Personal computer accessory designed to deliver high-speed wired networking over Thunderbolt connections. Ideal for editors, streamers and AV professionals who need steady transfers and low latency. Is the OWC Thunderbolt 4 Ethernet Adapter the right upgrade for a Thunderbolt-equipped workstation?
⚡ At a Glance
- • Transfer Speed: High throughput suited to large file transfers and live streaming
- • Best for: Video editors, streamers, and professionals requiring stable wired networking
- • Not ideal for: Systems without Thunderbolt ports or users who rely solely on Wi-Fi
Thunderbolt 4 connection provides a direct path to 10Gb/s Ethernet through an RJ45 port. Auto-negotiation supports multiple Ethernet standards for broad compatibility.
Blazing-fast transfers - thanks to Thunderbolt 4 and 10Gb/s Ethernet
Thunderbolt 4 host ports carry sufficient PCIe bandwidth to support full 10Gb/s Base-T Ethernet over the RJ45 interface; real-world testing reports sustained transfers around 900MB/s for large files.
Faster copies of multi-gigabyte media and large backups reduce idle time during editing and deliver smoother collaboration on shared projects.
Reliable long-distance connections - with Cat6a/Cat6/Cat5e compatibility and auto-negotiation
Cat6a cabling supports 10G up to 100 metres while Cat6 and Cat5e enable lower multi-gig speeds; auto-negotiation selects the highest common speed between endpoints automatically.
Network runs across offices or studio racks maintain stable link speeds without manual configuration, simplifying installation in larger setups.
Studio and remote-ready networking - with Wake-on-LAN and AVB readiness
Wake-on-LAN allows remote wake and management of connected hosts, while AVB readiness supports time-synchronised audio/video streams required for professional AV workflows.
Headless machines can be accessed remotely for maintenance, and low-latency, sync-critical audio/video work benefits from consistent timing and reduced jitter.
