Two 2.5G ports for fast network upgrade

More performance per port:2.5 Gb/s accelerate local transfers compared to 1G. Flexible network separation:Two independent RJ45 ports for segmented networks or services. Installation in many systems:PCIe x1 with standard and low-profile bracket for desktop cases of any form factor. Stable transmission and lower CPU load:Jumbo frames up to 16 KB, flow control as well as checksum and segmentation offloads. Automatic adaptation in operation:Auto-Negotiation 10/100/1000 Mb/s and 2.5 Gb/s plus crossover detection.

The dual-port PCIe network card adds two 2.5G Ethernet interfaces to your PC for higher transfer rates on the local network. Offload functions for checksums and segmentation reduce CPU load, while full-duplex flow control enables consistent data transfer. In professional IT environments and existing infrastructures, IEEE 802.1Q VLAN tagging and 802.1p prioritization facilitate the separation and prioritization of traffic. The included low-profile bracket also allows installation in compact cases for on-site installations and service deployments; driver support for Windows and Linux supports use in companies and public institutions.

Connection:2x RJ45 Interface:PCI Express x1, Revision 2.1 Data rate:10/100/1000 Mb/s and 2.5 Gb/s (Auto-Negotiation) Duplex:Full-duplex flow control (IEEE 802.3x) Jumbo frame:up to 16 KB QoS/VLAN:IEEE 802.1p, IEEE 802.1Q Standards:IEEE 802.3, IEEE 802.3u, IEEE 802.3ab Functions:crossover detection and auto-correction, checksum offload (IPv4, IPv6, TCP, UDP), segmentation task offload (Large Send v1/v2) Chipset:Realtek RTL8125B Compatibility:Windows 11/10/8.1/8/7 32/64-bit, Linux Scope of delivery:Dual 2.5G Ethernet card PCI-E, low-profile bracket, driver CD, manual
