Principle of Light Refraction in Optical Fiber Communication

The principle of fiber optic operation is based on Snell's law, which describes the phenomenon of light refraction when passing through the boundary between two mediums with different refractive indices. It is represented as − $$n = frac {c} {v}$$ Where, c = the speed of light in free space = 3 × 10 8m/s v = the speed of light in di-electric or non-conducting material. Optical fibers are thin glass rods that use the properties of light reflection and refraction to transmit data over long distances. First, the light-carrying core. Next, the cladding, and finally, the protective outer coating (also known as the jacket).  Higher bandwidth (extremely high data transfer rate).
