Optical cables, also known as fiber optic cables or TOSLINK cables, use light to transmit audio and video signals from one device to another. Unlike traditional copper cables that rely on electrical signals, optical cables utilize the properties of light to carry data. Such fibers are widely used in fiber-optic communication, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than. An optic cable, or fiber optic cable, is a thin strand of glass or plastic that transmits data as pulses of light instead of electrical signals. Each strand is roughly the width of a human hair, yet a single fiber can carry hundreds of gigabits of data per second over distances that would cripple a.
