What this adapter adds

The Qnap Thunderbolt 3 10GbE SFP+ Adapter adds a single 10GbE SFP+ port to a Mac or Windows computer through Thunderbolt 3. It draws power from the bus so no external supply is needed. Supported link rates reach 10 Gbps, 5 Gbps, 2.5 Gbps, 1 Gbps and 100 Mbps. A Thunderbolt 3 cable is included in the box.

What to verify on your system

Confirm your computer has a Thunderbolt 3 port that supports external networking devices. Ensure the operating system recognises Thunderbolt networking adapters without extra drivers. You must supply a compatible SFP+ module or direct-attach cable for the network link. The adapter measures 1.08 by 2.20 by 4.41 inches, so check desk space.

Who this suits and who it does not

Suits creators and IT professionals who need portable 10GbE access over Thunderbolt 3 for large file transfers or NAS expansion. Not for buyers who want more than one network port from a single adapter. Not for systems that lack Thunderbolt 3 or cannot pass networking traffic through the Thunderbolt controller.
