SFP Cage for Board-Edge Transceiver Mounting
The TE Connectivity 2227303-2 is an SFP cage connector designed to house standard SFP transceiver modules at the board edge. It mounts through-hole with a right-angle orientation, placing the cage parallel to the PCB for a low-profile I/O port. The integrated EMI shielding contains radiated emissions from the transceiver, which is essential for keeping the port clean in switch, router, and media-converter designs where the cage sits at the panel opening.
The right-angle through-hole footprint puts the solder tails on the board edge, with the cage body extending beyond the PCB edge to align with the panel cutout. The through-hole leads handle the mechanical retention of the cage and the ground return path. The EMI shield is integral to the cage — no separate gasket or clip is needed at the panel face, which simplifies the chassis cutout design.
