Abstract

The invention discloses an optical transmitter, which is applied to a photoelectric interconnection interface system and comprises an electric chip and an optical chip which are connected with each other. The electric chip comprises a driver module and a matching module. The driver module is used for generating a driving signal and transmitting the driving signal to the optical chip. The optical chip is used for modulating the optical signal according to the driving signal to obtain a modulation signal and outputting the modulation signal. The matching module is used for performing impedance matching on the driving signal output by the optical chip. The optical transmitter has the advantages that the device selection of the optical transmitter is not limited, and the impedance matching precision is high.

Description

technical field [0001] The invention relates to the technical field of photoelectric communication, in particular to an optical transmitter. Background technique [0002] Impedance matching is a part of microwave electronics. It is mainly used on transmission lines to achieve the purpose that all high-frequency microwave signals can be transmitted to the load point, and no signal will be reflected back to the source point, thereby improving energy efficiency. . [0003] In the design of the existing optoelectronic interconnection interface system, due to the continuous increase of the signal transmission rate, the impedance matching between the electric driver module and the optical module will directly affect the transmission effect and signal quality of high-speed signals. Therefore, in the design process of the electric driver module, it is often considered to design an impedance matching device (circuit) consistent with the characteristic impedance of the optical module...
