Fibre-optic communication involves transmitting a signal as light, converting electrical signals to optical signals at the transmitter end and reversing the process at the receiver end. Light acts as a carrier wave and can be modulated to carry information. The electromagnetic energy travels through. Optical Fiber Communication (OFC) revolutionizes modern telecommunications, enabling rapid data transfer across long distances with minimal signal loss. This comprehensive review explores OFC's historical evolution, core principles, components, and versatile applications. Optical fiber wave guides- Introduction, Ray theory t ansmission, Total Interna ERS: Attenuation, Absorption, Scattering and Bending losses, Core and Cladding losses. Total internal reflection (critical angle, using Snell's law). Higher bandwidth (extremely high data transfer rate).
