Fiber Optics

Refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic wire or fiber. Optical fiber carries much more information than conventional copper wire and is in general not subject to electromagnetic interference and the need to retransmit signals. The signal loss in a fiber optics system is usually smaller than in coaxial cables, and so optic fibers are often used to carry signals over extremely long distances.
