Abstract

The invention discloses a current correction method of an optical module. The method includes: obtaining an original temperature lookup table of the optical module and a plurality of bias current adjustment values ​​within a preset temperature range; performing calculations according to the plurality of bias current adjustment values ​​and preset calculation formulas to obtain corresponding correction values, And correct the original temperature lookup table according to the correction value. The invention also discloses a current correction device of the optical module and a computer-readable storage medium. The present invention can implement and provide a method for correcting the temperature lookup table of the optical module, so as to ensure that the optical module is within a certain high temperature range, and also enable the optical module to load a suitable bias current on the laser, so that the extinction ratio of the optical module is stable within a certain range.

Description

technical field [0001] The present invention relates to the technical field of optical modules, in particular to a current correction method and device for an optical module and a computer-readable storage medium. Background technique [0002] The full name of the optical module is the optical transceiver module. It is the core device in optical communication and can complete the optical-electrical / electrical-optical conversion process of optical signals. It is composed of optoelectronic devices, functional circuits and optical interfaces. Among them, the optoelectronic devices Including receiving and transmitting two parts. Simply put, the receiving part is responsible for converting optical signals into electrical signals, and the transmitting part converts electrical signals into optical signals. During the optical-electrical / electrical-optical conversion process, as the temperature rises, the optical module needs to load the driving current to the internal laser through...
