Coherent optical module calibration method and device, equipment and computer readable storage medium

The invention discloses a coherent optical module calibration method and device, equipment and a computer readable storage medium. The coherent optical module calibration method comprises the steps ofobtaining a first curve relationship and a second curve relationship, wherein the first curve relationship represents the relationship between the power gain reporting voltage and the receiving end optical power in the receiving end optical power range corresponding to the coherent optical module, and the second curve relationship represents the relationship between the target set voltage and thereceiving end optical power in the receiving end optical power range corresponding to the coherent optical module; determining first optical power based on the first curve relationship and the secondcurve relationship, wherein the first optical power is used for dividing the optical power range of the receiving end into two ranges; determining a calibration mode of the coherent optical module based on the first optical po
