BFKK Dual Port Gigabit Network Card Intel I350 SFP PCIe 2.1 x4

SKU CH-R2G6-HV0C2

Dual-port Gigabit SFP adapter with Intel I350 controller on PCIe 2.1 x4 for 1000 Mbps fiber links up to 550 m

  • Dual SFP ports deliver 1.25Gb/s fibre links up to 550m
  • Intel I350 controller provides hardware offloads and on-chip QoS
  • PCIe 2.1 x4 interface runs at 5.0 GT/s for full throughput
  • Broad OS support covers Windows Server 2016, Linux 3.x, FreeBSD 9, VMware ESXi
  • MMF 50µm reaches 550m while 62.5µm reaches 275m

Dual-port SFP network adapter

The BFKK dual-port NIC uses an Intel I350 controller to provide two 1.25 Gb/s SFP connections over a PCIe 2.1 x4 slot. It suits servers or workstations that need fibre uplinks at 1000 Mbps without copper cabling.

Sustained throughput with hardware offloads

The I350 chip handles intelligent offloads, on-chip QoS, traffic management, VMDq and PCI-SIG SR-IOV so that heavy iSCSI or NFS streams keep flowing without burdening the host CPU. Multi-queue design maintains consistent packet processing during prolonged transfers.

Low-profile operation in standard slots

The card draws power from the PCIe 2.1 x4 interface and fits typical low-profile brackets, keeping airflow simple in 1U or 2U chassis. Passive cooling is sufficient for normal loads, and the board supports Wake-on-LAN and PXE boot for remote management.

Questions about this item

How much power does the Intel I350 controller draw when the card runs continuously?

The Intel I350 controller supports Ethernet Power Management and Intelligent Offloads to reduce power draw during sustained operation.

Which SFP transceivers and fibre patch cables must I already own to use the SFP ports?

The card accepts SFP modules for MMF 50 µm fibre up to 550 m and MMF 62.5 µm fibre up to 275 m at 1.25 Gb/s.

Will the PCIe 2.1 x4 interface work in my older PCIe 2.0 x8 or x16 server slot?

Yes, the PCIe 2.1 x4 card is backward compatible with PCIe 2.0 x8 and x16 slots and will operate at 5.0 GT/s.
