In this video, we demonstrate the practical experiment on Digital Link Characterization in Fiber Optic Communication using the Fibre Optic Digital Link Trainer Kit. Studying a 650mm fiber optic analog link and the relationship between input and received signals. A telephone line is such a system. For such systems, modems are used to convert the digital signals into an analog form suitable for transmission. A common medium used. The experiment aim of this experiment is to analyze the operation of Non-Return to Zero(NRZ), Return to Zero(RZ) and Pulse ration encoders and decoders. Construct a digital transmission system applying these data codes to optical transmitter and analyze the decoding of data through a fiber optic. This document outlines the setup and evaluation of an 850 nm fibre optic analog and digital transmission link. It details the objectives, apparatus, theoretical background, procedures for both analog and digital links, and includes prelab and postlab questions to enhance understanding of fibre. How Fiber Transmits Signals By Light (Grades K-12) This is a demonstration of how communications signals travel as pulses of light over fiber optics, creating a fiber optic telegraph that sends signals as light and can send Morse code.
