Thunder3 10G Network Adapter

The Thunder3 10G Network Adapter offers a portable, bus powered, fanless and low-cost 10GbE solution enabling 10GBase-T and NBASE-T (IEEE 802.3bz-2016) connectivity for Apple® OS X® and Microsoft® Windows® environments over Thunderbolt™. This network adapter is ideal for Thunderbolt 3 capable notebooks like the MacBook Pro (late 2016) and professional workstations that require reliable, accelerated access to external storage and networks for I/O demanding applications.

  • Thunderbolt 3 interface with reversible USB-C connector
  • Ethernet port supports auto-negotiation for 10Gb/s, 5Gb/s, 2.5Gb/s, 1Gb/s and 100Mb/s Base-T
  • Large gaps for air flow and heatsink for passive cooling
  • Bus powered 10GbE network adapter
  • Jumbo frame support (9K)
  • Durable, compact and portable
  • Protective rubber sleeve

10GBase-T connectivity over Thunderbolt™ 3

The 10G network adapter utilizes a simplified design for high speed, 10GbE networking for modern workstations and ultrabooks which typically lack 1GbE connectivity or the capability to deploy an internal PCIe 10GbE network card (NIC), but may be equipped with a Thunderbolt™ 3 connector capable of delivering up to 40Gbps.

The Ethernet port supports auto-negotiation for 10Gb/s, 5Gb/s, 2.5Gb/s, 1Gb/s and 100Mb/s, making this a very flexible solution for any environment.

Bus Powered 10GbE Network Adapter

Compact, Portable and Bus Powered

The Thunder3 10G Network Adapter provides an extremely portable 10 Gigabit Ethernet solution. This sleek and compact adapter runs on bus power alone. The rugged aluminum housing with its unique heatsink design and open gaps for air flow can dissipate the heat and keep the device cool all without any noise whatsoever. Hassle-free with its reversible Thunderbolt 3 (USB-C) cable, simply plug in the device, install the driver and you are set to go.

Portable 10GbE Network Adapter


This test is intended as a reference only. Real world results will vary depending on the network environment, the storage devices and the computers that are used.

10GbE Network Performance

In the example below with Windows 10, iperf3 was used to measure the performance, showing the results for both send and receive in the task manager. Please note that the tranfer rates when copying actual files will likey be different from this benchmark result, because for this test, the benchmark was the only program running and all other software like anti-virus scanner and firewalls were turned off.

  • This Thunderbolt product is not compatible with Apple's Boot Camp.

  • High quality Cat-6A Ethernet cable is recommended for distances up to 100m. At shorter cable length, it's possible to use cables of lower grade (e.g. Cat-6 for 10G or Cat-5e for 5G up to 55m).

  • To use this bus-powered device on older Thunderbolt and Thunderbolt 2 computers, it has to be connected to the second Thunderbolt 3 port on another self-powered Thunderbolt 3 device. If connected directly to the Thunderbolt 3 to Thunderbolt 2 adapter, bus-power is insufficient. A possible setup might look like this: TB2 Mac with macOS 10.13.4 or above > TB3 to TB2 adapter from Apple > self-powered TB3 device with two TB3 ports > TB3 10G adapter.

The AKiTiO Thunder3 10G (T3NA-T3LNITY-AKT) network adapter supports five speeds, including 10GBase-T as well as NBase-T, allowing it to work not only with corporate 10 GbE networks, but also with upcoming 2.5GBase-T and 5GBase-T networks primarily aimed at small businesses and consumers, as well as existing 1 GbE and 100 M networks. The device itself is a relatively small rugged box made of aluminum for better heat dissipation and featuring rubber pads on its sides for further protection. Read More...
