The D-Link DXE-810S 10 Gigabit Ethernet SFP+ PCI Express Adapter is a high performance adapter designed for the high-speed PCI Express bus architecture. It offers increased bandwidth, reliability, and more functionality than standard PCI network cards. It is specifically designed to allow throughput at rates up to 20 Gbps, thus eliminating the bottleneck that exists with current 32 and 64-bit PCI bus architectures.
