The TE Connectivity 2170519-1 is a single-port QSFP cage designed for high-speed data center and networking equipment. It uses press-fit termination into a through-hole, right-angle PCB footprint, which means the cage is pressed into plated holes — no solder required — giving a gas-tight connection that handles the mechanical retention of the module and the ground return path. The integrated EMI shielding contains radiated emissions from the transceiver, a requirement for systems running 10 GbE and above per port. This cage mates with standard QSFP modules (QSFP, QSFP+, QSFP28) and sits in the 2170519 base product family.
Press-Fit Installation — What It Means on the Line
Press-fit termination avoids the thermal stress of wave soldering on the cage and the nearby PCB vias. The compliant pin geometry deforms elastically into the plated through-hole, creating a reliable interconnect without a solder joint. The EMI shield fingers contact the panel or chassis cutout when the cage is installed in a metal bezel.
The tray packaging is standard for these cages; each tray holds a fixed quantity that matches the pick-and-place or hand-placement process on the assembly line.
