A fiber-optic cable, also known as an optical-fiber cable, is a cable that is one or more optical fibers that are used to carry light. The optical fiber elements (typically made of glass) are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. →
