Optical fiber refers to the technology associated with data transmission using light pulses travelling along with a long fiber, usually made of plastic or glass. Transmission using fiber optic communication is preferred to use metal wires as signals are able to travel with less losses. Optical fibers are also unaffected by electromagnetic interference. The fiber optic cable uses the application of Total Internal Reflection of light.
The fibers are designed such that they facilitate the propagation of light along the optical fiber depending on the requirement of power and distance of transmission. A single mode fiber is used for long distance transmission while a multimode fiber is used for shorter distances. The outer cladding of optical fibers need better protection than metal wires.
