A Fiber Optic Cable is a type of network cable that is made up of strands of glass fibers that are enclosed in an insulated casing. It is made for long-distance, high-speed data networking and telecommunications. Fiber optic lines have a greater bandwidth than conventional lines and can carry data across greater distances. Most of the world's internet, cable television, and telephone services are supported by fiber optic connections. One or more strands of glass, each fairly thicker than a human hair, make up a Fiber Optic Cable. The core is the part of each strand that offers a channel for light to go through.
