Technical Overview
This Gigabit Ethernet Card utilizes a USB 3.0 host interface, delivering data transfer rates up to 5 Gbps for the USB connection while supporting network speeds up to 1000 Mbps. The single RJ-45 port operates on standard twisted pair Ethernet cabling, compatible with 10/100/1000Base-T networks. Backward compatibility with USB 2.0 and 1.1 host ports ensures functionality across a wide range of computer systems, though at reduced USB speeds.
The adapter's desktop form factor measures 1.20 inches wide by 3.80 inches deep by 0.84 inches high, with a weight of approximately 2.40 ounces. This compact design requires minimal desk space while providing stable Gigabit Ethernet connectivity. The integrated USB hub functionality allows connecting additional USB devices alongside the network connection, though the total number of ports remains one for network purposes.
