Are you looking for a straightforward and economical approach to connecting your computer to a high-speed 10 Gigabit Ethernet (10GbE) network using the Thunderbolt 3 port on your computer? You’ll need an adapter. Delivering up to ten times Gigabit Ethernet’s performance and supporting uses such as HD video editing on high-performance shared storage systems, it’s no wonder that 10GbE use has soared. Sonnet’s Twin 10G™ SFP+ 10GbE Thunderbolt 3 adapter is the powerfully simple solution for adding blazing-fast 10GbE network connectivity to any Mac® or Windows® computer(1) with Thunderbolt 3 (USB-C) ports.
Sonnet offers three SFP+ transceiver options (sold separately)—a short-range multi-mode fiber module (up to 300 meters), part number G10E-SFP-SR; a long-range single-mode fiber module (up to 10 kilometers), part number G10E-SFP-LR; and a 10GBASE-T copper module, part number G10E-SFP-T (Cat 6A cable up to 100 meters). Alternatively, you can use cost-effective direct-attach Twinax copper cables up to 10 meters long (sold separately).
Simply connect the Twin 10G SFP+ Thunderbolt 3 adapter to your computer via the included Thunderbolt 3 (40Gbps) cable, download and install a driver, install SFP+ module(s) (sold separately), connect the adapter to the network switch or directly to 10GbE-enabled storage, and configure the adapter’s settings through the macOS™ Network control panel or Windows Device Manager.
Connect your computer to the switch or device’s 10GbE ports via inexpensive CAT-6 or CAT-6A copper cabling
The Twin 10G SFP+ Thunderbolt 3 adapter’s high throughput performance and low host-CPU utilization are attained through functions such as flow control, 64-bit address support for systems using more than 4GB of physical memory; and stateless offloads such as TCP, UDP and IPv4 checksum offloading. These operations enable your computer to perform better while large files transfers or high I/O operations take place. This Sonnet adapter’s dual 10GbE connections support transparent failover to keep your computer connected in case a single cable is disconnected or one of the ports fails, and also support link aggregation(3) for increased throughput!
Small enough to easily fit in most workspaces, the Twin 10G SFP+ Thunderbolt 3 adapter is still large enough to support proper airflow inside the case—its design enables the adapter’s temperature-controlled, variable-speed fan to keep the adapter running cool and whisper-quiet at all times, making it suitable for use in noise-sensitive environments. Constructed of rugged and lightweight aluminum, the adapter’s outer shell securely protects the inner circuitry.
The Twin 10G SFP+ Thunderbolt 3 Edition adapter includes two Thunderbolt 3 (USB-C) ports; the first connects the adapter to your computer, while the second supports daisy-chaining of up to five additional Thunderbolt peripheral devices(4) to a single port on your computer. The Sonnet adapter includes 10Gbps USB 3.1 Gen 2 support, meaning you can connect a USB device(5) to the second port using the proper cable or adapter. The Twin 10G also provides full support for connecting two 4K displays @ 60Hz or one 5K display @ 60Hz(6). For connected devices requiring extra power, 15 watts is provided to connected bus-powered devices(7).
Sonnet includes a 0.5-meter Thunderbolt 3 cable to connect the Twin 10G SFP+ Thunderbolt 3 Edition to your computer, and a Sonnet ThunderLok 3 Thunderbolt connector retainer clip(8) to secure the cable to the adapter. Accidental cable disconnects can lead to data loss, but Sonnet’s ThunderLok 3 helps prevent them, securing the Thunderbolt cable to the adapter. ThunderLok 3 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 ThunderLok doesn’t attach to the connector, it remains on the cable and won’t get lost when not in use.
Connect computer to one port on the Twin 10G SFP+ Thunderbolt 3 Edition and daisy chain up to 5 additional Thunderbolt devices (plus two 4K monitors, one 5K display, or one USB 3.0 device)
