QSFP28 Cages & Connectors
2X2 QSFP28 Cage

2X2 QSFP28 Cage

Shop LINK-PP 2×2 QSFP28 cages — stacked 2×2 host receptacles with EMI spring fingers, optional heat sinks, and light-pipe variants for QSFP28 panel rows. This leaf covers press-fit and solder assemblies for dual-height panel cutouts on NIC and switch faceplates. These MSA host cages accept QSFP28 pluggable modules in the classic QSFP envelope—not QSFP-DD / OSFP transceiver hubs, and not pluggable module SKUs. Compare sibling 2X1 QSFP28 Cage or 2X3 QSFP28 Cage, return to the parent QSFP28 Cages & Connectors hub, or browse Fiber Optic Cages & Connectors. Match termination, EMI style, and light-pipe options on each product page before ordering.

Frequently asked questions

01.What is a 2×2 QSFP28 cage on this page?
This leaf lists LINK-PP 2×2 QSFP28 host cages and cage/connector assemblies—metal receptacles that accept QSFP28 pluggable modules at the faceplate. Compare sibling 2X1 QSFP28 Cage or return to the parent QSFP28 Cages & Connectors hub.
02.How does a 2×2 QSFP28 cage differ from single-row 1×N cages?
A 2×2 cage stacks ports in a dual-height column/row for higher faceplate density. Single-row 1×N cages (for example 1X1 QSFP28 Cage or 1X4 QSFP28 Cage) keep one height across the panel width. Choose based on bezel height and port count.
03.How does a QSFP28 cage differ from QSFP, QSFP+, or QSFP-DD cages?
QSFP28 host cages use the classic QSFP MSA faceplate envelope sized for QSFP28 modules. QSFP and QSFP+ family hubs cover earlier QSFP-envelope cages; QSFP-DD and OSFP use different form-factor cages and panel cutouts. Use this QSFP28 leaf (and the parent QSFP28 Cages & Connectors hub) for QSFP28 host hardware; see QSFP Cages & Connectors or QSFP+ Cages when you need those family hubs—not transceiver rate Shop pages.
04.Is a QSFP28 cage the same as a QSFP28 transceiver?
No. A QSFP28 cage is the metal host receptacle (often with connector) soldered or press-fit onto the PCB; the pluggable transceiver or DAC/AOC inserts into that cage. This category sells cages and connectors for board design—not the pluggable modules themselves.
05.Press-fit vs solder, EMI spring fingers, heat sink, and light pipes—what should I check?
Press-fit pins speed board assembly without reflow on the cage; solder tails suit standard SMT/TH processes. EMI spring fingers improve chassis grounding at the faceplate; heat sinks help thermal paths on high-power QSFP28 hosts; light pipes route link/activity LEDs to the bezel. For other port maps open 2X1 QSFP28 Cage or 2X3 QSFP28 Cage, or return to Fiber Optic Cages & Connectors.
