Fiber Optics

Published February 2000

A means of transmitting data and communications in which light transmitted through thin glass fibers is intensity modulated by data signals. The use of fiber optics significantly reduces the large volume of wire or conductors (coaxial and twisted pair) normally used. The fiber optics method of transmitting information significantly increases transmission capacity and, correspondingly, reduces the size of communications conductors. Fiber optics requires the use of special source drivers and modems. Terminations and connections tend to be costly because fiber ends require special polishing.
