Sonnet Technologies ( announced the Twin 10G SFP+ Thunderbolt 2 to Dual-Port SFP+ 10 Gigabit Ethernet (10GbE) adapter, solution for adding 10GbE network connectivity to any Mac with Thunderbolt 2 or Thunderbolt ports.

Featuring 20Gbps Thunderbolt 2 technology, the Twin 10G SFP+ allows users to connect their computers to high-speed network infrastructure and storage systems using the 10GbE standard, which offers up to 10 times the performance of Gigabit Ethernet, the common wired network connection included with many computers.

It’s equipped with two SFP+ sockets, allowing users to select either short-range (up to 300 meters) or long-range (up to 10 kilometers) SFP+ transceivers (sold separately), and connect their computers to a switch or other 10GbE interface via LC fiber optic cables (sold separately) at long distances. Users may also select Twinax direct-attach copper cables for connections up to 10 meters (sold separately). The Twin 10G SFP+ includes two Thunderbolt 2 ports and connects to the computer through an included Thunderbolt cable; the second Thunderbolt port supports daisy-chaining up to six devices to the host computer. 

Measuring just 4 x 8.25 x 2.8 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. The design enables the temperature-controlled, variable-speed fan to keep the adapter cool and run whisper-quiet at all times, making the device well suited for use in noise-sensitive environments. 

The Twin 10G SFP+ will be available Sept. 12 for $669. Short-range 10GBase-SR SFP+ transceivers and long-range 10Base-LR SFP+ transceivers are available for $69 and $149 each, respectively.
