OWC Thunderbolt 4 to 10Gb Ethernet adapter

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

The portable Ethernet supercharger

Utilise warp speed for file transfers
Add lightning-fast, bus-powered file transfers to your workflow 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 900MB/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 processing
With the OWC Thunderbolt 10G Ethernet Adapter, you can keep projects on schedule and on budget by providing multiple editing workstations with the bandwidth needed to share and edit data-intensive creative content such as video, animation and graphics. Advanced users can even connect multiple adapters to a single machine and use link aggregation to achieve even greater bandwidth (20-40 Gbps) when working with ultra-high-definition 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 desktop computers limited by the old and slow standard 1GbE port.

Drastically increase the performance and ROI of existing networks
Most wired local area networks installed over the last two decades use Cat 5e or Cat 6 copper cabling. Unfortunately, these configurations are limited to a maximum speed of 1 Gb/s. Thanks to the 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, which corresponds to a performance increase of up to 500 % and a maximum ROI for the infrastructure.

Designed for optimal network and CPU performance
The OWC Thunderbolt 10G Ethernet adapter achieves its lightning-fast transmission speed and keeps your computer operating at peak performance with advanced features such as flow control and 64-bit address support, TCP, UDP and IPv4 checksum offloading, and TSO, LRO and RSS stateless offloads.
