The TE Connectivity 2227023-1 is a single-port SFP cage — the metal housing that receives a pluggable SFP transceiver module and anchors it to the PCB. It belongs to the 2227023 base series and carries the EMI shielding needed to keep radiated emissions inside the chassis. The cage is the mechanical and thermal interface for the module; the actual signal contacts live on a separate connector pressed into the back of the cage. Press-fit termination means the cage pins are pressed into plated through-holes on the board — no solder required. This keeps assembly lead-free by default and makes rework straightforward: desolder the separate signal connector if needed, then press the cage out from the back side.
Board Layout and Compatibility
The cage accepts standard SFP and SFP+ modules — the mechanical envelope follows the SFP Multi-Source Agreement (MSA), so any MSA-compliant transceiver fits. The press-fit pins land on a through-hole footprint; the exact pad pattern and keep-out zone are defined in the TE product drawing. The right-angle mount places the cage body on the board edge, with the module insertion slot facing outward. The EMI shield contacts the chassis ground through the cage's spring fingers — ensure the board ground plane connects to the press-fit pin vias to complete the shield.
