Product Overview

Upgrading legacy server infrastructure to 10GbE often requires costly cabling changes or complex switch replacements. The LREC9811BT solves this by delivering 10G performance over standard Cat6a copper cabling, enabling a seamless transition from 1GbE without replacing existing network backbone infrastructure.

Built on the Intel X550 controller, this PCIe 3.0 x4 adapter provides 10GBase-T connectivity with NBASE-T support for 2.5/5Gbps speeds over Cat5e. With hardware-accelerated TCP/UDP/IP checksum offloading and SR-IOV support, it significantly reduces CPU overhead, ensuring maximum throughput for virtualized environments and high-load data center applications.

Ideal for enterprise servers, storage arrays, and high-end workstations requiring reliable 10G copper connectivity. The Intel X550 chipset ensures robust driver support across Windows, Linux, and VMware platforms. Choose the LREC9811BT for a cost-effective, low-power upgrade path to 10GbE networking.
