Add Blazing-Fast Dual 10GbE Fiber Optic Networking Over Thunderbolt
For creative professionals and IT power users demanding elite network performance, the Sonnet Twin10G SFP28 Thunderbolt Adapter is the ultimate solution for adding dual-port 10GbE fiber optic connectivity to your Mac, Windows, or Linux computer. This adapter provides a powerful and cost-effective way to connect to high-speed network infrastructure and storage, completely eliminating data transfer bottlenecks. Whether you're editing multi-stream 8K video, managing massive databases, or executing high-volume backups, the Twin10G SFP28 delivers the extraordinary speed and steadfast reliability required to dramatically accelerate your professional workflows.
At its core, this adapter unleashes the full potential of your network with support for SMB (Server Message Block) Multichannel. By connecting both 10GbE ports to an SMB-enabled switch or server, you can aggregate their bandwidth to achieve staggering throughput—up to twice the speed of a single connection. This advanced feature also provides critical fault tolerance; if one cable is disconnected or a port fails, your connection remains active through the second link, ensuring uninterrupted access to your data. Intelligent load balancing also works to dynamically distribute network traffic, preventing congestion and minimizing latency for superior responsiveness in real-time applications.
Engineered for demanding professional environments, the Twin10G SFP28 is housed in a compact, rugged aluminum chassis that is both durable and exceptionally quiet. Its temperature-controlled, variable-speed fan ensures the high-performance NVIDIA Mellanox controller stays cool under maximum load while remaining whisper-quiet, making it a perfect fit for noise-sensitive studios and offices. This bundle is a complete, ready-to-use solution right out of the box, shipping with two short-range SFP28 transceivers, a 0.7m Thunderbolt cable, and Sonnet's unique ThunderLok™ 3 retainer clip to secure your connection. Simply connect it to your computer's Thunderbolt port to instantly supercharge your networking capabilities.
