Abstract
A method and apparatus is disclosed for optic signal power control to maintain a desired or optimum optic signal power level. During start-up, a target value from memory may be utilized to control one or more power levels of an optic signal. There may comprise 2 or more different power levels for the optic signal. During operation, target values may continue to be utilized or an open loop or closed loop control system may be utilized. Compensation may occur for both additive noise/distortion and multiplicative noise/distortion. The compensation for one power level may be expanded or extrapolated to compensate for additive noise/distortion and multiplicative noise/distortion that affect other power levels.
