ABSTRACT:
Described herein are one or more embodiments of a system and method for managing power in an optical network using a variable optical attenuator (VOA). In one embodiment, the attenuation of the VOA is controlled in a feedback loop in accordance with a plural zone method. In one example, the VOA is a mechanical VOA. In another example, the VOA is a latching VOA.
