Optical module shell temperature monitoring method and device

Abstract

The invention discloses an optical module shell temperature monitoring method and device for improving the monitoring accuracy of the shell temperature of an optical module in each temperature range. The method comprises a step of obtaining a driving chip temperature sampling value when a condition that a first output value is in a low temperature threshold interval is determined according to a first output value of optical module shell temperature, a step of determining the second output value of the optical module shell temperature according to the linear relationship satisfied by the driving chip temperature sampling value and the optical module shell temperature, a step of obtaining a control chip temperature sampling value when a condition that the second output value is in a high temperature threshold interval is determined according to the second output value of the optical module shell temperature, and a step of determining the third output value of the optical module shell temperature according to the linear relationship satisfied by the control chip temperature sampling value and the optical module shell temperature. Different temperature sampling sources are selected to monitor the optical module shell temperature in different temperature ranges, and the monitoring accuracy of the optical module shell temperature in each temperature range is improved.
