USB 3.0 to Gigabit Ethernet converter

The Nippon Labs 30U3-20-AX179 adds a wired 1Gbps network port to any computer with a free USB 3.0 Type A socket. It draws power from the bus and requires no external supply. The white enclosure houses an on-chip PHY and controller compliant with USB Spec 3.0, 2.0 and 1.1.

Suitable for laptops or desktops missing

Systems that only offer USB 2.0 ports will be limited to lower speeds, and users needing multi-gigabit throughput should consider other solutions. The adapter supports Windows XP, Vista, 7 and above plus Mac OS X 10.4 or above.

On-chip USB 3.0 PHY with Energy Efficient Ethernet

The integrated controller handles super, high and full speed modes with automatic bus-power or self-power detection. It supports IEEE 802.3az for reduced power consumption during low-link utilisation. Parallel detection and automatic polarity correction simplify cable installation.

Questions about this item

Should I choose the USB 3.0 version or would a USB 2.0 model be enough for Gigabit Ethernet?

The adapter uses a USB 3.0 Type A male connector that supports super, high and full speed modes, so it can deliver the full 1Gbps Ethernet rate; a USB 2.0 port would limit throughput to the bus maximum.

What does the 1Gbps Ethernet rating mean when the adapter is plugged into my laptop?

The RJ-45 port is rated at 1Gbps and the on-chip USB 3.0 PHY complies with USB Spec 3.0, 2.0 and 1.1, allowing the link to run at Gigabit speed when connected to a USB 3.0 host.

Which USB standard does the converter use and what speed does that cap in practice?

It uses a USB 3.0 Type A male connector compliant with USB Spec 3.0, 2.0 and 1.1, so the practical ceiling is the USB 3.0 bus bandwidth for super-speed operation.
