Fiber optics is a technology that transmits data through thin glass or plastic fibers using light signals. It is widely used in communication channels such as telephone networks, television systems, and the Internet. The technology works by converting electrical signals into light at the input side and then converting them back to electrical signals at the output side. Fiber optic cables consist of three main components: a core that carries light signals, cladding that reflects light back to the core preventing signal loss, and a protective coating that shields the cable from environmental damage.
