Sonnet Twin 10G
Dual-Port 10 Gigabit Ethernet - Thunderbolt 2 Adapter
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.
Small 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.
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.
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.
