Integrated 10/100 / 1000M Ethernet Adapter card

For PCI Express applications


PCI Express Gigabit EthernetCard is a high performance 10/100/1000 BASE-T Ethernet LAN controller which designed by RTL8111E chipset, 

is perfectly for home and office use. It provides a low cost solution for connecting to a high speed Local Area Network with a data transfer rate up to 1000Mbps over a group of 4 twisted pair copper wires to a distance of maximum 100 meters away. It is 100 times faster than, and yet 100% fully backward compatible with 10/100BASE-T system, therefore, it can be easily plugged into almost any existing network with CAT-5 cabling.
