OWC Thunderbolt 4 to 10Gb Ethernet Adapter

Thunderbolt 4 to 10 Gb Ethernet Adapter for high-speed network access – Black

The portable Ethernet supercharger

Enjoy warp-speed file transfers
Enhance your workflow with lightning-fast, bus-powered file transfers by connecting the OWC Thunderbolt 10G Ethernet Adapter to your Thunderbolt 3/4/5 or USB4 Mac or PC. Now you can access 10GBASE-T 10Gb Ethernet networks and other devices such as a NAS (Network Attached Storage) system to transfer large multimedia files at real-world speeds of over 900 MB/s. This adapter is also backwards compatible with other Ethernet standards, including 5GBASE-T, 2.5GBASE-T, 1000BASE-T and 100BASE-Tx.

Bottleneck-free collaboration during editing
With the OWC Thunderbolt 10G Ethernet Adapter, you can keep projects on schedule and within budget by providing multiple editing workstations with the bandwidth required for sharing and editing data-intensive creative content such as videos, animations and graphics. Advanced users can even connect multiple adapters to a single computer and utilise link aggregation to achieve even greater bandwidth (20–40 Gbps) when working with ultra-high-resolution footage or multi-camera projects.

Ideal for computers with limited Ethernet connectivity
The OWC Thunderbolt 10G Ethernet Adapter opens up a world of high-performance network connectivity for Thunderbolt 3/4/5 and USB4 laptops without built-in Ethernet connectivity, as well as for desktop computers that are limited by the old and slow standard 1-GbE port.

Drastic increase in performance and ROI for existing networks
Most wired local area networks installed over the last two decades use Cat 5e or Cat 6 copper cables. Unfortunately, these configurations are limited to a maximum speed of 1 Gb/s. Thanks to integrated 2.5 GBASE-T and 5 GBASE-T technology (formerly NBASE-T), the OWC Thunderbolt 10G Ethernet adapter can deliver speeds of up to 5 Gb/s over existing cabling, representing a performance increase of up to 500% and maximising infrastructure ROI.

Designed for optimal network and CPU performance
The OWC Thunderbolt 10G Ethernet Adapter achieves its lightning-fast transfer speeds and ensures your computer always operates at maximum performance, as it is equipped with advanced features such as flow control and 64-bit address support, TCP, UDP and IPv4 checksum offloading, as well as TSO, LRO and RSS stateless offloads.
