Dual-port gigabit SFP PCIe x4 server adapter based on Intel 82576 controller.
When legacy server infrastructure requires reliable fiber connectivity without consuming high-bandwidth PCIe lanes, efficient slot utilization becomes critical for data center density.
The LREC9702EF-2SFP network adapter delivers 1Gbps per port via dual SFP interfaces on a PCIe v2.0 x4 bus, ensuring compatibility with x8 and x16 slots while maintaining low 3.6W power consumption to reduce thermal load in dense rack environments.
Ideal for secure enterprise networks requiring independent controllability, this Intel 82576-based card supports IEEE 1588 PTP and DPDK for precise timing and packet processing. It provides a stable, cost-effective fiber uplink solution for virtualization and storage networking applications.
Developed based on the Intel 82576 master control solution with independent intellectual property rights.
Two 1G SFP ports supporting 1000Base-SX/1000Base-LX fiber connections for flexible deployment.
Operates on PCIe v2.0 x4 bus with backward compatibility for x8 and x16 channels.
Efficient design with only 3.6W power consumption supplied directly via PCIe slot.
Supports PXE, DPDK, WoL, iSCSI, Jumbo Frames, and IEEE 1588 PTP for enterprise applications.
