Green PCB plug-in card with two silver SFP+ cages and gold PCIe x8 edge connector

Axiom

Axiom E10G42BFSR-AX 10GBase-SR dual-port SFP+ PCIe 2.0 x8 network card

SKU CH-0CN8-KX4HC MPN E10G42BFSR-AX

Dual-port 10GBase-SR SFP+ card installs in a PCIe 2.0 x8 slot and includes transceivers for short-range fibre links

  • Changer TypeSFP+
  • Dual 10GBase-SR ports deliver high-speed fibre connectivity
  • PCIe 2.0 x8 host interface provides ample bandwidth for both ports
  • Two SFP+ cages accept compatible optical transceivers
  • Low-profile 6.5" x 2.7" form factor fits dense server chassis
  • Lightweight 4.96 oz design reduces mechanical stress on the slot

Dual 10GbE SFP+ card for servers

The Axiom E10G42BFSR-AX installs in a PCI Express 2.0 x8 slot and presents two SFP+ cages for 10GBase-SR optical fibre links. It targets administrators adding short-range 10 Gb connectivity to rack-mount servers that already have an x8 lane budget.

Bandwidth capped by PCIe 2.0 x8

The host interface limits aggregate throughput to roughly 4 GB/s, so simultaneous line-rate traffic on both ports will saturate the bus. Builds that need sustained dual-port wire speed should verify the platform can allocate a full x8 gen 2 link or consider a newer generation slot.

Low-profile bracket with transceivers included

A 6.5 by 2.7 inch plug-in card weighing 4.96 oz fits 1U chassis without blocking adjacent slots. The SFP+ cages accept standard SR modules and the package ships with transceivers, so the links are operational immediately after driver installation.

Questions about this item

Should I pick the dual-port SFP+ card or a single-port version?

The E10G42BFSR-AX provides two SFP+ ports on one PCIe 2.0 x8 card, so you get two 10GBase-SR links without using a second slot.

What throughput will I actually see from the 10GBase-SR ports?

Each port runs at 10 Gb/s line rate over multimode fibre, and the PCIe 2.0 x8 host interface supplies enough bus bandwidth for both ports at full speed.

What does the PCIe 2.0 x8 interface limit in practice?

The card plugs into any PCIe 2.0 x8 or larger slot; the x8 electrical connection sets the maximum bus bandwidth available to the two SFP+ ports.
