Description

technical field [0001] The invention relates to the technical field of communication, in particular to a fast detection device for on-off optical fiber. Background technique [0002] An optical fiber (optic fiber) is a fiber made of glass or plastic that acts as a means of transmitting light. The principle of transmission is 'total reflection of light'. The tiny fiber is encapsulated in a plastic sheath that allows it to be bent without breaking. Usually, the transmitting device at one end of the fiber uses a light emitting diode (LED) or a laser beam to transmit light pulses to the fiber, and the receiving device at the other end of the fiber uses a photosensitive element to detect the pulse. In daily life, optical fibers are used for long-distance information transmission because the transmission loss of light in optical fibers is much lower than that of electricity in wires. Most optical fibers are coated with several layers of protective structures before use, and the...
