Sonnet TWIN25G-T5

Twin25G Thunderbolt 5 Ethernet Adapter

Incredible Dual-port 25GbE Connectivity Over Thunderbolt
If your post-production or bandwidth-intensive workflows have pushed past the limits of 10GbE, the jump to 25GbE offers the speed you’ve been missing — often using the same optical cabling already in place. Sonnet’s Twin25G® T5 Thunderbolt™ 5 Adapter offers a cost-effective, high-performance way to add ultra-fast 25GbE fiber connectivity to Apple M series Macs, Intel Macs with Thunderbolt 3, and Windows or Linux computers with Thunderbolt 5, 4, or USB4 ports.

Affordable 25GbE Networking - Make the Switch
As post-production workflows outgrow 10GbE, new low-cost 25GbE switches make upgrading easier than ever — yet connecting a computer with Thunderbolt or USB4 ports to a 25GbE network has remained expensive. The Twin25G T5 Thunderbolt 5 Adapter changes that, delivering fast, affordable 25GbE connectivity to systems without PCIe slots.

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.

80 Gbps Thunderbolt Device
Supports the full bandwidth of two 25GbE ports when connected to a Thunderbolt 5 computer port; one port’s full bandwidth supported with Thunderbolt 4, 3, and USB4 computers.

Two Thunderbolt 5 Ports
One port connects to computer; second port provides 15W for a Thunderbolt or USB device; or to connect 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.

Compact and Nearly Noiseless - Cool Running
Small enough to easily fit in most workspaces, Twin25G T5 is 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.

Easy Connection - Includes Thunderbolt 5 Cable and SFP28 Modules
Simply install a driver, connect the Twin25G T5 Thunderbolt 5 Adapter to your computer via the included 120 Gbps Thunderbolt 5 cable, 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; your computer’s CPU is freed for other tasks.

Secure Connections for High Performance - Thunderbolt 5 Cable and ThunderLok Included
Sonnet includes a Thunderbolt cable that supports Thunderbolt’s maximum bandwidth and is fully compatible with Thunderbolt 5, 4, 3, and USB4 computers. Sonnet also provides ThunderLok, a Thunderbolt connector cable lock, that prevents accidental cable disconnections.

Twin25G T5 is built with the features and quality you expect from a high-performance Sonnet Ethernet adapter, plus the Thunderbolt 5 interface you need for maximum performance. With 80 Gbps of bi-directional data speed — twice as fast as Thunderbolt 4 — and up to 120 Gbps for higher display bandwidth, you'll revolutionize your productivity.

More Than Just the Fastest External Interface Available
Twin25G T5 features an ultra-high speed Thunderbolt 5 interface that delivers the PCIe bandwidth needed to support both Ethernet ports at maximum performance. While one Thunderbolt port is reserved for connecting your computer, the secondary port enables connection of additional Thunderbolt or USB peripheral devices
