QSFP+ Cage for High-Speed I/O — Press-Fit, Right-Angle, Shielded
The TE Connectivity 1888617-1 is a QSFP+ cage from the EVERCLEAR series, designed to house a QSFP+ module at the board edge. The right-angle orientation places the cage parallel to the PCB, directing the cable exit along the board plane for space-constrained enclosures. EMI shielding is integrated into the cage structure, containing radiated emissions from the 4-lane 25 Gbps per lane signalling typical of QSFP+ applications.
Where This Cage Fits in the Build
This cage mates with a QSFP+ pluggable module (not included) and provides mechanical retention, thermal management, and EMI containment. Press-fit pins connect signal pairs, power, and management lines to the host PCB.
Press-Fit Termination — What It Means for Assembly
No solder paste, no reflow profile, no wave solder — the joint is purely mechanical. This gives two practical advantages: the board can be assembled without exposing the cage to soldering temperatures, and a press-fit joint is field-reworkable with a proper extraction tool. The trade-off is that the PCB hole diameter and plating thickness must match the pin design; the board fabricator needs the TE recommended footprint drawing to set the finished hole size.
No end-of-life notification or last-time-buy window has been issued. The base product number is 1888617, and the -1 suffix denotes this tray-packaged, press-fit, right-angle QSFP+ cage with EMI shielding.
