Abstract
A node that is colorless, directionless and contentionless includes an add/drop terminal having an add wavelength selective switch (WSS) and a drop WSS. The add and drop WSSs are each configured to selectively direct any subset of the wavelength components received at any of its inputs to a different one of its optical outputs, provided that the wavelength components of optical beams received by any two of the inputs cannot be simultaneously directed to a common one of the outputs. A plurality of transponder ports are each optically coupled to a different output of the drop WSS and a different input of the add WSS.
