Abstract: The present invention relates to an electronic module, such as an opto-electronic transceiver or a copper transceiver, for plugging into a host receptacle. In an effort to eliminate the use of costly and inefficient sheet metal spring fingers for reducing EMI emissions, the present invention proposes to use solid conductive projections extending outwardly from the sides and top of the module housing. However, in highly populated host receptacles, adjacent cages often share a common sheet metal wall, which will deform when a module with a solid projection extending therefrom is inserted, thereby making insertion of an adjacent module very difficult. The present invention eliminates this problem by vertically offsetting projections on the opposite sides of the housing so no two projections are in the same horizontal plane.
