Sonnet Twin10G Thunderbolt 3 Edition – Product Overview
The Sonnet Twin10G Thunderbolt 3 Edition brings dual-port 10GBASE-T networking to computers with Thunderbolt connectivity, providing the PCIe bandwidth required to drive two 10Gb Ethernet connections in a compact external adapter.
Dual 10GBASE-T RJ45 Ports
Two RJ45 ports connect directly to copper 10GbE switches, storage and infrastructure. Sonnet specifies up to 100 metres over Cat 6A cabling or up to 55 metres over Cat 6 for 10GBASE-T operation.
Thunderbolt Connectivity
One Thunderbolt port connects to the host computer while the second supports daisy-chaining compatible Thunderbolt peripherals. The adapter's Thunderbolt 3 architecture provides the PCIe bandwidth needed for high-performance dual-port networking.
Professional Networking Features
The Intel X540-based design supports features including flow control, checksum offload, transparent failover and jumbo frames. Windows and Linux systems can also use link aggregation where supported by the operating system and network configuration.
Compact, Quiet Design
A rugged aluminium enclosure protects the internal hardware, while a temperature-controlled variable-speed fan manages cooling with low acoustic output for desktop and production environments.
