A dynamic power equalization module ( ) for an optical network is provided. It includes a module input ( ) for receiving an optical transmission ( ) containing a combination of different channels (C -C ). Each channel (C -C ) has a different characteristic wavelength (&lgr; -&lgr; ) and different varying power. A power equalization device that is polarization insensitive is connected between the module input ( ) and a module output ( ). The power equalization device is driven by RF acoustic signals ( ). A feedback loop ( ) receives at least a portion of output from the module output ( ) and generates, based upon a comparison of relative powers of the different channels (C -C ), the RF acoustic signals ( ) which drive the power equalization device. The power equalization device is driven such that it dynamically controls transmission of the different channels (C -C ) to substantially equalize power differentials therebetween. The power equalization device includes a parallel array of acousto-optic modulators (AO -AO ).
