Answer Details
Optical fibers are thin, transparent fibers made of high-quality glass or plastic that transmit light signals over long distances by the principle of total internal reflection. When light travels through the fiber, it reflects off the walls of the fiber due to the phenomenon of refraction, which allows the light to propagate over long distances without much attenuation. Hence, the operation of an optical fiber is based on the principle of refraction of light.
