Sonnet Twin 10G Thunderbolt 3 Edition



Product Details

Blazing-Fast 10GBASE-T Connectivity Over Thunderbolt 3 for Mac and Windows

The Twin 10G Thunderbolt 3 Edition adapter is compact enough to easily fit in most workspaces, yet 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 aluminium, the adapter’s outer shell securely protects the inner circuitry.

Specifications and appearance are given as guidelines and may change without notice.

        Technical Notes

        1. Windows computers require the latest firmware (BIOS) and Thunderbolt drivers to support this product. Check with your computer manufacturer for update information.
        2. Full performance requires the use of the included Thunderbolt 3 (40Gbps) cable, or other Thunderbolt 3 (40Gbps) cables; look for the Thunderbolt icon AND the number 3 on the connector housings to identify these cables.
        3. Switch/router must support link aggregation (teaming), and ports must be configured for link aggregation. Windows 10 teaming requires Creator's update, version 1703 or greater.
        4. Second Thunderbolt 3 port supports Thunderbolt and Thunderbolt 2 peripheral devices on Macs used with the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter, sold separately.
        5. Second Thunderbolt 3 port supports USB 3.1 Gen 1 (5Gb) or Gen 2 (10Gb) devices when connected with proper cable or adapter (sold separately).
        6. One 4K monitor directly supported. Two 4K monitors requires either a 4K monitor with multi-stream transport support (DP out), or a Thunderbolt 3 to Dual DisplayPort adapter. 5K monitor requires a Thunderbolt 3 to Dual DisplayPort adapter. All Thunderbolt 3 Macs support two 4K monitors. Most Thunderbolt PCs support two 4K monitors.
        7. Feature to be added in a future firmware release to support Windows.
        8. ThunderLok 3 compatible with Sonnet 0.5 meter Thunderbolt 3 cables, but not with Sonnet 1-meter Thunderbolt 3 cables.
