Abstract

System and method for optimizing optical power management along one or more optical channels of an optical communication network (OCN), the OCN comprising a plurality of optical channels. The method comprises accessing a digital twin (DT) of the OCN, receiving a desired optimization instruction to optimize the one or more optical channels in view of at least one operational parameter, executing an optical power optimization module on the DT by simulating application of at least one network configuration of the at least one optical channel, each network configuration having a corresponding predicted optimized level indicative of expected performances of the at least one optical channel of the OCN for the corresponding network configuration. In response to the predicted optimization level of a given network configuration satisfying a criterion, the network configuration is identified as a target network configuration and applied on the OCN.
