  • High-performance RTL8159 chipset enables stable 10GbE data transfer at 1.95W typical power
  • Backward compatible with 2.5GbE, 5GbE and 1GbE networks for versatile connectivity
  • Plug-and-play USB-C setup requires no external power and works with major operating systems

10Gbps USB-C Ethernet Adapter

The Fervit USB-C to 10Gbps Ethernet Adapter uses the RTL8159 chipset to add a 10000Mbps wired network port to USB4 or Thunderbolt 3/4 hosts. It supports 10, 5, 2.5 and 1GbE speeds with a typical power draw of 1.95W and requires no external power supply.

Check host port and cabling

Verify your device has a USB-C port that supports USB4 or Thunderbolt 3/4 to reach the highest speeds. An Ethernet cable is not included, so source a Cat 6a or better cable for 10GbE links. Mac users should note Thunderbolt connections are limited to 5Gbps by the operating system.

Suits portable 10GbE upgrades

Ideal for laptop, desktop or NAS users who need a compact, bus-powered 10GbE link without installing a PCIe card. Buyers whose only ports are USB 3.2 Gen 2 or earlier will not reach 10Gbps. Anyone needing Power over Ethernet or a multi-port switch should look elsewhere.

Questions about this item

What cables are included with the Fervit RTL8159 adapter and what must I provide myself?

A USB-C cable is supplied in the box for connecting the adapter to your host; you will need to supply your own Ethernet cable to reach the network.

Which multi-gigabit speed should I select if my switch only supports 2.5GbE?

The adapter automatically negotiates down to 2.5GbE, so you can use it immediately without any manual configuration.

What does the 10Gbps headline rate mean when the adapter is plugged into a Thunderbolt 3 port on a Mac?

On macOS the Thunderbolt 3 connection is limited to 5Gbps, so the 10Gbps maximum is only reached on hosts that fully support USB4 or Thunderbolt 4.
