ZQSFP+ Cage — 1x2 Ganged with Integrated Heat Sink
This means the thermal management for both module ports is integrated into the single metal housing — no separate heat sink procurement or assembly step. The cage is EMI shielded, which is essential for containing the high-frequency noise from 25 Gbps and 28 Gbps serial links inside a switch or line card. Termination is press-fit, so there is no soldering required for the cage tails. Press-fit gives a reliable gas-tight connection and makes rework simpler than a soldered cage.
Module Compatibility — ZQSFP+ vs QSFP+ and QSFP28
The 2227103-3 is a ZQSFP+ cage. ZQSFP+ is the enhanced version of the QSFP+ form factor, designed to handle higher data rates while maintaining backward compatibility with standard QSFP+ modules.
