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

for computers with Thunderbolt 4 or Thunderbolt 3 ports

Blazing-fast 10GBASE-T (Copper) Connectivity Over Thunderbolt

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 Mac®, Windows®, or Linux® has a Thunderbolt™ 4 or Thunderbolt 3 port, you are in luck — Sonnet’s Twin10G™ 10GbE adapter is the powerfully simple and most cost-effective solution for adding blazing-fast dual-port 10GBASE-T 10GbE network connectivity to any your computer.

Why Thunderbolt 3 Instead of Thunderbolt 4?
Sonnet’s line of Thunderbolt 10GbE adapters rely on Thunderbolt 3 technology for maximum performance. Learn Why ›
Twin10G Icon

Small and Nearly Noiseless

The Twin10G 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 adapter to your computer via the included 40Gbps Thunderbolt 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 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. Windows and Linux also support link aggregation (teaming) for increased throughput!

40Gbps Thunderbolt Cable and ThunderLok 3 Included

Sonnet includes a Thunderbolt cable that supports Thunderbolt’s full 40Gbps bandwidth, and is fully compatible with Thunderbolt 4 and Thunderbolt 3 computers. Sonnet also provides a ThunderLok™ 3 Thunderbolt connector retainer clip that prevents 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.
