![]() Individual coated fibers (or fibers formed into ribbons or bundles) then have a tough resin buffer layer or core tube(s) extruded around them to form the cable core. ![]() This coating protects the fiber from damage but does not contribute to its optical waveguide properties. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. Different types of cable are used for optical communication in different applications, for example long-distance telecommunication or providing a high-speed data connection between different parts of a building. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. These cables are used mainly for digital audio connections between devices.Ī fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. Cable assembly containing one or more optical fibers that are used to carry lightĪ TOSLINK optical fiber cable with a clear jacket. ![]()
