It terminates via press-fit pins into a through-hole, right-angle footprint — no solder required, which keeps rework and thermal stress off the board. The cage carries EMI shielding and a light pipe for link status indication, common in high-density switch and router line cards where per-port visual feedback and signal integrity matter.
This is a ZQSFP+ cage, not a standard QSFP+ — the Z prefix indicates it supports higher data rates (typically 28 Gbps per lane and above) while maintaining backward compatibility with QSFP+ modules. The ganged 1 x 6 layout means six ports in a single body, saving PCB real estate compared to individual cages. The integrated heat sink pulls heat from the module directly, essential for sustained high-speed operation in a constrained airflow chassis. Press-fit termination avoids solder joints, making it a good fit for backplanes or boards where rework access is limited.
