Abstract:
1. A wavelength selective switch module comprising: an enclosure including a base, a sidewall, and a lid; an optical input port for receiving an input optical signal, the input optical signal including a plurality of wavelength channels; an optical output port for transmitting an output optical signal, the output optical signal including at least one wavelength channel in the plurality of wavelength channels; an optical switching engine attached to the base within the enclosure, the optical switching engine including an array of switching elements for directing the at least one wavelength channel from the optical input port to the optical output port; and an optical bench attached to the base within the enclosure, the optical bench supporting a plurality of optical components for optically coupling the optical input port to the array of switching elements and the optical output port, the plurality of optical components including a dispersive element for dispersing the input optical signal into the plurality of wavelength channels; wherein the optical bench is attached to the base with a plurality of mounts, the plurality of mounts including at least one movable mount supporting movement of the optical bench in a plane parallel to the optical bench and at least one fixed mount maintaining optical alignment between the dispersive element and the array of switching elements.
