Fiber optic cable definition

A fiber optic cable is a flexible, high-speed data transmission medium, transparent fiber made by drawing plastic or glass to a diameter slightly thicker than that of a human hair. It is a high-speed data transmission medium.

Optical fiber cable is generally used as a means to transmit light between the two ends of the fiber and find wide usage in fiber optic communication. Digital data is transmitted through the cable via the rapid pulses of light. The receiving end of fiber optic transmission translates the light pulses into binary values, which can be read by a computer. Color fiber is spliced to ensure continuity of color codes throughout a cable run.


Since fiber optic cable provides fast transfer speed and large bandwidth, They are used for a large part of the internet backbone. For example, most transatlantic telecommunication cables between the U.S and Europe are fiber optic. In recent years, fiber optic technology has become increasingly popular for local internet connection as well. 
  • Fiber optic cable can be used as a medium for computer networking and telecommunication because it is flexible and can be bundled as cables
  • It also is used in telephone, military and space application
  • It can be used an easy, economical and attractive solution for a lighting project
  • It can be used to transmit power using a photovoltaic cell to convert the light into electricity.
