A node for an optical network includes a demultiplexer operable to
separate an ingress wavelength division multiplexed (WDM) signal into a
plurality of ingress channels. An ingress amplifier array is coupled to
the demultiplexer and includes a plurality of channel amplifiers. The
channel amplifiers are each operable to independently amplify one of the
ingress channels while maintaining a channel power variation between the
channels within an operational limit of the network.
