Abstract

The invention discloses a method and device for monitoring the service life of an optical module laser, belonging to the technical field of optical communication. The method includes: obtaining the current temperature, current driving current and current emission optical power of the optical module laser; , the current driving current and the current emission optical power determine the current luminous efficiency of the optical module laser; compare the current luminous efficiency of the optical module laser with the reference luminous efficiency of the optical module laser, and determine the The lifetime of the optical module laser. This makes the life judgment more accurate, further improves the reliability of life judgment, enables the module to be fully used, and also reduces the probability of communication interruption caused by the short life of the optical module.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a method, a device, a computer device and a storage medium for monitoring the service life of an optical module laser. Background technique [0002] At present, the method of monitoring the life of optical module lasers in the optical module industry is based on the alarm method of the driving current threshold of the optical module laser, while the telecom equipment manufacturers judge based on the current driving current of the optical module laser, but these methods have their limitations. The optical module laser inside the optical module will only generate laser light when the driving current is greater than a certain threshold. The output optical power is different with different driving currents. The temperature has a great influence on the relationship between optical power and driving current. It is difficult to use a driving current to measure the life of ...
