Description

StarTech TB310G2 Thunderbolt 3 to 10GbE Ethernet Adapter

Overview

The StarTech TB310G2 adapter provides a direct path to 10 Gigabit Ethernet speeds from a Thunderbolt 3 port. This is critical for high-bandwidth applications like large file transfers, direct-attached storage access, and high-resolution video streaming where standard Gigabit Ethernet becomes a bottleneck. Its compact, bus-powered design makes it suitable for mobile workstations or desktop setups where adding a full 10GbE NIC is not feasible. The adapter uses the Marvell AQC107S chipset, known for its reliable performance in demanding network environments.

Compatibility

This adapter is compatible with systems featuring a Thunderbolt 3 USB-C port. It supports Windows 10 and 11, as well as macOS versions 10.15 through 26.x. It connects to networks operating at 10 Gbps, 5 Gbps, 2.5 Gbps, 1 Gbps, and 100 Mbps, adhering to IEEE 802.3an, 802.3bz, 802.3ab, and 802.3u standards. The integrated RJ-45 port accepts standard Ethernet cables.

Installation Notes

The adapter is bus-powered, drawing power directly from the Thunderbolt 3 port, eliminating the need for an external power supply. It supports Jumbo Frames up to 16K, which can improve throughput for large data packets by reducing processing overhead on compatible network infrastructure. Operating temperature range is 10°C to 55°C (50°F to 131°F), with identical storage temperature limits. Humidity tolerance is 20% to 80% RH.
