What the TE 2345214-1 SFP-DD Cage Is
The TE 2345214-1 is a ganged 1x6 SFP-DD (Double Density) cage — a press-fit, right-angle through-hole interconnect component designed for high-port-count I/O on switch, router, and server backplanes. The SFP-DD form factor doubles the electrical interface density of standard SFP cages by adding a second row of contacts, supporting aggregate data rates up to 400 GbE per port when paired with the appropriate module. The EMI shielded construction contains radiated emissions within the chassis, a requirement for passing FCC and EMC compliance in data-center equipment. The press-fit termination eliminates the thermal stress of wave soldering on the backplane and simplifies field rework of individual cages.
Mounting and Termination Detail
The through-hole mounting provides mechanical retention against the insertion and extraction forces of SFP-DD modules over repeated mating cycles.
Comparison with the 2227302-3
The 2227302-3 is a ganged 1x6 SFP-DD cage with the same press-fit, right-angle through-hole mounting and EMI shielding. The primary difference is packaging: the 2345214-1 ships in a Tray, while the 2227302-3 ships in a Box. For high-volume pick-and-place or panel assembly, the packaging format affects feeder compatibility and kitting workflow. Both parts are Active and functionally interchangeable for the same PCB footprint and module interface.
