Adaptability and heat dissipation: Comes with standard brackets and slim brackets for different applications such as desktops, workstations, servers, and mini-tower computers. Excellent heat dissipation performance can quickly reduce the temperature and keep the stability of network transmission.Network Interfaces: Two independent Ethernet interfaces for 10GBASE-T, 1000BASE-T, 100BASE-TX applicationgs (IEEE 802.3an, 802.3,802.3u, and 802.3ab), supports Windows/Windows Server/Linux/Vmware/ESX.Customer service Every 10G NIC is rigorously tested for reliability, quality, and performance. We supply a year warranty for whole products and lifetime technical support.PCIe to 10Gbe RJ45: This 10G BASE-T PCIe network adapter converts PCIe slots (X8/16) into 10G RJ-45 Ethernet ports. Note: Only for PCIe ports, not for PCI slots.10G Network Card Adopting Intel X540 Controller, it provides up to Dual Lan 10 Gbps of extreme speed to ensure the stability of Internet access and local data transmission, effectively preventing packet loss and making the server more stable.
