Abstract
The case temperature measurement device for an optoelectronic transceiver includes a case with at least one thermally conductive wall, at least one optical component at least partially disposed within the case, circuitry electrically coupled to the optical component. The circuitry includes a temperature sensor coupled to the circuitry. The case temperature measurement device also includes at least one protrusion formed on the wall of the case of the optoelectronic transceiver. The protrusion is thermally coupled to temperature sensor via a thermal pad. A method for estimating case temperature of the optoelectronic transceiver based on an internal temperature measurement and knowledge of the relationship between the measured internal temperature and the actual case temperature, and compensating for the effects of variable heat sources within the transceiver upon this estimate.
