fiber used to transmit information: a fiber made of very pure glass or plastic that is used in modern communications systems to transmit information in the form of pulses of laser light. The core is usually of high refractive index and is enclosed in a sheath of lower refractive index, the light thus being transmitted by total internal reflection.
