QSFP28 Connectors

Shop LINK-PP QSFP28 connectors — board-mount QSFP28 / QSFP112 receptacle connectors for host PCB layouts—38- and 76-position solder and SMT footprints that mate with matching QSFP28 cages. This leaf covers host-side connector hardware for NIC and switch designs—not QSFP / QSFP+ / QSFP-DD / OSFP connector leaves, and not pluggable module SKUs. Compare sibling QSFP+ Connectors or QSFP-DD Connectors, return to the matching QSFP28 Cages & Connectors cage hub, or browse Fiber Optic Cages & Connectors. Match pin count, orientation, and termination on each product page before ordering.

Frequently asked questions

01.What are QSFP28 connectors on this page?
This leaf lists LINK-PP QSFP28 board-mount receptacle connectors—host PCB footprints that mate with QSFP28 cages at the faceplate. Compare sibling QSFP+ Connectors or return to the matching QSFP28 Cages & Connectors cage hub.
02.How do QSFP28 connectors differ from QSFP28 cages?
A QSFP28 connector is the electrical receptacle soldered or SMT-mounted on the PCB; a QSFP28 cage is the metal EMI shell that guides the pluggable module into that connector. Use this connector leaf for PCB footprints; open QSFP28 Cages & Connectors when you need host cages and cage/connector assemblies.
03.How do QSFP28 connectors differ from QSFP+ or QSFP-DD connectors?
QSFP28 connectors target QSFP28 / QSFP112 host footprints (often 38- or 76-position), while QSFP+ leaves cover earlier QSFP+ receptacles and QSFP-DD leaves cover denser double-density hosts. Stay on this QSFP28 leaf (and QSFP28 Cages & Connectors) for QSFP28 hardware; see QSFP+ Cages & Connectors or QSFP-DD Cages & Connectors for those cage families—not transceiver rate Shop pages.
04.Is a QSFP28 connector the same as a QSFP28 transceiver?
No. A QSFP28 connector is the board-mount electrical receptacle; the pluggable transceiver or DAC/AOC inserts through a mating cage into that connector. This category sells host connectors for board design—not the pluggable modules themselves.
05.Pin count, orientation, SMT vs solder—what should I check?
Confirm position count, right-angle vs vertical orientation, SMT vs through-hole solder tails, and plating against your PCB footprint and cage stack-up. For other connector families open QSFP+ Connectors or QSFP-DD Connectors, or return to Fiber Optic Cages & Connectors.
