optical fiber

n.
A flexible transparent fiber of extremely pure glass or plastic, generally between 10 and 200 microns in diameter, through which light can be transmitted by successive internal reflections, commonly used in telecommunications.

fi′ber op′tics

or fi′ber•op′tics,


n.
the technology of sending computer data, video and voice signals, etc., through laser-generated light carried in bundles of ultrapure, transparent fiber (optical fiber) whose refraction properties allow the light to be transmitted around curves.

fi`ber•op′tic, adj.

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.
