10/100/1000Mbps Copper Gigabit PCI Card for PC
Where to buy


High-performance Gigabit Speed
Capable of running at full-duplex Gigabit speed, this card gives your PC 2000Mbps data transmission on your existing Cat. 5 twisted-pair network cable. As an inexpensive alternative solution to fiber-optic, the card allows you to instantly upgrade to Gigabit without requiring you to install new, expensive fiber cables. The card supports 10/100/1000 Mbps network speed auto-sensing and full/half duplex auto-

Priority Queues Support for Quality of Service
With packet prioritization capability, the card allows traffic to be queued as critical and non-critical, permitting your server to run video-conference and multimedia applications where packets are delivered at best-effort speeds.

VLAN to Improve Performance and Security
The card provides on-board screening of VLANs Tagged Ethernet frames, allowing your PC to be configured with a VLAN-supported switch. Your PC can be part of a VLAN network, where domains are segmented up to enhance performance and security.

Flow Control to Minimize Packet Loss
The card's embedded flow control and independent FIFO provides a means to protect against possible data loss during transmission on the network. When connected to a Gigabit switch supporting flow control, the card receives signals from the switch regarding buffer overrun during peak usage periods. The card then delays transmission until the switch is ready again to accept new data.

On-board IP header and IP checksum
IP header and IP checksum of IP network packets are done by the chipset. In Internet, Windows and Unix environments, this serves well by offloading the host's overheads to enhance the network performance.
