Background
Optical fiber communication is a communication mode that light is used as an information carrier and optical fiber is used as a transmission medium, firstly, an electric signal is converted into an optical signal, and then the optical signal is transmitted through the optical fiber, and belongs to one type of wired communication. The light is modulated to carry information. The optical fiber communication has the advantages of large transmission capacity, good confidentiality and the like. The optical transmitter converts the signal into optical signal suitable for transmission on optical fiber, the optical fiber circuit transmits the signal, and the optical receiver receives the optical signal, extracts information from the optical signal, converts the information into electric signal and finally obtains corresponding information such as voice, image, data and the like. When the switching is inevitably required to be realized in the optical fiber communication process, the signal loss phenomenon occurs in the signal switching process, the requirement on a cable adapter is higher in order to avoid the loss of the signal in the switching process, firstly, the signals cannot be connected in series, and the connector is well fixed and has insulation requirements and the like.
