Thunderbolt 3 10GbE SFP+ adapter

The Solo10G SFP+ connects a Mac or Windows computer with Thunderbolt 3 ports to 10GbE infrastructure using a short-range SFP+ transceiver. It targets creators and workgroups handling large 4K-and-above files who need fast fibre connectivity without a dedicated NIC slot. The aluminium enclosure is pocket-sized and fanless for silent operation.

Bus-powered plug-and-play setup

Powered entirely through the Thunderbolt 3 link, the adapter requires no external supply and adds 10GbE via the macOS Network pane or Windows Device Manager. The 40 Gbps host interface and included 10GBASE-SR module support LC multi-mode fibre runs up to 300 meters; cable is sold separately. Hardware-encrypted firmware prevents unauthorised modification.

Check Thunderbolt 3 port and fibre patch cables

Verify the host has a Thunderbolt 3 port able to deliver bus power for the adapter. Confirm the network switch or storage array accepts 10GBASE-SR SFP+ modules and that LC multi-mode patch cables of the required length are available. The adapter draws power from the port, so daisy-chain position and total bus load should be reviewed.
