Frequently asked questions

01.What is a 2×4 SFP cage on this page?
This leaf lists LINK-PP 2×4 SFP host cages and cage/connector assemblies—stacked dual-row metal receptacles that accept SFP pluggable modules at the faceplate. Compare sibling 2X2 SFP Cage or return to the parent SFP Cages & Connectors hub.
02.How does a 2×4 SFP cage differ from single-row 1×N cages?
A 2×4 cage stacks two rows of 4 SFP port(s) for dual-height panel density. Single-row 1×N cages (for example 1X1 SFP Cage or 1X4 SFP Cage) stay at one row height. Match stack height to your bezel and PCB keep-out.
03.Is an SFP cage the same as an SFP transceiver?
No. An SFP 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.
04.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 hosts; light pipes route link/activity LEDs to the bezel. Product titles call out the options included—match them to your PCB land pattern and panel cutout.
05.Where do I find other SFP port maps or related cage families?
For other SFP port counts open sibling leaves such as 2X2 SFP Cage and 2X6 SFP Cage, browse the parent SFP Cages & Connectors hub, or return to Fiber Optic Cages & Connectors for SFP+, SFP28, QSFP, and related host form factors.
