Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a transmitting and receiving device for optical fiber communication. Background technique [0002] Communication is realized by electricity, while optical communication is realized by using light as an information carrier. The so-called optical fiber communication is used to transmit and carry information to achieve the purpose of communication. To make light waves a carrier of information, it must be For this, the information is detected from the light wave at the receiving end. [0003] At present, the scope of use of optical fiber communication is increasing, and the information of the carrier is becoming more and more complex. The design of the traditional optical fiber communication transmitting and receiving device gradually presents some problems in the face of the rapid development of the information age. When there is too much carrier information, it ...
