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 fibers are used in telecommunications to transmit data over long distances.
They are also used in medical equipment such as endoscopes and laser surgery tools.
Optical fibers have a higher bandwidth than traditional copper wires, allowing for faster data transmission.
They are immune to electromagnetic interference and can transmit signals over longer distances without signal degradation.
Optical fibers are made of a core, cladding, and protective coating to prevent damage.
They work by using total internal reflection to keep the light signal within the core of the fiber.
