An optical transceiver module (Fig. 3) having digital control of laser curre nt peaking is disclosed. The optical transceiver module comprises a controller and integrated postamplifier/laser driver (Fig. 3), which are included on a printed circuit board disposed in the module. Transmitting (14) and receivin g optical sub-assemblies (47) are also disposed in the module. A digital signa l interface (50B) interconnects the controller with the integrated postamplifier/laser driver. Digital control signals produced by the controll er 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 (48) responsible for governing the electrical current supplied to the laser of th e transmitting optical sub-assembly. The laser current is intermittently peake d by the control signal in order to hasten the transition from light to no-lig ht emission, thereby improving laser response and performance.
