Sonnet Twin10G SFP28 Thunderbolt Adapter – Dual 10GbE Optical Ports with Transceivers

If you’re looking to connect your Mac, Windows, or Linux workstation to a high-speed 10GbE fiber network, the Sonnet Twin10G SFP28 Thunderbolt Adapter is the compact, high-performance solution you've been waiting for. Whether you're editing 4K video, transferring massive datasets, or managing large storage volumes, this dual-port adapter delivers the power and flexibility you need.

Designed as a bundled solution, it includes the Sonnet Twin10G SFP28 PCIe Card pre-installed in the Echo Express SEL Thunderbolt Expansion chassis, giving you a plug-and-play Thunderbolt 3, 4, or 5 compatible optical network interface.

Each unit comes with two SFP28 short-range transceivers pre-installed, offering reliable connectivity up to 300 meters via multi-mode fiber. Need more range? You can opt for Sonnet's long-range modules, which stretch up to 10km.

Beyond blazing speed, this adapter also supports SMB Multichannel, allowing both ports to work together for enhanced throughput, better scalability, and built-in failover. The result? Fewer bottlenecks and more stability across your network operations.

Despite its performance, the Twin10G SFP28 is whisper-quiet. A temperature-controlled fan and rugged aluminum housing ensure silent operation in noise-sensitive environments like edit suites and production studios.

Setup is as easy as it gets: plug it in, install the driver, and you’re connected to your optical network. It's also designed for daisy-chaining other Thunderbolt devices, powering USB peripherals, or even running an 8K display — all from a single port.
