each operating at 40 Gb/s–40 GHz. The study also includes the parametric optimization of various components to enhance system performance. The findings are significant for achieving high data rate links for backhaul solutions and improving bandwidth for future MDM-based wireless distributed networks. The research shows that employing three linearly polarized modes as data transmission channels with direct detection can be effective. Additionally, it is discovered that adjusting the bias voltages of the two LiNbO3 modulators can improve power sharing between the modes, thereby mitigating the power penalty.
