The TE Connectivity 2-2170808-3 is a QSFP28 cage — a ganged 1 x 2 cage with an integrated heat sink, designed for high-speed data center and networking equipment. It accepts two QSFP28 modules side-by-side, each capable of 28 Gbps per lane for 100 GbE or 100G InfiniBand applications. The press-fit termination eliminates soldering, making it suitable for backplane or mid-board assembly where rework or high-reliability solderless connections are preferred.
Key Features and Mounting
The cage mounts through-hole, right-angle to the PCB, positioning the module ports parallel to the board edge for front-panel access. Integrated EMI shielding and a light pipe are built into the cage — the shielding controls radiated emissions at the panel opening, and the light pipe brings the module status LED to the front bezel without a separate light guide assembly.
