Lightning-Fast 10GBASE-T Connectivity Over Thunderbolt 2

With increasing demand for greater data transfer speeds, more bandwidth, and support for 4K video editing via shared storage systems, the need for 10 Gigabit Ethernet (10GbE) networking has skyrocketed. Now that very affordable 10GbE switches with RJ45 (copper) are available, the cost of setting up a 10GbE infrastructure has been significantly reduced. The problem is, most computers aren’t equipped to get you connected. If you have a computer with a Thunderbolt port, Sonnet has a simple solution—the Twin 10G.

inexpensive CAT 6 or CAT 6A copper cabling at distances up to 55 or 100 meters, respectively. This adapter is a powerful and cost-effective way to add dual-port 10GBASE-T connectivity to your Mac® with Thunderbolt 2 or Thunderbolt ports, or Windows® computer with Thunderbolt 2 ports.

Aluminum LogoSmall and Quiet

Measuring just 4 inches wide, by 8.25 inches long, x 2.75 inches high, the Twin 10G is small enough to easily fit in most workspaces. To ensure its operation doesn’t get in the way, the adapter’s temperature-controlled, variable-speed fan keeps the device running cool and whisper-quiet at all times, making it suitable for use in noise-sensitive environments.

Simple Configuration, Advanced Features

The Twin 10G is easy to set up—after connecting to your computer, configure it through the macOS® or OS X® Network control panel, or Windows Device Manager. Further configuration enables you to activate its advanced features: link aggregation (teaming)(1) of its two 10GbE ports increases throughput beyond what a single connection can sustain; transparent failover between 10GbE ports keeps your computer connected in case a single cable is disconnected or one of the ports fails; and jumbo packet (jumbo frame) support can increase throughput and reduce CPU utilization.

10x the Performance of Gigabit Ethernet

This Sonnet solution is perfect for high-performance computing where low latency, high bandwidth, and low CPU overhead are required. Its increased throughput performance and low host-CPU utilization are achieved with stateless offloads, allowing your computer to perform better while large files transfers or high I/O operations take place.

 

Key Features

Adds 10GbE Connectivity—Simple way to add dual RJ45 10 Gigabit Ethernet ports to your Thunderbolt 2- or Thunderbolt-enabled computer

Cost Effective—Connects to 10GbE infrastructure via inexpensive CAT 6 or CAT 6A cables at distances up to 55 or 100 meters, respectively

Mac and Windows Compatible—One-size-fits-many solution for mixed computer environments

Small and Quiet—Compact enough to sit on most any work surface, and quiet enough for use in noise-sensitive environments

Easy Setup—Simple driver installation, configured through OS X or macOS Network control panel, or Windows Device Manager

Supports Link Aggregation (Teaming)—Increases throughput beyond what a single connection can sustain

Supports Transparent Failover—Keeps your computer connected in case a single cable is disconnected or one of the ports fails

Two Thunderbolt 2 Ports—Maximum performance with computers with 20Gbps Thunderbolt 2 technology, works with Mac computers and other devices equipped with 10Gbps Thunderbolt technology. Daisy chain up to an additional five devices.

Thunderbolt Cable & ThunderLok Included—Includes 0.5-meter Thunderbolt cable and ThunderLok Thunderbolt connector retainer clip to secure cable against accidental disconnections

20Gbps Thunderbolt 2 Interface

The Twin 10G features a dual-port 20Gbps Thunderbolt 2 interface that offers ample bandwidth to support the adapter’s high performance, supports daisy-chaining of up to five additional Thunderbolt peripheral devices to a single port on your computer, and includes support for connecting a 4K video monitor. The Twin 10G is also compatible with older Mac computers with 10Gbps Thunderbolt.

Thunderbolt Cable and ThunderLok Included

The Twin 10G adapter includes a 0.5-meter Thunderbolt cable to connect to your computer, and a Sonnet ThunderLok Thunderbolt connector retainer clip(2) to secure the cable to the adapter. The ThunderLok helps prevent accidental cable disconnects that can lead to data loss, securing the Thunderbolt cable to the adapter. ThunderLok is easy to install and use—just slide it over one of the cable’s connectors, plug in the connector, and then secure it to the adapter by turning a thumbscrew. Because the clip doesn’t attach to the connector, it remains on the cable and won’t get lost when not in use.
