Abstract
An example embodiment of the present invention is a non-blocking wavelength switching architecture that enables graceful scaling of a network wavelength switching node from small to large fiber counts using fixed size bidirectional 1×N Wavelength Selective Switches (WSS). The architecture uses an intermediate broadcast and select layer implemented using optical splitters and WSSs to eliminate wavelength blocking.
