Abstract
An optical device for conditioning a multi-channel optical signal is provided, comprising a channel separation and assembly unit and a signal processor. The signal processor comprises an optical attenuator for adjusting the power level of the signals, an optical detector for detecting the power level associated with each of the multiple channels, a reflective medium disposed between the optical attenuator and detector, and a microprocessor-based controller in electrical communication with the attenuator and detector for dynamically controlling the power distribution of the output signal.
