Background

Optical fiber is a shorthand for optical fiber, a fiber made of glass or plastic, which can be used as a light conducting tool, and a fine optical fiber is enclosed in a plastic sheath so that it can be bent without breaking. Typically, a transmitter at one end of the fiber uses a light emitting diode or a beam of laser light to transmit a pulse of light to the fiber, and a receiver at the other end of the fiber uses a light sensitive element to detect the pulse. In daily life, optical fibers are used for long distance information transmission because the loss of light transmitted through optical fibers is much lower than the loss of electricity transmitted through electric wires. In general, the terms optical fiber and optical cable are to be confused. Most optical fibers must be covered by several layers of protective structures before use, and the covered cables are referred to as fiber optic cables. The protective layer and the insulating layer on the outer layer of the optical fiber can prevent the surrounding environment from damaging the optical fiber, such as water, fire, electric shock and the like. Optical fiber transmission, that is, data and signal transmission using optical fiber as a medium. The optical fiber can be used for transmitting analog signals and digital signals, and can meet the requirement of video transmission.
