This document discusses fiber optics, including its construction, working principles, applications, and benefits. Fiber optics uses glass or plastic strands to transmit data using pulses of light. It has a higher refractive index core surrounded by a lower refractive index cladding that allows total internal reflection to guide light long distances with minimal loss. Fiber optic networks have largely replaced copper networks for telecommunications and internet infrastructure due to their higher bandwidth, lower attenuation over longer distances, immunity to electromagnetic interference, and smaller size. Fiber optics is used widely in applications like telephone networks, internet, LANs, security systems, and sensors.
