Blazing-fast 10GBASE-SR Connectivity

Most post-production shared storage workgroups and other bandwidth-intensive workflows have been rapidly transitioning to 10Gb Ethernet as the new data transfer standard. For many, the 10Gb Ethernet network infrastructure of choice is optical (SFP+) 10Gb Ethernet. For these workgroups, there is now an affordable 10GbE interface for your Mac® or Windows® computer with Thunderbolt™ 3 ports—Sonnet’s Solo10G™ SFP+ (Thunderbolt 3 Edition) adapter, a powerfully simple solution for adding blazing-fast fiber optic 10GbE network connectivity.


Connect to 10GbE Infrastructure

The Solo10G SFP+ (Thunderbolt 3 Edition) adapter includes a 10GBASE-SR (short-range) SFP+ transceiver (the most commonly-used optical transceiver), enabling you to connect your computer to 10GbE infrastructure via LC optical cable (optical cables sold separately) at distances up to 300 meters.


Advanced Features, Intelligent Operation

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


Additional SFP+ Transceiver Choices

Sonnet includes a short-range multi-mode fiber SFP+ module (up to 300 meters), part number G10E-SFP-SR, with the Solo10G adapter. Sonnet also offers a long-range single-mode fiber module (up to 10 kilometers), part number G10E-SFP-LR (sold separately); and a 10GBASE-T copper module (up to 30 meters using Cat 6A cables), part number G10E-SFP-T (sold separately). Alternatively, you can use cost-effective direct-attach Twinax copper cables up to 10 meters long.


Pocketable. Bus-Powered. Silent.

Unlike most 10GbE adapters, the Solo10G SFP+ is pocketable—measuring only 3.1 inches wide by 4.9 inches deep by 1.1 inches tall—and bus-powered to enable truly portable use without a power adapter. Designed using the latest technologies, and wrapped in a rugged aluminum case, the Sonnet adapter is cool running and 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, or Linux command line (or graphical utility).


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 SFP+ 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.
