-Digital fiber optic communication systems address modulation and detection methods for high spectral efficiency and cogency against transmission impairments and are an inherent part of modern communication systems. This paper outlines the design of an open-source tool to perform optical fiber experiments on MATLAB, promoting a greater understanding of optical fiber communication. The tool can be extended by adding experiments. Setting up optical communication systems may be expensive, making its installation in educational institutes unlikely. This tool provides a free alternative to deliver a similar experience to students, enabling possible widespread learning of optical systems in educational institutions. The proposed objective of the project is to design and analyze the simulation model of various modes of optical fiber communication systems using MATLAB and visualize and interact with it using Graphical User Interfaces.
