Techniques are presented herein to set power levels for multiple Raman pump wavelengths in a distributed Raman amplification configuration. A first receive power measurement is obtained at a second node with a controlled optical source at a first node turned on and with a plurality of Raman pump lasers at different wavelengths at the second node turned off. A second receive power measurement is obtained at the second node with the controlled optical source at the first node turned on and the plurality of Raman pump lasers turned on to respective reference power levels to inject optical Raman pump power at a corresponding plurality of wavelengths into the optical fiber span. Based on a target Raman gain and a target Raman gain tilt, respective ratios of a total power are obtained, each ratio to be used for a corresponding one of the plurality of Raman pump lasers.

Disclosed herein are methods and systems configuring a raman amplifier. One exemplary system may be provided with an optical amplifier deployed in an optical network, the optical amplifier having a plurality of raman pumps configured to obtain a desired gain profile. An actual gain profile and a raman pump configuration of each of the plurality of raman pumps may be processed by a network administration device using a first machine learning model to produce a combined optical transmission segment attribute representing attributes of an optical segment of the optical network. The combined optical transmission segment attribute and the desired gain profile may be processed with a second machine learning model to produce corrected raman pump configurations for each of the plurality of raman pumps of the raman amplifier. The corrected raman pump configurations may be used to configure each of the plurality of raman pumps of the raman amplifier.

Disclosed herein are methods and systems for optimizing an optical signal in an optical network having a hub node configured to receive an optical signal comprising a plurality of subcarrier groups each having a signal quality and a transmission output power, including a method that may comprise: determining, a first subcarrier group of the plurality of subcarrier groups with a lowest signal quality lower than a required signal quality margin; determining, a second subcarrier group of the plurality of subcarrier groups that has a highest transmission output power margin, Determining, that the transmission output power margin of the second subcarrier group is above a level needed to increase the lowest signal quality by a required signal quality increase; and sending signals to a first leaf node and a second leaf node causing the first leaf node to swap transmission positions of the first subcarrier group and the second subcarrier group.
