An optical fiber, which is a shorthand for an optical fiber, is a light conducting tool that is achieved by the principle of total reflection of light in glass or plastic made of glass. The optical fiber was invented by the former president of the Chinese University of Hong Kong.
The fine fiber is encapsulated in a plastic sheath so that it can bend without breaking. In general, the transmitting means at one end of the optical fiber uses a light emitting diode (LED) or a laser beam to transmit the optical pulse to the optical fiber, and the receiving means at the other end of the optical fiber uses the photosensitive element to detect the pulse. In everyday life, as the transmission loss of light in the optical fiber is much lower than the loss of electrical conduction in the wire, the fiber is used for long distance information transmission.
