What is optical fiber

Question

Accepted Answer

Optical fiber is a thin, flexible, transparent fiber made of glass or plastic that can transmit light signals over long distances.

Optical fiber is used in telecommunications to transmit data over long distances.
It works by transmitting light signals through the fiber, which bounce off the walls of the fiber and travel to the other end.
Optical fiber is faster and more reliable than traditional copper wire.
It is also used in medical equipment, military technology, and industrial applications.
There are two types of optical fiber: single-mode and multi-mode.

Accepted Answer

Optical fibres works on the principle of total internal reflection. When light ray strikes at the internal surface of optical fibre cable called such that incidence angle is greater than critical angle, then incident light ray reflects in the same medium and this phenomenon repeatsOptical fibres works on the principle of total internal reflection.
