ABSTRACT:
A voltage potential at a selected one or more inputs is controlled in order to produce a gain associated with an optical amplifier. One or more characteristics associated with a feedback loop coupled to the optical amplifier may be stored. A signal may be communicated to identify the occurrence of an error associated with the feedback loop. A selected current value may be provided to an element such that the optical amplifier is restored to a state associated with the optical amplifier prior to the failure. The selected current value is based on one or more of the characteristics associated with the feedback loop.
