Abstract
Disclosed are a calibration method and apparatus for a coherent light module, and a computer-readable storage medium. The method comprises: obtaining a first and second curve relationship respectively representing a relationship between a power-gain monitoring voltage and optical power of a receiver of the coherent optical module and a relationship between a target setting voltage and the optical power of the receiver in the optical power range of the receiver; determining first optical power based on the first and second curve relationship, which is used for dividing the optical power range of the receiver into two ranges; and determining a calibration mode of the coherent light module based on the first optical power, which comprises: calibrating the coherent light module by using the first curve relationship or the second curve relationship when the optical power of the receiver is in a first range or in a second range.
