Abstract
A transceiver module that utilizes an electromagnetic interference (EMI) containment structure for dealing with electromagnetic interference generated within the transceiver module. In one example embodiment, a transceiver module includes a housing, a printed circuit board disposed within the housing, and an EMI shield disposed about the printed circuit board. In this example embodiment, the printed circuit board includes electronic circuitry and a plurality of differential signal lines. Further, the EMI shield includes a body having a slot, a plurality of fingers on at least one edge of the body, and tabs that are operative to connect the body to the printed circuit board. The slot of the EMI shield receives the printed circuit board such that the differential signal lines of the printed circuit board pass through the slot. The fingers of the EMI shield enable the body to maintain a biased contact with the housing.
