SFP28 Cages & Connectors
1X3 SFP28 Cage

1X3 SFP28 Cage

Shop LINK-PP 1×3 SFP28 cages — three-port single-row 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 single-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 2X12 SFP28 Cage or 1X4 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 1×3 SFP28 cage on this page?
This leaf lists LINK-PP 1×3 SFP28 host cages and cage/connector assemblies—metal receptacles that accept SFP28 / zSFP+ pluggable modules at the faceplate. Compare sibling 2X12 SFP28 Cage or return to the parent SFP28 Cages & Connectors hub.
02.How does a 1×3 SFP28 cage differ from stacked 2×N cages?
A 1×3 cage places SFP28 port(s) in a single-height row. Stacked 2×N cages (for example 2X4 SFP28 Cage or 2X8 SFP28 Cage) double vertical density in the same panel width. Choose based on faceplate 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 2X12 SFP28 Cage or 1X4 SFP28 Cage, or return to Fiber Optic Cages & Connectors.
