Board-Mount I/O Port for 56 Gbps Line Cards
It mounts through-hole, right-angle to the PCB, using press-fit termination — no solder wicking into the signal vias, which matters for the impedance control at 25+ Gbps per lane. The cage includes EMI shielding and a light pipe for port status indication, so this one part covers the thermal management, EMC containment, and visual identification that a bare connector would need separate add-ons for.
The through-hole mounting gives the cage mechanical retention against the insertion and extraction forces of a ZQSFP+ transceiver module. Tray packaging means the part arrives in a rigid carrier, not a tape-and-reel — the pick-and-place nozzle handles the cage body directly.
