In accordance with the teachings of the present invention, wavelength selective switch (WSS) design configurations for mesh light-trails are provided. In a particular embodiment, a node included in an optical network comprises a first light access unit operable to add or drop local traffic and a first WSS assembly communicatively coupled to the first light access unit and comprising at least four WSSs, at least two input ports, and at least four output ports, the four WSSs configured to direct any input traffic in any wavelength received at one of the input ports to the first light access unit and/or to any of the output ports.
