1. An optical module apparatus, comprising:

  • one or more semiconductor light sources to emit light;

    one or more photodetectors to detect the light emitted from the one or more semiconductor light sources;

    one or more optical fibers;

    optics to optically couple light emitted from the one or more semiconductor light sources to the one or more optical fibers and from the optical fibers to the one or more photodetectors;

    a laser diode driver communicatively connected to the one or more semiconductor light sources to drive the one or more semiconductor light sources;

    a temperature monitor having an output and configured to generate an output indicative of a temperature of the optical module apparatus;

    a voltage regulator configured to generate output voltages and coupled to the laser diode driver to provide a supply voltage to the laser diode drive to drive the one or more semiconductor light sources, wherein the supply voltage to the laser diode drive is included in the output voltages;

    voltage regulator control electronics configured to adjust the output voltages of the voltage regulator with respect to the output of the temperature monitor; and

    a microcontroller including an input to receive the output of the temperature monitor and configured to provide a control input to the voltage regulator control electronics based at least in part on the received output of the temperature monitor.
