1X4 QSFP Cage

1X4 QSFP Cage

Shop LINK-PP 1×4 QSFP cages — four-port single-row ganged host receptacles with EMI spring fingers, optional heat sinks, and light-pipe variants for dense QSFP panel rows. This leaf covers press-fit and solder assemblies for single-height panel cutouts on NIC and switch faceplates. These MSA host cages share the classic QSFP envelope (QSFP / QSFP+ / QSFP28)—not QSFP-DD / OSFP transceiver hubs, and not pluggable module SKUs. Compare sibling 1X2 QSFP Cage or 1X6 QSFP Cage, return to the parent QSFP Cages & Connectors hub, or browse Fiber Optic Cages & Connectors. Match termination, EMI style, and light-pipe options on each product page before ordering.

Frequently asked questions

01.What is a 1×4 QSFP cage on this page?
This leaf lists LINK-PP 1×4 QSFP host cages and cage/connector assemblies—single-row metal receptacles that accept QSFP-family pluggable modules at the faceplate. Compare sibling 1X2 QSFP Cage or return to the parent QSFP Cages & Connectors hub.
02.How does a 1×4 QSFP cage differ from stacked 2×N cages?
A 1×4 cage places 4 QSFP port(s) in a single-height row. Stacked 2×N cages (for example 2X1 QSFP Cage or 2X2 QSFP Cage) double vertical density in the same panel width. Choose based on faceplate height and port count.
03.How does a QSFP cage differ from QSFP+, QSFP28, or QSFP-DD cages?
Classic QSFP host cages share the QSFP MSA faceplate envelope used by QSFP / QSFP+ / QSFP28 modules. QSFP-DD and OSFP use different form-factor cages and panel cutouts. Use this QSFP leaf (and the parent QSFP Cages & Connectors hub) for classic QSFP host hardware; see QSFP+ Cages or QSFP28 Cages when you need those family hubs—not transceiver rate Shop pages.
04.Is a QSFP cage the same as a QSFP transceiver?
No. A QSFP 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 QSFP hosts; light pipes route link/activity LEDs to the bezel. For other port maps open 1X2 QSFP Cage or 1X6 QSFP Cage, or return to Fiber Optic Cages & Connectors.
