These cables are used mainly for digital audio connections between devices. A 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. The optical fiber elements are typically. A fiber optic cable consists of five basic components: the core, the cladding, the coating, the strengthening fibers, and the cable jacket. This innovation made it possible to send light messages effectively over large distances. Larger core sizes allow a larger amount of light, or a larger beam diameter, to enter the fiber. Understanding the components within a fiber optic cable enables.
