LR-LINK LREC9710HF-SFP 1G PCI-E X4 NIC network card

Simplex fibre NIC for secure environments

The LR-LINK LREC9710HF-SFP is a gigabit Ethernet adapter that uses single-strand fibre to enforce physical separation between internal and external networks. It targets government, military and public-safety systems where data confidentiality is mandatory. The card plugs into a PCIe x4 slot and is driven by an Intel I350AM2 controller. Supported operating systems include Windows, Windows Server, Linux SLES and VMware.

Sustained throughput with physical isolation

Simplex optical transmission removes the return path, so traffic cannot leak back across the link and packet loss stays low during continuous loads. The Intel I350AM2 offloads checksum and segmentation tasks, keeping CPU utilisation steady when the line runs at full gigabit speed for long periods. Third-party security software can further shape or audit the one-way flow without interrupting the stream.

Low-profile bracket and single LC port

A half-height bracket fits 1U and blade chassis without blocking adjacent slots. The lone LC connector accepts standard simplex patch cords, so cable routing stays simple in dense racks. No copper ports are present, eliminating accidental bridging of the isolated domains. The board draws power solely from the PCIe slot, requiring no external supply.
