发明名称 Control of peaking of laser driver current to improve eye quality
摘要 An optical transceiver module having digital control of laser current peaking is disclosed. The optical transceiver module comprises a controller and integrated post-amplifier/laser driver, which are included on a printed circuit board disposed in the module. Transmitting and receiving optical sub-assemblies are also disposed in the module. A digital signal interface interconnects the controller with the integrated post-amplifier/laser driver. Digital control signals produced by the controller are transmitted via the digital signal interface to the integrated post-amplifier/laser driver, where they are converted to analog control signals. The analog control signals are forwarded to control components responsible for governing the electrical current supplied to the laser of the transmitting optical sub-assembly. The laser current is intermittently peaked by the control signal in order to hasten the transition from light to no-light emission, thereby improving laser response and performance.
