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

Abstract

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 power, wherein the calibration mode comprises the step of calibrating the coherent optical module by adopting a first curve relationship under the condition that the optical power of the receiving end of the coherent optical module is in a first range; and under the condition that the optical power of the receiving end of the coherent optical module is in a second range, calibrating the coherent optical module by adopting the second curve relationship.

Description

technical field [0001] Embodiments of the present invention relate to the field of optical fiber technology, and in particular to a calibration method, device, equipment and computer-readable storage medium for a coherent optical module. Background technique [0002] For traditional coherent optical modules, the total optical power at the receiving end is generally reported by the receiving end photodiode (Photo Diode, PD) for calibration. For miniaturized modules, an external Tap Photo Detector (TAP-PD) cannot be accommodated. , may use the PD integrated in the receiver of the module for reporting and calibration. For module receiving receivers, some manufacturers may not integrate internal PDs. At this time, optical power calibration cannot rely on PDs. How to ensure the linearity of the reporting curve obtained in the entire optical power range of the receiving end without depending on the PD, and improve the reporting accuracy in the entire optical power range. For thi...
