Abstract
An apparatus for mechanical packaging of a piezo-actuator based add/drop module is disclosed. In one aspect of the invention, the combination of an assembly base and an optical add/drop module base provide the alignments for placing triangular prisms and a hexagonal prism. The assembly base has several sets of cylindrical pins where each set of cylindrical pins extends through the OADM base for positioning of a triangular prism or a hexagonal prism. In another aspect of the invention, a set of cylindrical pins extends through the OADM base for placement of a bimorph actuator.
