OPTICAL FIBER

An Optical Fiber (or Fiber) is a glass or plastic fiber that carries light along its length.

Optical Fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications.

Fibers are used instead of metal wires because signals travel along them with low loss.
