Thunderbolt 3 10GbE adapter for professionals

The StarTech TB310G2 adds a multi-gigabit RJ45 port to Thunderbolt 3 or 4 computers. It supports 1G, 2.5G, 5G, and 10G network speeds for demanding workflows. The Marvell AQC107S chipset enables plug-and-play operation on Windows and macOS. This bus-powered adapter suits IT pros and mobile users needing fast wired connectivity.

Certified cable and passive cooling

A detachable 70cm Thunderbolt 3 cable is included for reliable link performance. The all-aluminium chassis doubles as a heatsink for silent, fanless operation. Status LEDs show link and activity at a glance. Features include Wake-on-LAN, autonegotiation, and NBASE-T support for broad switch compatibility.

Handles 10GbE with headroom to 1G

Comfortably drives 10GbE storage, server admin, and high-bitrate streaming tasks. Multi-gig support down to 100Mb/s ensures legacy network integration. The compact 108.5x75x29.1mm footprint fits tight workspaces. Buyers needing fibre SFP+ ports or a second RJ45 connector should look elsewhere.

Questions about this item

Will the Marvell AQC107S chipset or the Thunderbolt 3 cable need replacement after heavy use?

The adapter has no moving parts and uses passive cooling, so the chipset itself does not wear out. The included 27.5 in certified Thunderbolt 3 cable is detachable and can be swapped if the connector or cable jacket becomes damaged.

What limits sustained 10 GbE throughput on this adapter?

Sustained speed is capped by the 10 GbE RJ45 port and the Marvell AQC107S controller, which negotiate down to 5 GbE, 2.5 GbE, 1 GbE or 100 MbE depending on the connected switch and cabling.

How much heat or noise does the all-aluminium chassis produce during all-day operation?

The 4.27 x 2.9 x 1.14 in aluminium enclosure acts as a heatsink for silent, fanless cooling. Bus power from the Thunderbolt 3 port keeps power draw low, so the unit stays quiet and only warm to the touch under continuous load.
