Optical transceiver module temperature control device and optical transceiver module temperature control method

An optical transceiver module temperature control method, adapted to an optical transceiver module temperature control device, wherein the optical transceiver module temperature control device comprises a processor, a first temperature sensor, a printed circuit board assembly, an optical transceiver module and a temperature adjustment element, wherein the optical transceiver module temperature control method comprises:

• measuring an ambient temperature by the processor;
• measuring a temperature of the optical transceiver module by the first temperature sensor, wherein the optical transceiver module is disposed on a first side of the printed circuit board assembly, wherein the first temperature sensor is coupled to the processor and is disposed on a second side of the printed circuit board assembly;
• determining whether the ambient temperature or the temperature exceeds an operating temperature range to generate a temperature adjustment signal to the temperature adjustment element by the processor, wherein the temperature adjustment element is disposed on the second side of the printed circuit board assembly, and partially overlaps with respect to a position of the optical transceiver module, wherein the first side and the second side are located on different planes;
• and
• performing heat exchange with the printed circuit board assembly according to the temperature adjustment signal to adjust the temperature of the optical transceiver module into the operating temperature range by the temperature adjustment element.
