10Gb Ethernet Adapter for Thunderbolt and USB4

This adapter adds a 10Gbps RJ45 port to hosts with Thunderbolt 3, Thunderbolt 4 or USB4 interfaces. It is intended for professionals moving large media files, editing 4K video or running high-bandwidth workloads that exceed standard gigabit links. Windows systems require a driver install while macOS and Linux operate plug-and-play.

Speeds of 10, 5, 2.5, 1Gbps

The link negotiates down through 5Gbps, 2.5Gbps, 1Gbps and 100Mbps Base-T so it works with existing switches and routers. Full 10Gbps throughput is only reached when both the upstream network and the downstream device also support 10Gbps; otherwise the connection settles at the highest common rate.

Bundled 40Gbps cable and 24/7 technical assistance

A certified 40Gbps cable is included so the adapter can be connected at full host bandwidth without a separate purchase. Round-the-clock technical assistance is also provided to help with driver setup on Windows or any configuration questions that arise during deployment.

Questions about this item

Will the 10 Gbps adapter work with my older 1 Gbps switch and cabling?

The adapter auto-negotiates down to 1 Gbps, 100 Mb/s, 2.5 Gbps or 5 Gbps so it will link with existing switches and Cat 5e or better cables, but full 10 Gbps throughput needs a 10 Gbps switch and Cat 6a or higher wiring end-to-end.

How can I confirm the adapter is running at 10 Gbps after I plug it in?

On macOS or Linux the link speed appears immediately in the network settings; on Windows install the supplied driver first, then check the adapter properties or Task Manager performance tab for a 10 Gbps link indication.

Does the package include everything I need to connect to a Thunderbolt 3 port, or must I buy a cable separately?

The box contains the adapter, a 40 Gbps Thunderbolt cable and a user manual, so no extra cable purchase is required for Thunderbolt 3 or 4 and USB4 hosts.
