Fervit USB-C to 10GbE Ethernet Adapter RTL8159

SKU CH-A6J3-E3D4A

Adds a 10 Gigabit Ethernet port via USB-C using the RTL8159 chip with 2.5 and 5 GbE fallback, 1.95 W draw and LED status lights

  • Adds a 10 GbE port over USB-C with RTL8159 chipset
  • Backward compatible with 2.5 GbE and 5 GbE networks
  • Works through Thunderbolt 3, 4 and 5 ports
  • Plug-and-play with included USB-C cable and no external power
  • Low 1.95 W power draw in aluminum housing for heat dissipation

Fervit 10GbE USB-C Adapter

The Fervit USB-C to 10GbE adapter uses the RTL8159 network chipset to add a 10000Mbps Ethernet port to desktops, laptops and portable gaming systems. It delivers high performance with a typical power draw of 1.95W and backward-compatible 2.5GbE, 5GbE and 1GbE speeds. An aluminium housing aids heat dissipation during sustained transfers.

Host USB-C Port Requirements

Your host must provide a USB4 or Thunderbolt 3/4/5 Type-C port to reach the 10Gbps link rate; a USB3.2 Gen2 port is also required for the full 10GbE throughput. The adapter draws power from the bus so no external supply is needed, but the port must supply sufficient current for 1.95W operation. An Ethernet cable is not included and must be sourced separately. MAC users should note that Thunderbolt connections are currently limited to a 5G negotiated rate.

Upgrade from 1GbE or Slower

This adapter replaces a built-in 1GbE port or a slower USB-Ethernet dongle when you need multi-gigabit wired throughput for NAS access, large file moves or low-latency gaming. The jump is worthwhile when your switch, router or NAS already supports 2.5GbE, 5GbE or 10GbE and your host has the required USB4 or Thunderbolt interface. It does not suit buyers who need more Ethernet ports or who lack a compatible high-speed USB-C port.

Questions about this item

Does the adapter come with an Ethernet cable or do I need to buy one separately?

The package includes a USB-C cable for host connection. An Ethernet cable is not included and must be purchased separately.

Which network speeds does the RTL8159 chipset actually support on this adapter?

The RTL8159 chipset supports 10, 5, 2.5 and 1 GbE speeds, so it works with 10GbE, 5GbE, 2.5GbE and standard Gigabit networks.

What real-world throughput can I expect when the adapter is connected to a USB3.2 Gen2 port?

USB3.2 Gen2 provides a 10 Gbps theoretical ceiling; the adapter can negotiate 10GbE, but actual throughput depends on the host, cabling and network equipment.
