Lightning-Fast 10GbE Over Thunderbolt 2

Do you need a simple and cost-effective way to connect your computer to a high-speed 10 Gigabit Ethernet (10GbE) network? By offering ten times the performance of Gigabit Ethernet and more bandwidth over shared networks, and by supporting specialized applications such as using high-performance shared storage systems for editing HD video, it’s no wonder that 10 Gigabit Ethernet use has skyrocketed—the problem is that the vast majority of computers don’t include a native connection. Sonnet’s Twin 10G SFP+ 10GbE adapter is the powerfully simple solution for you to add lightning fast 10 Gigabit Ethernet network connectivity to any Mac® with Thunderbolt 2 or Thunderbolt ports, or any Windows® PC with a Thunderbolt 2 port.

Small. Light. Quiet.

Measuring a scant 4 inches wide by 8.25 inches long by 2.75 inches tall, the Twin 10G SFP+ 10GbE adapter is small enough to sit on most any work surface, but large enough to support adequate airflow inside the case and enable its temperature-controlled, variable-speed fan to keep the adapter running cool, whisper-quiet at all times. Constructed of rugged and lightweight aluminum, the outer shell securely protects the inner circuitry.

Simple Setup, Smart Performance

Setup is easy—connect the Twin 10G SFP+ 10GbE adapter to the host computer via the included Thunderbolt cable, download and install a driver, connect the adapter to the switch or device’s 10GbE ports via LC fiber optic cables (SFP+ transceivers and fiber optic cables sold separately), or SFP+ direct-attach copper cables (sold separately), and then configure the adapter through the OS X® Network control panel or Windows Device Manager. The second Thunderbolt 2 port supports daisy chaining, supporting the connection of up to six devices to a single port on the host computer.

Bandwidth & CPU UsageThis Sonnet adapter’s increased throughput performance and low host-CPU utilization are achieved with functions such as flow control support, 64-bit address support for systems using more than 4GB of physical memory; and stateless offloads such as TCP, UDP and IPv4 checksum offloading, enabling your computer to perform better while large files transfers or high I/O operations take place. With its dual ports, the Sonnet adapter supports transparent failover to keep your computer connected in case a single cable is disconnected or one of the ports fails, and it also supports link aggregation(1) for increased throughput!

Key Features

Adds High-Performance 10GbE SFP+ Connectivity—Powerfully simple way to add two 10GbE SFP+ connections to your Mac with Thunderbolt 2 or Thunderbolt ports, or Windows PC with a Thunderbolt 2 port

Connection Flexibility—Choose two short-range or two long-range SFP+ transceivers plus LC fiber optical cables (all sold separately), or two SFP+ direct-attach Twinax copper cables (sold separately) to connect the Twin 10G SFP+ 10GbE adapter to your network or storage

Compact and Light—Adapter is small enough to sit on most any work surface

Remarkably Quiet—Temperature-controlled, variable-speed fan automatically and quietly cools the adapter

Rugged Aluminum Housing—Provides robust and secure protection for any environment

Upgradeable—When available, upgrade to 40Gbps Thunderbolt 3 Technology with a replacement Thunderbolt 3 interface card

Easy Setup—Configured through OS X Network control panel or Windows Device Manager

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

Supports Link Aggregation (Teaming)—Increases throughput beyond what a single connection can sustain(1)

Two Thunderbolt 2 Ports—Daisy chain up to six devices to a single port on the host computer

Flexibility of Short-Range or Long-Range SFP+ Transceivers

Sonnet offers two SFP+ transceiver options (sold separately)—a short-range module (up to 300 meters, part number G10E-SFP-SR), and a long-range module (up to 10 kilometers, part number G10E-SFP-LR)—that connect the Twin 10G SFP+ via LC fiber optical cables (sold separately) to a network switch or storage. Alternatively, you can use cost-effective direct-attach Twinax copper cables up to 10 meters long (sold separately).

Thunderbolt Cable & ThunderLokThunderbolt Cable and ThunderLok™ Included

Sonnet includes a Thunderbolt cable to connect the Twin 10G SFP+ 10GbE adapter to your computer, and a ThunderLok Thunderbolt connector retainer clip(2) to secure the cable to the Twin 10G adapter. Thunderbolt connectors are held in place by friction, which works well in situations where equipment remains undisturbed while operating. But when there’s a chance of movement nearby, there’s a chance the Thunderbolt cable can be unintentionally unplugged, possibly leading to loss of your work or data. Sonnet’s ThunderLok prevents accidental cable disconnections from the Echo chassis, and is easy to install and use—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 does not attach to the connector, but remains on the cable so it won’t get lost when not in use.
