Abstract
A signal transmission system includes a first laser signal transmission system, a second laser signal transmission system and a control module. The first laser signal transmission system includes an electric signal generation module, a first electro-optical conversion module and a first optical-electro conversion module. The electric signal generation module outputs a first current and a first voltage. The first electro-optical conversion module outputs a first optical signal. The first optical-electro conversion module outputs a second voltage. The second laser signal transmission system alternately inputs the first voltage and a calibration voltage and outputs a third voltage. The control module determines the first voltage based on the correspondence relationship between the calibration voltage and the third voltage and based on the third voltage, and determines a first electro-optical conversion coefficient based on a ratio of the first voltage to the second voltage.
