Optical fiber
An optical fiber (or fibre) is a glass or plastic fiber designed to guide
light along its length. Fiber optics is the overlap of
applied science and
engineering concerned with such optical fibers. Optical fibers are widely used in
fiber-optic communication, which permits transmission over longer distances and at higher data rates than other forms of wired and wireless communications. Fibers are used instead of metal wires because signals propagate along them with less loss, and they are immune to
electromagnetic interference. Optical fibers are also used to form
sensors, and in a variety of other applications.

optical fiber
Noun
1. a very thin fiber made of glass that functions as a waveguide for light; used in bundles to transmit images
(synonym) glass fiber, optical fibre, glass fibre
(hypernym) fiber, fibre
(part-holonym) fiber optic cable, fibre optic cable
optical fiber
A filament of transparent
dielectric material, usually
glass or plastic, and usually circular in cross section, that guides
light . (
188 ) Note 1: An optical fiber usually has a cylindrical
core surrounded by, and in intimate contact with, a
cladding of similar geometry. Note 2: The
refractive index of the core must be slightly higher than that of the cladding for the light to be guided by the fiber. Synonym lightguide.
