Performance Analysis of Dense Wavelength Division Multiplexing System Based on Free Space Optics Communication

Abstract

This study reported the performance evaluation of various distributors and exchange elements configurations in the optical fiber communication system. With the increasing demand for high-speed data transfer, Dense Wavelength Division Multiplexing (DWDM) technology has become an attractive solution for optical communication systems. This paper presents the performance analysis of a DWDM-FSO-based on Free space optical communication system. The system consists of multiple channels, each transmitting data at a different wavelength, which are combined into a single optical fiber using a multiplexer. A demultiplexer separates the channels at the receiving end, and each channel's data is recovered separately. We analyze the performance of the system by measuring its bit error rate (BER) and Q-Factor (Quality Factor) under different channel. We also examine how varying the channel number affects the system's performance. Our results demonstrate that the proposed system can achieve high data rates and excellent performance with low BER and high Q-Factor (Quality Factor), making it a promising compressional evaluation for high-speed optical communication systems
