200GbE dual-port QSFP112 adapter

The NVIDIA ConnectX-7 MCX753436MS-HEAB is a dual-port network card built for 200GbE and NDR200 InfiniBand links. It targets servers and workstations that need high-bandwidth connectivity over optical fibre. The card uses a PCI Express 5.0 x16 host interface and fits an OCP 3.0 small form factor bracket.

PCIe 5.0 x16 slot and optical cabling

Installation requires a PCI Express 5.0 x16 slot, which also accepts Gen 4.0 and 3.0 links at reduced lane speeds. Dual QSFP112 cages accept optical transceivers for long-distance runs between servers and network gear. Typical draw is 24.5W from the 12V edge connector when passive cables are used, leaving headroom in dense chassis.

High-density clusters and HPC fabrics

This adapter suits builders deploying 200GbE or NDR200 InfiniBand fabrics in compute clusters, storage nodes or AI training rigs. It is not for desktops lacking a full-length x16 slot or QSFP112 optics budget. Buyers needing single-port 100GbE or copper DAC connectivity should evaluate other form factors.

Highlights

  • 200 Gb/s Ethernet throughput with dual QSFP112 ports

  • 5 W typical power with passive cables in Gen 5.0
  • SFF adapter card 115 mm x 76 mm fits dense servers
  • Operating temperature range 0 °C to 55 °C

Questions about this item

At what temperature does the ConnectX-7 MCX753436MS-HEAB throttle under sustained load?

The operational range is 0 to 55 degrees Celsius; sustained operation near the upper limit will trigger thermal protection.

How much power and heat does the MCX753436MS-HEAB produce when running 200 GbE all day?

Typical power is 24.5 W with passive cables in PCIe Gen 5.0 x16; the card relies on server airflow for cooling.

Which host interface and bracket must the server provide for this OCP 3.0 SFF adapter?

It requires a PCI Express 5.0 x16 slot (also compatible with Gen 4.0 and 3.0) and an OCP 3.0 bracket opening.
