The TE Connectivity 2227316-1 is an SFP cage connector — the metal housing that shields and aligns a pluggable SFP or SFP+ transceiver module to the PCB. It uses press-fit termination, so the tails are compliant pins that cold-weld into plated through-holes without a solder wave, which keeps the assembly lead-free and cuts a reflow step. The right-angle orientation means the module inserts parallel to the board, typical for line-card edge or mid-plane layouts where the cage faces the panel cutout. The EMI shielding is integral to the cage design, not an add-on gasket — it contains radiated emissions from the module cavity to pass FCC/EN Class B at the system level.
Press-Fit Assembly and Board Layout
Press-fit termination means the 2227316-1 is designed for a solderless backplane or daughtercard assembly line. The compliant pin geometry — fish-eye or needle-eye style — compresses as it enters the hole and holds retention by interference fit. This avoids thermal shock to the housing and lets you rework a mis-seated cage by pressing it out. The board footprint must match the pin pattern and the panel cutout dimensions for the cage face — the datasheet gives the keep-out zone for the cage body and the light-pipe if used. Bulk packaging means the parts ship loose in a bag or tube, not on a reel; fine for hand-placement or low-volume assembly, but if you run a pick-and-place line you will want to confirm the tray or tube format fits your feeder.
Compatibility and Common Questions
The 2227316-1 is an SFP cage, designed to accept standard SFP and SFP+ transceiver modules that meet the SFP MSA mechanical envelope. The cage provides the EMI spring fingers and the grounding clip that mates with the module's shell. It does not include a dust cover as a fitted accessory — the cage opening is a standard SFP port, so any SFP dust plug with the same outer dimensions will fit. The cutout size for the panel opening is specified in the TE product drawing; the cage face includes the alignment pins and the latch slots for the module bail.
