Solo10G (Thunderbolt 3 Edition)

10GBASE-T Thunderbolt 3 to 10 Gigabit Ethernet Adapter with NBASE-T Support

Blazing-fast 10GBASE-T Connectivity at a Breakthrough Price

As network bandwidth demands for post-production and shared storage workflows have increased, 10Gb Ethernet has become the new data transfer standard. Very affordable 10Gb Ethernet switches have significantly reduced the cost of setting up a 10GbE infrastructure, resulting in very rapid adoption. Now, for computers with a Thunderbolt 3 port, there is an equally affordable Thunderbolt to 10Gb Ethernet adapter—Sonnet’s Solo10G (Thunderbolt 3 Edition) adapter, a powerfully simple solution for adding blazing-fast 10GBASE-T 10GbE network connectivity to any Mac®, Windows®, or Linux® computer with Thunderbolt 3 ports.


Connect to 10GbE Infrastructure

The Solo10G adapter is equipped with a single RJ45 socket, enabling it to connect to 10GbE infrastructure via inexpensive Cat 6 or Cat 6A copper cabling at distances up to 55 or 100 meters, respectively. Oh, and it’s priced at a level that seemed impossible even a year ago.

Key Features

Adds 10GBASE-T 10GbE Connectivity

Adds an RJ45 10 Gigabit Ethernet port to your computer with Thunderbolt 3 ports.


Low-cost adapter connects to 10GbE infrastructure via inexpensive Cat 6 or Cat 6A cables at distances up to 55 or 100 meters, respectively.

40Gbps Thunderbolt 3 Interface

Connects to any Thunderbolt 3 computer port, or at the end of a Thunderbolt 3 device daisy chain.

Supports NBASE-T Standard

5 Gb/s and 2.5 Gb/s speeds supported over inexpensive Cat 5e (or better) cabling at distances up to 100 meters when used with a multi-Gigabit switch or router.

Advanced Features

Audio Video Bridging (IEEE 802.1Qav, AVB) and Energy-Efficient Ethernet (IEEE 802.3az) supported.

Easy Setup

Configure the adapter's settings using operating system tools.

Small and Silent

Adapter is pocketable and uses no fan, perfect for use in noise-sensitive environments.

Bus-Powered, Energy Efficient

Powered through its Thunderbolt connection, the Solo10G requires no power adapter.

Rugged Construction

Aluminum enclosure withstands heavy use.


Pocketable. Bus-Powered. Silent.

The Solo10G is pocketable—measuring just 3.1 inches wide by 4.5 inches deep by 1.1 inches tall—and bus-powered to enable truly portable use without a power adapter. Wrapping the latest technologies in a rugged aluminum case, Sonnet designed a cool-running adapter that doesn’t need a fan, allowing silent and energy-efficient operation.

Simple Setup

Connect the Solo10G adapter to your computer, and the adapter to the network switch or directly to 10GbE-enabled storage, and then configure the adapter’s settings through the macOS Network control panel, Windows Device Manager(3), or Linux command line (or graphical utility). How’s that for simple?

Advanced Features, Intelligent Operation

The Solo10G (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 supports Energy-Efficient Ethernet (IEEE 802.3az), which reduces the adapter’s power demands on your computer.

AVB Support

Audio Video Bridging (IEEE 802.1Qav, AVB) support makes the adapter perfect for use in pro audio and video applications where synchronization of data streams is critical.(1)

Cat 5E Cables

NBASE-T Support for Faster Transfers Across Existing Cabling

If your facility has Cat 5e wiring installed already, you can still get a great performance gain—from 250 to 500 percent over Gigabit Ethernet speed—without rewiring! The Solo10G adapter supports the NBASE-T™ industry-standard of 2.5/5 Gb link speeds, which enables greater than Gigabit Ethernet speeds over Cat 5e (or better) cabling when used with an NBASE-T compatible (multi-Gigabit) switch or router. Now you can deploy the same adapter across your organization for users supported by different Ethernet cabling infrastructures.

Thunderbolt 3 –

The USB-C That Does It All

Solo10G (Thunderbolt 3 Edition) features a 40Gbps Thunderbolt 3 Interface that connects to any Thunderbolt 3 computer port, or at the end of a Thunderbolt 3 device daisy chain.

Replaceable Captive Cable

‍Through the use of a captive cable, the Solo10G adapter’s Thunderbolt connector remains firmly connected to it at all times. Should the cable ever break, it can easily be replaced with an approved replacement cable available from Sonnet or a Sonnet-authorized reseller.

Safe and Secure

‍ ‍As a networked conduit into your computer, the Sonnet Solo10G was designed with essential security features. Incorporating encryption in hardware, the Sonnet adapter is protected against malicious modification of its firmware. Any unauthorized attempt at firmware modification to facilitate surreptitious computer access would render the adapter inoperable. This secure design prevents the Solo10G adapter firmware from being reprogrammed except by a manufacturer’s update using a secure encryption key.
