SFP28 Cages & Connectors
2X12 SFP28 Cage

2X12 SFP28 Cage

Shop LINK-PP 2×12 SFP28 cages — stacked dual-height twelve-column host receptacles with EMI spring fingers, optional heat sinks, and light-pipe variants for SFP28 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 SFP28 / zSFP+ pluggable modules in the SFP envelope—not SFP+ / classic SFP / SFP56 cage hubs, and not pluggable module SKUs. Compare sibling 1X3 SFP28 Cage or 2X4 SFP28 Cage, return to the parent SFP28 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 2×12 SFP28 cage on this page?
This leaf lists LINK-PP 2×12 SFP28 host cages and cage/connector assemblies—metal receptacles that accept SFP28 / zSFP+ pluggable modules at the faceplate. Compare sibling 1X3 SFP28 Cage or return to the parent SFP28 Cages & Connectors hub.
02.How does a 2×12 SFP28 cage differ from single-row 1×N cages?
A 2×12 cage stacks ports in a dual-height column/row for higher faceplate density. Single-row 1×N cages (for example 1X1 SFP28 Cage) keep one height across the panel width. Choose based on bezel height and port count.
03.How does an SFP28 cage differ from an SFP+ or SFP cage?
All three share the same MSA pluggable faceplate envelope, but SFP28 / zSFP+ host cages are specified for higher-rate thermal paths and EMI spring-finger options on SFP28-class hosts. Use this SFP28 leaf (and the parent SFP28 Cages & Connectors hub) for SFP28 host hardware; see SFP+ Cages & Connectors or SFP Cages & Connectors when you need SFP+ or classic SFP cages—not transceiver rate Shop pages. For next-gen SFP56 / SFP112 host cages see SFP56 / SFP112 Cages & Connectors.
04.Is a SFP28 cage the same as a SFP28 transceiver?
No. A SFP28 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 SFP28 hosts; light pipes route link/activity LEDs to the bezel. For other port maps open 1X3 SFP28 Cage or 2X4 SFP28 Cage, or return to Fiber Optic Cages & Connectors.
