Abstract
An input port of an add/drop node receives a plurality of optical channels. An add/drop port transmits a first drop channel of the plurality of channels when in a first channel mode and a second drop channel of the plurality of optical channels during a second channel mode. When the add/drop node is tuned from the first channel to the second channel, the output port transmits the plurality of channels spectrally located between the first channel and the second channel.
