obtaining, by a controller, a plurality of optical channel power values for each of a plurality of channels along a C-Band spectrum, wherein the plurality of channels are used for transmitting optical signals on an optical link by a plurality of optical transmitters and wherein the plurality of optical channel power values are obtained by monitoring power at an input or an output of an amplifier on the optical link;

determining, by the controller, an optical power distribution among the plurality of channels based on a maximum optical power and a minimum optical power from among the plurality of optical channel power values of the plurality of channels, wherein the optical power distribution includes a respective power deviation value for each of the plurality of channels along the C-Band spectrum;

generating, by the controller, a plurality of adjusted channel power values by equalizing the plurality of optical channel power values based on the optical power distribution to reduce a signal to noise ratio (SNR) variation and by scaling the plurality of optical channel power values based on a maximum allowable optical power for each of the plurality of optical transmitters; and

configuring, by the controller, the plurality of optical transmitters for transmitting the optical signals, via the plurality of channels, on the optical link based on the plurality of adjusted channel power values.
