Principle of optical fiber communication
Oct 11, 2022| Principle of optical fiber communication
At the transmitting end, the transmitted information should first be converted into an electrical signal, and then modulated to the laser beam emitted by the laser, so that the intensity of light changes with the amplitude of the electrical signal, and is transmitted through the optical fiber through the principle of total reflection of light; At the receiving end, the optical fiber communication can be completed after the detector recognizes, converts and translates the optical signal.
Optical fiber communication principle: at the sending end, the transmitted information should first be converted into an electrical signal, and then modulated to the laser beam sent by the laser, so that the intensity of light changes with the amplitude of the electrical signal, and transmitted through the optical fiber through the principle of total reflection of light; At the receiving end, the optical fiber communication can be completed after the detector recognizes, converts and translates the optical signal. Optical fiber communication is a communication mode that uses light wave as information carrier and optical fiber as transmission medium. In principle, the basic material elements of optical fiber communication are optical fiber, light source and optical detector. In addition to classifying optical fibers according to manufacturing process, material composition and optical characteristics, optical fibers are often classified according to their applications, which can be divided into communication optical fibers and sensing optical fibers.
