Abstract
A method of loading a fiber optic transport system includes detecting optical power in a frequency sub-band of optical spectrum, wherein the frequency sub-band includes data-bearing channels and at least one control channel; measuring optical power in the frequency sub-band; and adjusting optical power of the at least one control channel based on the measured optical power, wherein the optical power is adjusted through one of changing a current of control channel lasers and controlling a set of fast optical attenuators.
