Patent ID: 7668464

Claim:
An optical transceiver module, comprising: an optical transmitter assembly including a laser device capable of producing an optical signal in response to an electrical laser current; an optical receiver assembly; and a printed circuit board having disposed thereon: a controller capable of producing digital control signals; a laser driver capable of producing the electrical laser current for use by the laser device; means for digitally transmitting the digital control signals from the controller to the laser driver; at least one digital-to-analog converter in communication with the means for digitally transmitting, the at least one digital-to-analog signal converter configured to convert the digital control signals transmitted from the controller into analog control signals; and means for modifying the magnitude of the electrical laser current in response to the analog control signals, wherein: the means, in response to an analog control signal, peaks the electrical laser current such that a time to transition the laser from a first state, where the laser produces light, to a second state, where the laser produces no light, is relatively shorter than would be experienced without the electrical laser current peaking; and the electrical laser current peaking, when performed by the means, begins no sooner than initiation of the transition from the first state to the second state and is completed prior to attainment of the second state.
