(Irvine, CA--February 9, 2017) Sonnet Technologies today announced the Twin 10G™ Thunderbolt™ 3 Edition Thunderbolt 3 to Dual-Port 10GBASE-T 10 Gigabit Ethernet (10GbE) adapter, and the Twin 10G SFP+ Thunderbolt 3 Edition Thunderbolt 3 to Dual-Port SFP+ 10GbE adapter. Both are cost-effective solutions for adding lightning-fast 10GbE network connectivity to any Mac® or Windows® computer with a Thunderbolt 3 port, and they enable users to easily connect their computers via copper or optical cables to high-speed network infrastructure and storage systems using the 10GbE standard. Their performance, compact size, easy setup, and quiet operation make these Sonnet adapters suitable for use in a variety of workflows and environments.

The Twin 10G Thunderbolt 3 adapter is equipped with two RJ45 ports, enabling users to connect their computers to a switch or other 10GbE interface via inexpensive CAT-6 or CAT-6A copper cabling at distances up to 55 or 100 meters, respectively.

The Twin 10G SFP+ Thunderbolt 3 adapter is 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 cost-effective Twinax direct-attach copper cables for connections up to 10 meters (sold separately).

"We have experienced tremendous success with our current line of fast 10Gb Ethernet to Thunderbolt 2 adapters in areas such as HD video editing with high-bandwidth shared storage systems, and the demand for 10GbE adapters continues to grow," said Robert Farnsworth, CEO of Sonnet Technologies. "It was a natural evolution to introduce our Thunderbolt 3 Edition Twin 10G adapters that provide users with powerfully simple and cost-effective options to add fast copper or optical 10GbE connectivity through their computers' Thunderbolt 3 ports."

Featuring the latest Intel® 10 Gigabit Ethernet controllers, these Sonnet adapters are tuned for maximum I/O operation and are perfect for high-performance computing where low latency, high bandwidth, and low CPU overhead are required. For ease of use, the Sonnet adapters are configured through the macOS™ Network control panel or Windows Device Manager. Both Twin 10G Thunderbolt 3 Edition models feature dual 40Gbps Thunderbolt 3 ports that support the daisy chaining of up to five additional Thunderbolt peripheral devices.

Each measuring just 4 inches wide by 8.25 inches long by 2.8 inches tall, Twin 10G Thunderbolt 3 adapters are small enough to sit on most any work surface, but large enough to support adequate airflow inside their cases. Designed to enable the temperature-controlled, variable-speed fan to keep the adapter cool and run whisper-quiet at all times, the devices are well suited for use in noise-sensitive environments.

The Twin 10G Thunderbolt 3 Edition (part number TWIN10GC-TB3) and Twin 10G SFP+ Thunderbolt 3 Edition (part number TWIN10GC-SFP-TB3) are available now for $669 USD each. Short-range 10GBASE-SR SFP+ transceivers (part number G10E-SFP-SR) and long-range 10BASE-LR SFP+ transceivers (part number G10E-SFP-LR) are available for $69 and $149 each, respectively.
