![]() ![]() Specially designed fibers are also used for a variety of other applications, such as fiber optic sensors and fiber lasers. Fibers are also used for illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Fibers are used instead of metal wires because signals travel along them with less loss in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer. Such fibers find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. ![]() A bundle of optical fibers A TOSLINK fiber optic audio cable with red light shone in one endĪn optical fiber, or optical fibre in Commonwealth English, is a flexible glass or plastic fiber that can transmit light from one end to the other. ![]()
