TWIN25G-TB Twin25G Thunderbolt Dual Port 25Gb Ethernet Adapter (SFP28s included)



Blazing Fast 25GbE Networking

25 Gigabit Ethernet Thunderbolt Adapter with Two SFP28 Transceivers
for computers with Thunderbolt™ 4 or Thunderbolt 3 ports

Incredible 25GbE Connectivity Over Thunderbolt

Many post-production shared storage workgroups and other bandwidth-intensive workflows have reached a point where 10Gb Ethernet (10GbE) does not provide enough bandwidth and speed for optimum performance. Stepping up to 25Gb Ethernet (25GbE) makes a lot of sense — it offers greater performance and often works with the same optical network infrastructure as 10GbE. For these workgroups, there is now a cost-effective 25GbE interface for your Mac®, Windows®, or Linux® computer with Thunderbolt™ 4 or Thunderbolt 3 ports — Sonnet’s Twin25G™, an affordable yet powerful solution for adding incredibly-fast fiber optic 25GbE network connectivity.

Affordable 25GbE Networking

Make the Switch

Postproduction 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. Sonnet’s 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, the Twin25G adapter 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 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

The Twin25G adapter 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.
All the Right Connections

40Gbps Thunderbolt Cable and ThunderLok 3 Included

Sonnet includes a Thunderbolt cable that supports Thunderbolt’s full 40Gbps bandwidth, and is fully compatible with Thunderbolt 4 and Thunderbolt 3 computers. Sonnet also provides a ThunderLok™ 3 Thunderbolt connector retainer clip that prevents accidental cable disconnections — just slide it over one end of the cable, and then plug in the connector and secure it to the chassis by turning a thumbscrew. Because of its unique design, ThunderLok remains on the cable so it won’t get lost when not in use.
