Ultra-fast Optical 10GbE Network Connectivity
With increasing demands for greater data transfer speeds and more bandwidth over shared networks, and with specialized applications such as 4K video editing using high-performance shared storage systems, it’s no wonder that 10 Gigabit Ethernet (10GbE) use has skyrocketed —this high-speed cabled networking standard offers ten times the performance of Gigabit Ethernet, the most common wired network connection included with most computers today. Sonnet offers a powerfully simple way to add dual-port 10GbE fiber optic connectivity to your Mac Pro® tower, Windows or Linux PC or server — Twin10G™ SFP28 PCIe Card.

Easy Network Connection

To enable easy connection to your 10GbE optical network, Twin10G SFP28 PCIe Card includes two short-range multi-mode fiber SFP28 transceivers (up to 300 meters).

The SFP28 transceivers are compatible with network switches equipped with SFP+ transceivers – and connect via the same LC/LC cables – ensuring the same optical 10GbE connectivity as an SFP+ card.
Long Range SFP28 Transceivers Available – Sonnet also offers long-range single-mode fiber modules that support 10Gb connections at up to 10 kilometers.

SMB Multichannel Support

Maximizes Throughput and Reliability with SMB Multichannel

Harness the full potential of Sever Message Block (SMB) Multichannel support with our Twin10G SFP28 PCIe Card. 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:
Checkmark Icon
Increased Throughput: By utilizing two network connections, the bandwidth of each port can be combined to deliver twice the data transfer rate.
Checkmark Icon
Increased Scalability: Easily expand your network’s capabilities. As your infrastructure grows, connect the additional Twin10G port to scale throughput without complex reconfiguration.
Checkmark Icon
Improved Fault Tolerance: Seamlessly keeps your computer connected in case a single cable is disconnected or one of the ports fails.
Checkmark Icon
Enhanced Load Balancing: Network traffic is dynamically distributed across available connections to prevent congestion and optimize performance under varying network demands.
Checkmark Icon
Reduced Latency: Minimizes delays by balancing traffic paths to enhance responsiveness in real-time operations.
