This project investigates the application of optical fibre communication in broadcast systems, focusing on its advantages over traditional methods like coaxial cables. The study explores the theoretical basis of optical fibre communication, including the operation of fibre optic cables, the components of a communication system (transmitter, receiver, light source, and detector), and the two main types of cables: single-mode and multimode. It delves into system design considerations such as optical power budgets, multiplexing techniques, and modulation methods like Pulse Code Modulation (PCM). The project examines the characteristics of optical fibre, including transmission windows, receiver sensitivity, and Bit Error Rate (BER). Furthermore, it highlights future trends such as Dense Wave Division Multiplexing (DWDM) and intelligent optical transmission networks, concluding that optical fibre communication is crucial across various sectors, particularly in telecommunications for transmitting cable television signals, internet, HDTV, and video-on-demand. The project references several sources to support its findings.
