Optical Fiber Overview

Optical fibre Principle: Total Internal Reflection Optical fibres rely on total internal reflection for their operation. An optical fibre is an extremely thin cylindrical structure of high-quality glass. Light/infrared getting in at one end undergoes repeated total internal reflection and emerges at the other end. It consists mainly 3 parts- Core Cladding Jacket Optical fiber uses the optical principle of “total internal reflection” to capture the light transmitted in an optical fiber and confine the light to the core of the fiber. An optical fiber is comprised of a light-carrying core in the center, surrounded by a cladding that acts to traps light in the core. Glass fiber is covered by a plastic buffer coating that protects it from the environment and allows easy handling for splicing or termination.
