Abstract

The invention relates to a high-speed fiber communication circuit. The high-speed fiber communication circuit comprises a sending circuit and a receiving circuit which are connected through fibers. The sending circuit comprises a driving circuit and a sender U2, external input signals are accessed through the input end of the driving circuit, the output end of the driving circuit is connected with the input end of the sender U2, and the output end of the sender U2 is connected with the input end of the receiving circuit; and the receiving circuit comprises a receiver U3, the input end of the receiver U3 is in communicating connection with the output end of the sender U2 through the fibers, and the output end of the receiver U3 outputs signals outwards. The high-speed fiber communication circuit is simple in circuit structure, high in data transmission rate, wide in transmission frequency bandwidth, high in anti-interference performance, small in signal attenuation, low in cost, high in stability and low in distortion, thereby being quite suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a high-speed optical fiber communication circuit. Background technique [0002] As one of the main pillars of modern communication, optical fiber communication has occupied a pivotal position in modern telecommunication networks. Optical fiber communication is a communication method that uses light waves as a carrier and optical fiber as a transmission medium to transmit information from one place to another. It is called "wired" optical communication. Today, optical fiber is far superior to cable and microwave communication transmission due to its transmission frequency bandwidth, high anti-interference and low signal attenuation. However, there are problems in the application process that the transmission is not easy and the cost of sending and receiving is high. Contents of the invention [0003] The technical problem to be solved by the present inventi...
