Single-Port 100 Gbit/s Adapter

The Mellanox MCX453A-FCAT is a ConnectX-4 VPI plug-in card that delivers 100 Gbit/s through one QSFP port. It targets data-centre servers and high-performance clusters that need low-latency fabric connectivity. The card occupies a PCI Express 3.0 x8 slot and measures 69 mm by 142 mm.

Check Slot and Cable Compatibility

Verify that your motherboard or riser provides a free PCI Express 3.0 x8 electrical connection and physical clearance for a 142 mm long card. You must also source a compatible QSFP transceiver or direct-attach cable rated for the intended link speed. The adapter requires no auxiliary power connector.

Plug-in Card Build with QSFP Cage

The board weighs 0.4 kg and meets RoHS-6 environmental standards. A standard-height bracket fits typical 2U and taller rack chassis. The single QSFP cage accepts hot-pluggable optics or copper assemblies, allowing media changes without tools or downtime.

Questions about this item

Does the MCX453A-FCAT ship with a QSFP transceiver or cable, or must I purchase one separately?

The adapter provides a single QSFP cage; no transceiver or cable is included, so a compatible QSFP module or direct-attach cable must be bought separately.

The card lists 100 Gbit/s — is that the only speed grade available for this part number?

MCX453A-FCAT is a single 100 Gbit/s FDR VPI adapter; there are no alternate capacity or speed versions under this exact MPN.

When installed in a PCIe 3.0 x8 slot, will the adapter sustain the full 100 Gbit/s rate?

The host interface is PCI Express 3.0 x8, which provides sufficient bandwidth for the 100 Gbit/s port to operate at line rate.
