What This QSFP+ Receptacle with Cage Is
The TE Connectivity 2214574-6 is a QSFP+ receptacle with cage, configured as a ganged 1x4 stack — four ports in a single housing, each port carrying 38 positions for a total of 152 (38 x 4) circuits. This is the I/O connector for high-speed data center and telecom gear: the cage integrates the EMI shield and a light pipe for port status indication, and the press-fit termination eliminates soldering for a cleaner backplane assembly. The through-hole, right-angle mounting orients the cage parallel to the board edge, matching the standard card-edge I/O layout for switch, router, and server line cards.
Press-fit termination means the compliant pins are pressed into plated through-holes — no solder joint, no reflow profile to manage. Board layout engineers need to account for the keep-out zone around the cage for airflow and the light pipe clearance on the front panel.
EMI Shield and Light Pipe
The integrated EMI shield is part of the cage — it grounds to the chassis through the press-fit pins and the cage's own grounding tabs, containing the radiated emissions.
