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.
The Twin25G Thunderbolt Adapter is a pre-configured bundle of Sonnet Twin25G PCIe Card with Sonnet Echo Express SEL Thunderbolt Expansion Chassis.
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.
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, Including Apple M series Macs
Supports Apple M series and 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.
