It carries 152 positions arranged as 38 per port, press-fit termination, and a right-angle through-hole mounting orientation that places the cage parallel to the board edge. An integrated board guide steers the module into alignment during insertion, and the EMI shielding is built into the cage, eliminating the need for a separate gasket or clip. This connector is designed for high-speed differential-pair signalling at 25 Gbps per lane and above — the ZQSFP+ interface supports 100G, 200G, and 400G Ethernet links depending on the transceiver module plugged in.
The board guide feature is a molded alignment post that engages the PCB before the press-fit pins enter their holes, preventing pin stubbing during assembly.
Compatibility with QSFP28 and ZQSFP+ Modules
The ZQSFP+ form factor is the physical and electrical evolution of the QSFP+ interface. The 2227670-7 receptacle is mechanically compatible with QSFP28 modules (100G per port) and ZQSFP+ modules (200G/400G per port) that follow the same 38-position pinout per port. The key difference from the earlier QSFP+ is the higher-speed signal integrity — the ZQSFP+ cage and contact geometry are optimised for 25 Gbps NRZ and 56 Gbps PAM-4 signalling. The 2x2 ganged configuration means four ports share one metal shell, which saves board area compared to four individual cages.
