Electromagnetic radiation shielding on a pci express card

A peripheral component interconnect express (PCIe) card comprising:

• a bezel defining an opening;
• two or more adjacent transceiver modules positioned in the opening;
• a printed circuit board (PCB) mechanically coupled to the bezel and to the transceiver modules;
• and
• an electromagnetic radiation (EMR) shield configured to reduce EMR that escapes through the opening from a host device into which the PCIe card is received, the EMR shield including a structure defining an enclosure configured to at least partially enclose the transceiver modules, the EMR shield further including a plurality of fingers extending from the structure and configured to contact the bezel at a plurality of contact areas substantially surrounding the opening.
