Abstract

An electromagnetically shielded optical transceiver module is disclosed. The transceiver includes a housing formed by top (105) and bottom (115) housing portions that are joined to define a cavity. A printed circuit board (110) is positioned within the cavity and includes an edge connector (112) extending from one housing end. The printed circuit board (110) includes two holes defined near the edge connector and lined with electrically conductive material to form conductive vias (120). Conductive plates (130) located on both the top and bottom housing portions electrically connect with the conductive holes to electrically interconnect the top (105) and bottom (115) housing portions. A chassis ground from one or both of the housing portions extends through the plates (130) and holes to create a 'chassis ground fence'.
