Frequently asked questions

01.What is a 2×4 SFP28 cage on this page?
This leaf lists LINK-PP 2×4 SFP28 host cages and cage/connector assemblies—stacked dual-row metal receptacles that accept SFP28 / zSFP+ pluggable modules at the faceplate. Compare sibling 2X2 SFP28 Cage or return to the parent SFP28 Cages & Connectors hub.
02.How does a 2×4 SFP28 cage differ from single-row 1×N cages?
A 2×4 cage stacks two rows of 4 SFP28 port(s) for dual-height panel density. Single-row 1×N cages (for example 1X1 SFP28 Cage or 1X4 SFP28 Cage) stay at one row height. Match stack height to your bezel and PCB keep-out.
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 2X2 SFP28 Cage or 2X6 SFP28 Cage, or return to Fiber Optic Cages & Connectors.
