optical fiber

A flexible transparent fiber, usually made of glass or plastic, through which light can be reflected to transmit images or data from one end to the other. Unlike other communications cables, which are made of metal and transmit data as fluctuating electric currents, optical fibers transmit data as pulses of light. See more at fiber optics.
