The transmission principle is total reflection of light, and a tiny optical fiber is encapsulated in a plastic sheath so that it can be bent without breaking. In general, a transmitting device at one end of an optical fiber transmits an optical pulse to the optical fiber using a light emitting diode or a laser beam, and a receiving device at the other end of the optical fiber detects the pulse using a photosensitive element, and in daily life, since the conduction loss of light in the optical fiber is much lower than the conduction loss of electricity in an electric wire, the optical fiber is used for long distance information transmission, and generally, two terms of the optical fiber and the optical cable are confused. Most optical fibers must be covered with several layers of protective structures before use, and the covered cable is called an optical cable.
