Twin10G SFP+ (Thunderbolt 3 Edition)

Dual-port SFP+ 10 Gigabit Ethernet Thunderbolt 3 Adapter

Blazing-fast 10GbE Connectivity Over Thunderbolt 3 for Mac, Windows, and Linux Computers

Are you looking for the most economical dual-port approach to connecting to a high-speed 10 Gigabit Ethernet (10GbE) fiber network using the Thunderbolt 3 port on your computer? You’ll need an adapter. Sonnet’s Twin10G™ SFP+ (Thunderbolt™ 3 Edition) adapter is the powerfully simple solution for adding blazing-fast dual-port 10GbE network connectivity to any Mac®, Windows®, or Linux® computer with Thunderbolt 3 ports.

Flexibility of SFP+ Transceiver Choices

Sonnet offers three SFP+ transceiver options (sold separately)—a short-range multi-mode fiber module (up to 300 meters), part number G10E-SFP-SR; a long-range single-mode fiber module (up to 10 kilometers), part number G10E-SFP-LR; and a 10GBASE-T copper module, part number G10E-SFP-T (CAT 6A cable up to 30 meters). Alternatively, you can use cost-effective direct-attach Twinax copper cables up to 10 meters long (sold separately).

More Bandwidth

Equipped with two SFP+ sockets, the Twin10G SFP+ (Thunderbolt 3 Edition) adapter supports ten times the performance of Gigabit Ethernet and more bandwidth over shared networks.

Compact and Nearly Noiseless

Small enough to easily fit in most workspaces, the Twin10G SFP+ (Thunderbolt 3 Edition) adapter is still 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.

Easy to Set Up

Simply connect the Twin10G SFP+ (Thunderbolt 3 Edition) adapter to your computer via the included Thunderbolt 3 (40Gbps) cable, download and install a driver, install SFP+ module(s) (sold separately), connect the adapter to the network switch or directly to 10GbE-enabled storage, and configure the adapter’s settings through the macOS® Network control panel, Windows Device Manager, or Linux command line (or graphical utility).

Intelligent Operation

The Twin10G SFP+ adapter’s high throughput performance and low host-CPU utilization are attained 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 operations 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.

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(6) 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.
