[0002] The optical module is composed of optoelectronic devices, functional circuits and optical interfaces, and the optoelectronic devices include two parts of emission and reception. In simple terms, the function of the optical module is photoelectric conversion, and the sending end converts electrical signals into optical signals, and the receiving end converts optical signals into electrical signals after transmission through the optical fiber.

[0003] The optical module is a high-power heating device currently applied in the communication industry, and according to the packaging form, common optical module products include SFP, SFP+, SFF and gigabit interface converter (GBIC).

[0004] However, the current traditional temperature detection and calibration method mainly uses workers to fix the temperature sensing thermocouple on the largest heating part of the optical module by using adhesive tape to test the temperature. This method has the following problems in practice: 1. The adhesive tape has poor reliability in fixing the temperature sensing thermocouple, resulting in incomplete contact between the temperature sensing thermocouple and the optical module. Or in high temperature conditions, the adhesive force of the adhesive tape is weakened, and even the temperature sensing thermocouple and the optical module are separated, thereby affecting the final test results. 2. Workers need to fix the temperature sensing thermocouple by using adhesive tape, which is more tedious, especially when the surface temperature of the optical module is not uniform, and the temperature measuring position needs to be replaced in real time, workers need to repeatedly operate and paste the adhesive tape, not only consuming energy, but also causing the adhesive force of the adhesive tape to be further weakened, greatly reducing the fixing reliability of the temperature sensing thermocouple, resulting in incomplete contact or even separation between the temperature sensing thermocouple and the optical module, and finally increasing the detection error.
