1. This gigabit network card uses a half-height MINI PCI-Express slot to expand a high-performance 10, 100, 1000 Base-T gigabit Ethernet interface2. The transmission rate of connecting 4 groups of twisted-pair steel network cables can reach gigabit, and the distance can reach 100 meters.3. It is 100% fully backward compatible with 10/100Mbps systems. Can be used on any existing network.4. Native MINI PCI-Express gigabit network card chip, supporting existing CAT-5 UTP network wiring5.
