A Comprehensive Analysis of Four Channel CWDM Network System

Abstract

Growth of optical fiber communication has led to an increased demand for high bandwidth and long-distance transmission capabilities. In response, telecommunication companies are using DWDM network system is able to satisfy the demand, though this approach is often costly for customers. As an alternative, the CWDM network system has been proposed to provide a lower cost solution for high bandwidth transmission. The proposed study evaluates the effectiveness of transmitting various bandwidths for each channel in a 4-channel CWDM system using Opti System software. The study assesses the system's performance by measuring the extinction ratio and the separation of transmitter and receiver up to a fiber span of 100 km. This research focuses on applications that require shorter distances and where cost is a critical factor. The outcomes of this research can be used to improve the design and functionality of CWDM systems by illuminating their strengths and weaknesses. The usage of CWDM technology offers a cost-effective solution for telecommunication companies to meet the increasing demand for high bandwidth transmission while also providing a lower cost option for customers.
