Fiber Optic Cages & Connectors

Fiber Optic Cages & Connectors

Shop LINK-PP fiber optic cages and connectors for host boards that accept pluggable modules—from SFP through QSFP28, QSFP-DD, and OSFP. This manufacturer hub focuses on press-fit and solder cages, EMI spring fingers, light-pipe options, and MSA footprints for switch, NIC, and server designs—not transceiver rate catalogs. Drill into SFP Cages, SFP+ Cages, or QSFP28 Cages by form factor family. Match port map (1×N / 2×N), termination style, EMI gasket, and heat-sink option on each product page before ordering.

Frequently asked questions

01.What does this fiber optic cages hub include?
This page lists LINK-PP host cages and cage-with-connector assemblies for pluggable module ports—SFP, SFP+, SFP28, QSFP, QSFP28, QSFP-DD, OSFP, and related footprints. It is a mechanical/EMI host-port catalog, not a transceiver rate store. Start with family hubs such as SFP Cages & Connectors when you already know the form factor.
02.Press-fit vs solder cage—how do I choose?
Press-fit pins speed panel assembly and often improve grounding consistency on high-volume boards; solder (through-hole) cages suit rework-friendly or lower-volume builds. Always match the cage termination style to your PCB stack-up and assembly process, and confirm MSA cage dimensions for the target module family.
03.Why do cages list EMI spring fingers and light pipes?
EMI spring fingers / gaskets help contain emissions at the faceplate and improve contact to the chassis. Light pipes (or inner LightPipe options) route port LED status to the bezel. Pick the EMI and light-pipe configuration that matches your panel cutout and LED placement—details are on each product page.
04.Are these Compatible replacements for TE, Molex, or other cage PNs?
Many SKUs map common TE, Molex, and other OEM cage part numbers to LINK-PP equivalents (for example LP11BCS2000, LP11ACS2000, LP21A602001). Open the Compatible PDP for your OEM PN, verify port map, pin length, EMI style, and light-pipe option, then order the LINK-PP P/N.
05.Do these cages include the host connector?
Some listings are cage-only; others are cage & connector (integrated) assemblies. The product title and datasheet state whether the electrical connector is included. Confirm pin count, solder/press-fit of the connector, and MSA alignment before you freeze the BOM.
