Dual-port 10GbE copper network adapter based on Intel X550 chipset for servers and workstations.
The LREC9812BT is a robust dual-port 10 Gigabit Ethernet network adapter independently developed by LR-LINK, leveraging the industry-standard Intel X550 chip. This PCIe v3.0 x4 adapter is fully compatible with PCIe x8 and x16 slots, making it an ideal upgrade solution for high-end servers, workstations, and data center infrastructure requiring reliable copper connectivity.
Equipped with two integrated 10GBASE-T copper PHYs, this network adapter supports NBASE-T technology, allowing flexible speeds of 2.5 Gbps and 5.0 Gbps over existing Cat 5e cabling, while delivering full 10 Gbps performance over Cat 6a or higher. It ensures backward compatibility with 100/1000 Mbps networks, simplifying network transitions and reducing deployment costs.
To maximize system efficiency, the LREC9812BT integrates advanced hardware acceleration capabilities. It performs TCP/UDP/IP checksum offloading and TCP segmentation offload (TSO), significantly reducing host CPU utilization. This allows the processor to focus on critical applications, enhancing overall server performance in multi-network and high-performance computing environments.
Delivers 10Gbps throughput with support for 2.5G and 5G NBASE-T speeds over copper.
Powered by the trusted Intel X550 controller for stable enterprise-grade performance.
Hardware offloading reduces CPU load, freeing resources for critical applications.
Dual RJ45 ports support standard Cat 6a cabling for easy integration into existing infrastructures.
Optimized for servers and workstations with SR-IOV, PXE, and Jumbo Frame support.
