QSFP28 Cages & Connectors

QSFP28 Cages & Connectors

Shop LINK-PP QSFP28 cages and connectors for high-density host ports that accept QSFP28 pluggable modules. This family hub lists 1×N and 2×N cages with EMI spring fingers, heat-sink and light-pipe options, plus cage/connector assemblies for switch and NIC faceplates—host receptacle hardware, not transceiver rate catalogs. Compare sibling hubs such as SFP+ Cages, OSFP Cages, or the parent Fiber Optic Cages hub. Confirm port map, press-fit vs solder, EMI, and heat-sink height on each product page before ordering.

Frequently asked questions

01.What QSFP28 cage configurations are in this category?
This store lists LINK-PP QSFP28 host cages and cage/connector assemblies in 1×N and 2×N maps (for example 1×1, 1×2, 1×4, 2×1, 2×2), with EMI spring fingers, heat-sink, and light-pipe options where offered. Return to the parent Fiber Optic Cages hub to browse all form factors.
02.Is a QSFP28 cage the same as a QSFP28 transceiver?
No. A QSFP28 cage is the metal host receptacle soldered or press-fit onto the PCB; the pluggable QSFP28 module inserts into that cage. This category sells cages and connectors for board design—not the pluggable optics or DAC/AOC modules themselves.
03.When do I need a heat sink or light pipe on a QSFP28 cage?
Heat-sink options help dissipate module heat at high port density; light pipes bring port LED status to the bezel. Choose based on your thermal budget and panel LED placement—product titles call out Heat Sink and Light Pipe where included.
04.Are Molex / Amphenol QSFP28 cage PNs available as LINK-PP Compatible parts?
Yes—many listings map Molex and Amphenol QSFP28 cage PNs to LINK-PP equivalents such as LP21FC01603, LP11FC01050, and LP22FC01003S. Open the Compatible product page, verify port map and EMI/heat-sink options, then order the LINK-PP P/N shown.
05.Where do I find OSFP or SFP+ cages instead?
For other host form factors, open OSFP Cages, SFP+ Cages, or the parent Fiber Optic Cages & Connectors hub.
