Abstract
A laser transmission system includes: a modulation module, a voltage-current conversion module, an electro-optic conversion module, an optic-electro conversion module, and a control module. The modulation module is configured to modulate an input voltage, and output a first voltage. An average value of the first voltage within a first duration is 0. The voltage-current conversion module is configured to output a first current based on the first voltage. The electro-optic conversion module is configured to output an optical signal corresponding to the first current. The optic-electro conversion module is configured to receive the optical signal from the analog optical fiber, and output a second voltage based on the optical signal. The control module is configured to determine an average value of the second voltage, and determine an electro-optic conversion coefficient of the electro-optic conversion module based on the average value of the second voltage.
