25 Gigabit Ethernet Thunderbolt Adapter with Two SFP28 Transceivers

compatible with Mac, Windows, and Linux

Incredible 25GbE Connectivity Over Thunderbolt

Many post-production shared storage teams and other bandwidth-heavy workflows have outgrown the capabilities of 10 Gigabit Ethernet (10GbE), which no longer delivers the speed and bandwidth needed for optimal performance. Upgrading to 25 Gigabit Ethernet (25GbE) is a smart move — it delivers significantly higher performance and often utilizes the same optical infrastructure as 10GbE. For these demanding environments, Sonnet’s Twin25G™ Thunderbolt Adapter offers a cost-effective and high-performance solution for adding ultra-fast 25GbE fiber optic network connectivity to Apple M series Macs, Intel Macs with Thunderbolt 3 ports, and Windows or Linux PCs with Thunderbolt 5 or Thunderbolt 4 ports.

Affordable 25GbE Networking

Make the Switch

Post-production workflows’ needs for speed and increased network bandwidth beyond the current 10Gb standard have increased more quickly than the availability of affordable higher speed network components. Recently, extremely affordable 25Gb Ethernet switches have become available, but connecting a computer with Thunderbolt ports, such as a Mac Studio, to a 25GbE infrastructure has remained expensive — until now. Twin25G Thunderbolt Adapter is the most cost-effective and powerfully simple solution for adding incredible 25GbE network connectivity to your computer without PCIe card slots.

Compact and Nearly Noiseless

Cool Running

Small enough to easily fit in most workspaces, Twin25G is still large enough to support proper airflow inside its case to enable the adapter’s temperature-controlled, variable-speed fan to keep the adapter always running cool and quiet.

Everything You Need to Connect Is Included

Simply connect the Twin25G Thunderbolt Adapter to your computer via the included 40Gbps Thunderbolt cable, install a driver, install the included SFP28 modules, connect the adapter to the network switch or directly to 25GbE-enabled storage, and then configure the adapter’s settings through the macOS Network control panel, Windows Device Manager, or Linux command line (or graphical utility).

Intelligent Operation

Efficient Performance

Twin25G attains high throughput performance with minimal host CPU load. The adapter’s smart controller has its own internal processing system with onboard memory to process TX/RX data while using few CPU resources. Once data appears in queues, TX checksums are computed on the fly as data is transmitted; RX checksums are quickly verified, and data is immediately passed directly to main memory. This independent controller action minimizes latency and avoids packet drops. The CPU is freed for other tasks.

Secure Connections for High Performance

Thunderbolt Cable and ThunderLok Included

Sonnet includes a Thunderbolt cable that supports Thunderbolt’s maximum bandwidth and is fully compatible with Thunderbolt 5, 4, and 3 computers. Sonnet also provides ThunderLok, a Thunderbolt connector cable lock, that prevents accidental cable disconnections.
