Blazing 10GbE Optical Networking
Twin10G SFP28 Thunderbolt Adapter
Dual-port SFP28 10 Gigabit Ethernet Thunderbolt Adapter for Mac, Windows, and Linux Computers with Thunderbolt Ports
Add Blazing-fast Optical 10GbE Connectivity Over Thunderbolt
Are you looking for the most economical dual-port approach to connecting to a high-speed 10 Gigabit Ethernet (10GbE) fiber network using the Thunderbolt™ port on your Mac®, Windows®, or Linux® computer? You’ll need the Sonnet adapter. Sonnet Twin10G™ SFP28 Thunderbolt Adapter is the powerfully simple solution for adding blazing-fast dual-port 10GbE optical network connectivity to your computer.
Twin10G SFP28 Thunderbolt Adapter is a pre-configured bundle of Sonnet Twin10G SFP28 PCIe Card with Sonnet Echo Express SEL Thunderbolt Expansion System.
Includes Two SFP28 Transceivers
To enable easy connection to your 10GbE optical network, Twin10G SFP28 includes two short-range multi-mode fibre SFP28 transceivers (up to 300 meters).
Long Range SFP28 Transceivers Available
Sonnet also offers long-range single-mode fiber modules that supports 10Gb connections at up to 10 kilometers.
More Bandwidth
Each Twin10G port supports ten times the performance of Gigabit Ethernet with even more bandwidth when combining ports.
Maximizes Throughput and Reliability with SMB Multichannel
Harness the full potential of Sever Message Block (SMB) Multichannel support with our Twin10G SFP28 Thunderbolt Adapter. When both ports are connected to your SMB server, you can combine their bandwidth to achieve significantly higher data transfer speeds, and more. SMB Multichannel support brings several key benefits:
Increased Throughput – By utilizing two network connections, the bandwidth of each port can be combined to deliver twice the data transfer rate.
Increased Scalability – Easily expand your network’s capabilities. As your infrastructure grows, connect the additional Twin10G port to scale throughput without complex reconfiguration.
Improved Fault Tolerance – Seamlessly keeps your computer connected in case a single cable is disconnected or one of the ports fails.
Enhanced Load Balancing – Network traffic is dynamically distributed across available connections to prevent congestion and optimize performance under varying network demands.
Reduced Latency – Minimizes delays by balancing traffic paths to enhance responsiveness in real-time operations.
Suitable for Use in Noise-sensitive Environments
Small enough to easily fit in most workspaces, Twin10G SFP28 Thunderbolt Adapter is still large enough to support proper airflow inside the case — its design enables the adapter’s temperature-controlled, variable-speed fan to keep the adapter running cool and whisper-quiet at all times, making it suitable for use in in almost any workspace. Constructed of rugged and lightweight aluminum, the adapter’s outer shell securely protects the inner circuitry.
Intelligent Operation. Efficient Performance.
Twin10G SFP28 Thunderbolt 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 –
Thunderbolt Cable and ThunderLok Included
Sonnet includes a Thunderbolt cable that supports Thunderbolt’s maximum bandwidth and is fully compatible with Thunderbolt 3, 4 or 5 computers. Sonnet also provides a ThunderLok™ Thunderbolt connector retainer clip that prevents accidental cable disconnections.
Thunderbolt Interface
Twin10G SFP28 Thunderbolt Adapter features a high-speed Thunderbolt interface that delivers the PCIe bandwidth to support two 10Gb ports at full speed.
Thunderbolt Port to Connect Additional Devices – One port is reserved for the connection to your Thunderbolt computer; the second port enables expansion of additional Thunderbolt peripheral devices in a daisy chain.
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 using the proper cable or adapter.
Provides 15W of Power – For bus-powered peripherals requiring extra power, 15 watts is provided to bus-powered devices.
Supports Connecting Up to One 8K Display – Maximize the utilization of one computer Thunderbolt port, connecting the largest display supported by your computer.
