CALIBRATION METHOD, APPARATUS AND DEVICE FOR COHERENT OPTICAL MODULE, AND COMPUTER READABLE STORAGE MEDIUM

A calibration method, apparatus and device for a coherent optical module, and a computer readable storage medium. The method comprises: obtaining a first curve relationship and a second curve relationship, wherein the first curve relationship represents the relationship between a power gain reporting voltage and a receiving end optical power within a receiving end optical power range corresponding to the coherent optical module, and the second curve relationship represents the relationship between a target setting voltage and the receiving end optical power within the receiving end optical power range corresponding to the coherent optical module; determining a first optical power on the basis of the first curve relationship and the second curve relationship, wherein the first optical power is used for dividing the receiving end optical power range into two ranges; and determining a calibration mode of the coherent optical module on the basis of the first optical power, wherein the calibration mode comprises:
