Thunderbolt 3 10G Ethernet Adapter

System Requirements

Operating System:

  • Mac: macOS 10.13.6 or later
  • PC: Windows 10 or later


  • Mac or PC with a Thunderbolt 3 port

Compatible Connection Types:

  • 10GbE, 5GbE, 2.5GbE, 1GbE & 100MbE


Package Contents

  • OWC Thunderbolt 3 10G Ethernet Adapter
  • Thunderbolt 3 cable

Usage Notes

  • High quality Cat-6A Ethernet cable is recommended for distances up to 100m. At shorter distances, it’s possible to use cables of lower grade (e.g. Cat-6 for 10G or Cat-5e for 5G up to 55m).
  • To use this bus-powered device on older Thunderbolt and Thunderbolt 2 computers, it has to be connected to the second Thunderbolt 3 port on another self-powered Thunderbolt 3 device. If connected directly to the Thunderbolt 3 to Thunderbolt 2 adapter, bus-power is insufficient. A possible setup might look like this: Thunderbolt 2 Mac with macOS 10.13.6 or above > Thunderbolt 3 to Thunderbolt 2 adapter from Apple > self-powered Thunderbolt 3 device with two Thunderbolt 3 ports > Thunderbolt 3 10G adapter.
