Abstract
An optical communications circuit has a communications light signal source and a heat pump coupled to cool the signal source. A controller monitors a current and a temperature of the signal source, and regulates the temperature. The controller updates a heat pump control limit parameter for the heat pump, based on the monitored current. Other embodiments are also described and claimed.
