SONNET Twin25G – 25 Gigabit Ethernet Thunderbolt Adapter
(Includes Two SFP28 Transceivers)
The SONNET Twin25G delivers incredible Dual 25GbE Connectivity Over Thunderbolt 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.
Twin25G-TB Key Features
- Adds High-performance 25GbE Connectivity
Simply powerful way to add dual optical 25GbE connections to any computer with Thunderbolt 4 or Thunderbolt 3 ports.
- SFP28 Transceivers Included
High-performance adapter includes two 25GBASE SFP28 transceivers.
- Backward Compatible
Adapter also supports 10GbE — enables you to integrate with 10GbE infrastructure now and upgrade your switch or shared storage system to 25GbE later.
- Mac Compatible
Supports Macs with Thunderbolt 4, Thunderbolt/USB4, and Thunderbolt 3 ports.
- Windows Compatible
Supports Windows computers with Thunderbolt 4 and Thunderbolt 3 ports.
- Linux Compatible
Supports Linux computers with Thunderbolt 4 and Thunderbolt 3 ports.
- 40Gbps Thunderbolt Device
40Gbps Thunderbolt supports the full bandwidth of one 25GbE port.
- Two Thunderbolt Ports
One port connects to computer; second port provides 15W for a Thunderbolt or USB 3 device; or to connect up to an 8K display.
- Compact. Nearly Noiseless.
Adapter is small enough to comfortably fit on any desktop, and quiet enough for use in noise-sensitive environments. You’ll hardly notice it’s there.
Free Lifetime Tech Support
Sonnet was established in Irvine, California in 1986. Since then, we’ve pioneered and brought to market many innovative and award-winning products that enhance the performance and connectivity of Mac, Windows, and other industry-standard computers. Many of our employees have been with the company for more than 20 years. We have a wealth of knowledge about our current and past products. Should you ever need technical support on one of our products, contact us; we’ll be around to help you.
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
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.
- Dual 40Gbps Thunderbolt Ports
One port is reserved for the connection to your Thunderbolt 4 or Thunderbolt 3 computer; the second port provides 15W for a Thunderbolt or USB 3 device; or to connect up to an 8K display.
- 10Gbps USB 3.2 Gen 2 Support
10Gbps USB 3.2 Gen 2 support allows you to connect a USB device to the second Thunderbolt port.
- Provides 15W of Power
For peripherals requiring power, 15 watts is provided to bus-powered devices.
- Supports Connecting One Up to 8K Display
Maximize the utilization of one computer Thunderbolt port, connecting the largest display supported by your computer.
