Fiber optics is a technology that uses thin, flexible glass or plastic fibers to transmit light. The fibers are arranged in a bundle, each about the thickness of human hair.
Light travels through fiber optic cables by bouncing off the walls of the individual fibers. This allows information to be transmitted at high speeds with very little loss of signal strength. Fiber optic cables are used for long-distance telephone calls, cable TV, and high-speed internet connections.
Fiber optics has several advantages over other types of communication systems. For example, it is less expensive than copper wire, can carry more information than copper wire, and is not susceptible to interference from electromagnetic fields.
