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.

Abstract: Improving the signal to noise ratio in an optical link involves either reducing the noise or increasing the RF power coupled into the optical link by lowing the voltage, Vπ, required to induce a phase change of π of the optical beam passing through the optical modulator. The present disclosure relates to methods and architectures for increasing the optical power through a link through providing one or more laser sources, additional modulators or photodiode receivers and dividing the optical power through these components so that none are overloaded.
