Frequently asked questions

01.What is a 1×4 SFP28 cage on this page?
This leaf lists LINK-PP 1×4 SFP28 host cages and cage/connector assemblies—single-row metal receptacles that accept SFP28 / zSFP+ pluggable modules at the faceplate. Compare sibling 1X2 SFP28 Cage or return to the parent SFP28 Cages & Connectors hub.
02.How does a 1×4 SFP28 cage differ from stacked 2×N cages?
A 1×4 cage places 4 SFP28 port(s) in a single-height row. Stacked 2×N cages (for example 2X1 SFP28 Cage or 2X2 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, EMI spring-finger options, and 25G-class host designs. 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.
04.Is an SFP28 cage the same as an SFP28 transceiver?
No. An 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 1X2 SFP28 Cage or 1X6 SFP28 Cage, or return to Fiber Optic Cages & Connectors.
