Abstract
Systems and methods for stabilizing power levels from excessive oscillations in an optical line system of a communications network are provided. A method, according to one implementation, includes the step of detecting a perturbation of an optical power level in an optical line system having a plurality of cascaded optical power controllers. The method also includes the step of determining an estimated location to which a power controller of the plurality of cascaded optical power controllers is positioned downstream of the perturbation with respect to other power controllers of the plurality of cascaded optical power controllers. Based on the estimated location to which the power controller is positioned downstream of the perturbation, the method also includes the step of providing feedback in a control loop to reduce the effects of the perturbation.
