METHOD, DEVICE AND SYSTEM FOR OPTICAL POWER DEBUGGING

摘要

Provided is a method for optical power debugging. The method comprises: calculating the degradation coefficient corresponding to each service according to the property thereof; calculating the nominal signal to noise ratio output among nodes according to the nominal signal to noise ratio input and nominal power input among nodes; calculating the nominal degradation degree of the OSNR among nodes according to the nominal signal to noise ratio input and output among nodes; calculating the target degradation degree of each service among nodes according to the degradation coefficient corresponding to each service and the nominal degradation degree of the OSNR among nodes; calculating the target optical power adjustment value of each service on the sending end node according to the target degradation degree of each service among nodes; and sending the target optical power adjustment value of each service on the sending end node to an optical power adjustment unit on the sending end node so as to adjust the optical power of each service. Also provided are a device and system for optical power debugging. The transmission signal quality of the receiving end can be averaged by using the present invention.
