Fiber Optic Communication

Fiber optic communication technology is being used in more and more environmnets such as telecommunications, networking, data communications, industrial communication links, and medical communication links. More places are using fiber optics because of the increased bandwidth and improved length compared to copper networks. Fiber optic transmission devices are also called optoelectronic devices are coupled with optical fibers for data and signal transmission by converting optical signals into electronical signals and vice versa.

Fiber optic communication uses optical transmitters, optical recievers, optical fiber, and other components to transmit light signals through fiber. Fiber optic cables are made up of thin transparent fibers of glass or plastic enclosed by material with a lower index of refraction and transmit light throughout their length by reflections. Also, the fibers within the cables are protected by a polymer jacket. Fiber optics are becoming extremely popular in communications and industries.
