Axiom

Axiom PCIE4-M2QSFP56-AX 200Gbps dual-port QSFP56 PCIe 4.0 x16 adapter

SKU CH-1Q3Y-HYF5B MPN PCIE4-M2QSFP56-AX

Dual-port QSFP56 adapter delivers 200 Gbps wired Ethernet over PCIe 4.0 x16

  • 200 Gbps throughput per port for high-bandwidth workloads
  • Dual QSFP56 ports enable redundant or aggregated links
  • PCIe 4.0 x16 interface delivers full 200 Gbps line rate
  • Plug-in card form factor fits standard server slots
  • Wired connectivity ensures consistent low-latency performance

Dual 200 Gbps QSFP56 connectivity

This Axiom network adapter installs in a PCIe 4.0 x16 slot and provides two QSFP56 ports rated at 200 Gbps each. It is built for servers and workstations that need high-throughput wired links for storage clusters, high-performance computing or dense virtualization hosts.

Verify slot width and cabling before ordering

Confirm the host system has a free PCIe 4.0 x16 slot with enough physical clearance for a full-height plug-in card. Ensure you have compatible QSFP56 transceivers or direct-attach cables rated for the 200 Gbps data rate, as the adapter ships without optics.

Replaces single-port or slower 28 Gbps

Moving from a single-port card or from 28 Gbps and 56 Gbps links doubles both port count and per-port bandwidth, cutting latency in east-west traffic. The jump is worthwhile when workloads saturate existing links or when rack density demands fewer cables for the same aggregate throughput.

Questions about this item

Does the box include QSFP56 transceivers or cables for the two ports?

The adapter ships as the card only; QSFP56 transceivers or direct-attach cables must be purchased separately for each of the two ports.

Should I pick a 28 Gbps or 56 Gbps lane speed variant for 200 Gbps total throughput?

The card uses four 56 Gbps lanes per port to reach 200 Gbps aggregate; there is no 28 Gbps lane option for this model.

Will a PCIe 4.0 x16 slot deliver the full 200 Gbps across both ports at once?

The x16 4.0 interface provides enough bandwidth for both 200 Gbps Ethernet ports to run at line rate simultaneously.
