Dual-port 10GBASE-T 10 Gigabit Ethernet Thunderbolt Adapter

Blazing-fast 10GBASE-T (Copper) Connectivity Over Thunderbolt
Rising demand for faster data transfer speeds and increased bandwidth on high-performance shared storage networks has fueled the rapid growth of 10 Gigabit Ethernet (10GbE) adoption. However, most computers still lack built-in support for this ultra-fast connectivity. Twin10G™ Thunderbolt Adapter offers a powerful yet straightforward and cost-effective way to add blazing-fast, dual-port 10GBASE-T 10GbE network connectivity to your system. It works seamlessly with Apple M series Macs, Intel Macs with Thunderbolt 3 ports, and Windows or Linux PCs equipped with Thunderbolt 5 or Thunderbolt 4 ports.
Connect to 10GbE Infrastructure
Twin10G adapter is equipped with two RJ45 ports, enabling it to connect to 10GbE infrastructure via inexpensive Cat 6 or Cat 6A copper cabling at distances up to 55 or 100 meters, respectively.
Compact and Nearly Noiseless

Simplified Setup
How simple? Just connect Twin10G adapter to your computer via the included 40Gbps Thunderbolt cable, download and install a driver, connect the adapter to the network switch or directly to 10GbE-enabled storage via Cat 6 or Cat 6A cables, and configure the adapter’s settings through the macOS Network control panel, Windows Device Manager, or Linux command line (or graphical utility).
Intelligent Operation
Twin10G adapter attains its high throughput performance and low host-CPU utilization through functions such as flow control, 64-bit address support for systems using more than 4GB of physical memory; and stateless offloads such as TCP, UDP and IPv4 checksum offloading. These processes enable your computer to perform better while large files transfers or high I/O operations take place. This Sonnet adapter’s dual 10GbE connections support transparent failover to keep your computer connected in case a single cable is disconnected or one of the ports fails. Windows and Linux also support link aggregation (teaming) for increased throughput!
