    • 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.
    • 用于光电收发器的壳体温度测量装置包括具有至少一个导热壁的壳体,至少部分地设置在壳体内的至少一个光学部件,电耦合到光学部件。 电路包括耦合到电路的温度传感器。 壳体温度测量装置还包括形成在光电收发器的壳体的壁上的至少一个突起。 突起通过热垫热耦合到温度传感器。 一种用于基于内部温度测量估计光电收发器的壳体温度的方法,以及对所测量的内部温度与实际情况温度之间的关系的了解以及在该估计上补偿收发器内的可变热源的影响的方法。
