What This QSFP28 Cage Does in the Assembly
The TE Connectivity 2227250-1 is a QSFP28 cage in a ganged 1 x 4 configuration — four QSFP28 ports side-by-side in a single shielded housing. It accepts standard QSFP28 optical transceivers or direct-attach copper cable assemblies, providing the mechanical retention, thermal management interface, and EMI containment those modules require. The press-fit termination eliminates soldering, which suits backplane or mid-plane assemblies where rework access is limited and the board goes through a solderless press-fit process.
Mounting and Termination — Board-Edge Fit
The through-hole press-fit tails engage plated through-holes without solder, which means the cage can be pressed into the board alongside other press-fit connectors in a single backplane assembly step. Tray packaging (the listed package) is typical for press-fit parts that feed into automated placement or manual press tooling; the trays keep the cages oriented for pick-and-place or hand loading.
Active lifecycle status — TE Connectivity continues to manufacture the 2227250-1, so it is available for both new designs and production replenishment.
