This Thunderbolt™ 3 to 10Gb Ethernet adapter connects Thunderbolt 3 enabled devices to a wired Ethernet network, with support for 10Gb/s, 5Gb/s, 2.5Gb/s, 1Gb/s and 100Mb/s Base-T speeds.

Accelerated Network Connection

Increase your data transfer speeds by harnessing the performance of Thunderbolt 3. This Ethernet adapter adds a single RJ45 Ethernet port with 10 Gigabit support to help easily access very large files over the network at increased 10Gbps speeds.

Advanced Technology for Optimal Performance with Thunderbolt 3 

The 5-speed Thunderbolt 3 to 10GbE adapter uses premium chipsets, providing a low-power, high-performance NBASE-T solution. The 10GBASE-T standard supports 10Gbps speeds over existing CAT6a or better cabling at distances of up to 100 m. The Tehuti™ TN4010 controller chipset is compliant with 802.3az Energy Efficient Ethernet and ensures peak operating efficiency with reduced power consumption in bandwidth-intensive workstation applications. 

Quiet & Compact Design

This Thunderbolt 3 NIC is an easy addition to any modern workstation. Taking up only 12 square inches of desk space and fully bus-powered, it's extremely portable with a small footprint. The fanless design means the adapter is noiseless (0dB), so you can set up in an open office space without being disruptive. It’s ideal for virtually any type of workspace or environment, including remote desks and modern open-concept offices. 

This Thunderbolt 3 to 10GbE adapter is backed by a 2-year warranty and free lifetime multilingual technical support.
