This dual-port 10 Gb PCIe network card offers a versatile & low-cost way to deploy 10 Gb E network connectivity. It adds two copper Ethernet ports to your server or desktop computer & provides Multi-Gigabit Ethernet access to your network at five speeds: 10G, 5G, 2.5G, 1G & 100 Mbps. The 10GBASE-T NIC provides additional bandwidth using your existing Ethernet infrastructure to help reduce the cost of cabling upgrades. The card enables you to connect to 10GBASE-T & NBASE-T equipment at network speeds of: 100 Mbps, 1 Gbps, 2.5 Gbps or 5 Gbps over your CAT5e cabling (up to 100 m); 10 Gbps over your CAT6 or better cabling (up to 100 m). The network adapter card adds two Ethernet ports to your workstation through an x 8 PCIe 2.X (or higher) slot. It features 10GBASE-T technology, supporting advanced Multi-Gigabit systems, including Cisco campus switches & Aruba Networks access points. The NIC card also supports additional features including 9K Jumbo Frames, Autonegotiation, Auto-MDIX & 802.1q VLAN tagging. The dual Tehuti TN4010 + Marvell 88X3110 chipset, compliant with IEEE 802.3az, ensures peak operation & reduced power consumption. The decreased consumption minimizes the heat generated to avoid operating temperatures increasing within your server case.
