Twin10G (Thunderbolt 3 Edition)

Dual-port 10GBASE-T 10 Gigabit Ethernet Thunderbolt 3 Adapter

Blazing-fast 10GBASE-T (Copper) Connectivity Over Thunderbolt 3 for Mac, Windows, and Linux Computers

Increased demand for greater data transfer speeds and more bandwidth on high-performance shared storage networks has driven the explosion in demand for 10 Gigabit Ethernet (10GbE) networking. Yet, most computers aren’t equipped to get you connected. If your computer has a Thunderbolt™ 3 port, you are in luck—Sonnet’s Twin10G™ (Thunderbolt 3 Edition) 10GbE adapter is the powerfully simple and most cost-effective solution for adding blazing-fast dual-port 10GBASE-T 10GbE network connectivity to any Mac®, Windows®, or Linux® computer with Thunderbolt 3 ports.

Sonnet was established in Irvine, California in 1986. Since then, we’ve pioneered and brought to market many innovative and award-winning products that enhance the performance and connectivity of Mac, Windows, and other industry-standard computers. Many of our employees (including engineers) have been with the company for more than 20 years (some have been here since the beginning). We have a wealth of knowledge about our current and past products. Should you ever need technical support on one of our products, contact us; we’ll be around to help you.

Twin10G (Thunderbolt 3) Icon

Small and Nearly Noiseless

The Twin10G (Thunderbolt 3 Edition) adapter is compact enough to easily fit in most workspaces, yet large enough to support proper airflow inside the case—its design enables the adapter’s temperature-controlled, variable-speed fan to keep the adapter running cool and whisper-quiet at all times, making it suitable for use in noise-sensitive environments. Constructed of rugged and lightweight aluminum, the adapter’s outer shell securely protects the inner circuitry.

Simplified Setup

How simple? Just connect the Twin10G (Thunderbolt 3 Edition) adapter to your computer via the included Thunderbolt 3 (40Gbps) cable, download and install a driver, connect the adapter to the network switch or directly to 10GbE-enabled storage via Cat 6 or Cat 6A cables, and configure the adapter’s settings through the macOS® Network control panel, Windows Device Manager, or Linux command line (or graphical utility).

Setup Icons

Intelligent Operation

The Twin10G (Thunderbolt 3 Edition) adapter attains its high throughput performance and low host-CPU utilization through functions such as flow control, 64-bit address support for systems using more than 4GB of physical memory; and stateless offloads such as TCP, UDP and IPv4 checksum offloading. These processes enable your computer to perform better while large files transfers or high I/O operations take place. This Sonnet adapter’s dual 10GbE connections support transparent failover to keep your computer connected in case a single cable is disconnected or one of the ports fails, and also support link aggregation (teaming)(2) for increased throughput!

Thunderbolt 3
The USB-C That Does It All

Thunderbolt  3 ports; the first connects the adapter to your computer, while the second supports daisy-chaining of up to five additional Thunderbolt peripheral devices(3) to a single port on your computer. The Sonnet adapter includes 10Gbps USB  3.1 Gen  2 support, meaning you can connect a USB device(4) to the second port using the proper cable or adapter. The Twin 10G also provides full support for connecting two 4K displays @ 60Hz or one 5K display @ 60Hz(5). For connected devices requiring extra power, 15 watts is provided to connected bus-powered devices(6).

Thunderbolt 3 Cable with ThunderLok 3

Included at No Extra Charge

Thunderbolt 3 Cable. ThunderLok 3.

Sonnet includes a 0.7-meter Thunderbolt 3 (40Gbps) cable and a Sonnet ThunderLok 3 Thunderbolt connector retainer clip(7) to avoid accidental cable disconnections—just slide it over one end of the cable, and then plug in the connector and secure it to the chassis by turning a thumbscrew. Because of its unique design, ThunderLok remains on the cable so it won’t get lost when not in use.
