Enhanced Optical Communication Using VCSEL and FSO with Optical Amplifier and Filter Technologies

Problem Definition

From the literature survey conducted, it is evident that while free space optics (FSO) technology has shown great potential in the telecom industry due to its high data transfer capacity and cost-effectiveness, it faces significant limitations and challenges. The traditional FSO communication systems have been found to suffer from performance degradation caused by atmospheric and climatic factors, especially in long reach applications. Moreover, the susceptibility to noise when transmitting signals over longer distances has resulted in errors and decreased system performance. These obstacles highlight the need for advancements in FSO technology to overcome these limitations and improve overall system efficiency. Various researchers have proposed techniques to enhance the performance of FSO communication systems, aiming to address issues such as signal noise, signal strength amplification, and error reduction.

However, the existing literature indicates that these challenges persist and continue to hinder the optimal functioning of FSO systems. Therefore, there is a clear necessity for further research and development to innovate upon existing methods and develop a more robust and efficient FSO communication system that can effectively mitigate these shortcomings. This project seeks to build upon previous work and introduce novel enhancements that will eliminate noise, amplify signals, and improve overall system performance, particularly in long-distance communications.

This hybrid system aims to eliminate noise, amplify signal strength, and improve overall system performance, particularly in long-distance communications. By incorporating optical amplifiers and filters, the proposed method seeks to address the limitations of traditional FSO systems caused by atmospheric and climatic factors, signal noise, and errors over extended distances. The goal is to develop a more robust and efficient FSO communication system that can effectively mitigate these shortcomings and achieve reliable data transmission in the telecom industry.
