A fiber optic cable consists of five basic components: the core, the cladding, the coating, the strengthening fibers, and the cable jacket. 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. An optical fiber cable is a complex structure designed to protect fragile glass fibers that transmit digital data using light signals. Fiber Core: A thin strand of glass or plastic, typically measured in microns, that is the primary.
