The Sonnet Twin 10G Thunderbolt 3 to Dual-Port 10 Gigabit Ethernet Adapter provides two 10GbE ports for your Thunderbolt 3 system. The Twin 10G features two Thunderbolt 3 ports, so you can daisy-chain up to 6 Thunderbolt devices to a single system. To provide a reliable and fast networking connection, the 10GbE ports are outfitted with failover and link-aggregation support. With an onboard Intel X550 10GbE controller, the Twin 10G assists your system's processor with flow controls as well as TCP, UDP, and IPv4 checksum processes, freeing up the CPU to work on other tasks. For cooling the internal components, it comes equipped with a variable-speed fan. Moreover, Sonnet includes a 1.6' Thunderbolt cable along with a ThunderLok 3, which secures the cable to the chassis.
