Abstract

The invention relates to the technical field of optical communication and particularly relates to an optical module temperature calibration method and device. The method comprises steps that the temperature of a specified temperature measurement area of an to-be-tested optical module is measured in real time through a multi-temperature sensor array in a temperature measurement module; the averagetemperature is calculated according to measured temperature values at every preset time, and whether the to-be-tested optical module enters a temperature stable state is determined; the reported temperature of the to-be-tested optical module is calibrated through the average temperature after stabilization; whether difference between the calibrated reported temperature and the stabilized average temperature satisfies a specified value is determined, if yes, temperature calibration is successful, if not, re-calibration is performed. The method is advantaged in that operation is simple, automatic calibration of the reported temperature of the optical module can be quickly realized, the actual temperature of the optical module can be accurately reflected through the reported temperature, interference of human factors is reduced, and thereby accuracy and reliability of the reported temperature of the optical module are improved.

Description

【Technical field】 [0001] The invention relates to the technical field of optical communication, in particular to a method and device for calibrating the temperature of an optical module. 【Background technique】 [0002] By looking at the protocols of various types of optical modules, it can be found that the protocols have relatively strict regulations on the reported temperature of the optical module and the actual CASE temperature (that is, the temperature on the surface of the package shell), and the temperature difference between the two is only allowed within the full temperature range. Within ±3°C; it can be seen that the accuracy of temperature plays an important role in the optical module. At present, in the field of optical modules, the common method of temperature calibration is to use a spot thermometer to paste the twisted pair on the surface of the module to read the temperature, and then manually write the calibration value to calibrate. However, the accuracy o...
