Definition of "Optical Fiber" |
A filament of transparent dielectric material, usually glass or plastic, and usually circular in cross section, that guides light. / A technology that uses glass or plastic threads fibers to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. / An optical fiber (or optical fibre) is a flexible, transparent fiber made of extruded glass (silica) or plastic, slightly thicker than a human hair. It can function as a waveguide, or “light pipe”, to transmit light between the two ends of the fiber. Power over Fiber optic cables can also work to deliver an electric current for low-power electric devices. / Comit Europeene de Normalisation Electrotechnique Internal Regulations, Part 2, states that the EN carries with it the obligation to be implemented at national level by being given the status of a national standard and by withdrawal of any conflicting national standard. / a single optical transmission fiber usually comprised of a cylindrical core (5–100 mm diameter) in which the light is guided of higher index of refraction surrounded concentrically by a cladding (125– 250 mm diameter) with a lower index of refraction. More properly defined as an optical waveguide. Some optical fibers may have multiple concentric cores and/or claddings. Optical fibers made be of all glass, all plastic, or a combination of glass core and plastic cladding construction. Optical glass fibers may be silica- or fluoride-based glass. |
