Thunderbolt 4 10G Ethernet Adapter (40Gbps)

The Thunderbolt 4 10G Ethernet Adapter delivers high-speed 10Gbps wired network connectivity to USB4 and Thunderbolt 3/4 host systems via a 40Gbps Type-C interface. It is ideal for makers, developers, and educators looking to expand networking performance on the LattePanda Sigma, compatible single-board computers, and workstations.

High-speed 40Gbps host interface

Powered by the JHL6340 Thunderbolt controller, this adapter delivers up to 40Gbps theoretical Type-C bus bandwidth. It connects seamlessly to compatible USB4 and Thunderbolt 3 or 4 desktop terminals, laptops, and embedded systems.

Native 10GBASE-T Ethernet port

Featuring an integrated AQC107 network controller, the standard RJ45 port provides transmission speeds up to 10Gbps when paired with CAT6 or higher cabling. It also supports adaptive backwards compatibility with Gigabit and 100Mbps networks.

Active cooling for heavy loads

The all-metal enclosure combines multi-directional ventilation slots with an internal cooling fan to actively dissipate heat. This thermal design ensures reliable, sustained link operation during continuous high-throughput data transfers.

Onboard RJ45 status indicators

Integrated LED indicators on the Ethernet port provide instant visual feedback during operation and troubleshooting. A yellow LED indicates network link status while a blue LED confirms real-time data activity.

Broad operating system support

Measuring 106x50x25mm, the compact unit supports Windows 10 and 11, Linux, and macOS platforms. It comes complete with a 30cm Thunderbolt data cable for immediate deployment.
