Abstract
A system and method of minimizing the amount of power that is used by an optoelectronic module is disclosed. The system uses a thermoelectric cooler (TEC) to maintain a case temperature of the module at about 50° C. This allows the TEC to operate in the much more efficient heating mode, thus minimizing the amount of current being used to maintain the module temperature. The method includes the steps of determining a temperature range and operating temperature for an optoelectronic module, such that a maximum current level is not exceeded. In one exemplary embodiment, an operating temperature of about 50° C. with a temperature range of from about −5° C. to about 75° C. allows a maximum current of about 300 mA.
