ABSTRACT:
A shield element for reducing electromagnetic interference (“EMI”) in an optical transceiver module assembly. The transceiver module assembly includes an optical transceiver received within a cage. The cage mounts to a host board and receives in one end thereof a right angle connector of the host board. A rear end of the optical transceiver includes an edge connector that electrically interfaces with a receptacle of the right angle connector. An EMI shield element is interposed between the rear end of the optical transceiver and the right angle connector. The EMI shield element includes a base that surrounds a portion of the right angle connector. Wall portions upwardly extend from the base around the right angle connector to form an angled shield seating surface that engages with a complementarily angled seating surface on the transceiver rear end, thereby forming an EMI shield when the optical transceiver is received into the cage.
