Add two SFP28 network interfaces to a USB Type-C host through a USB4 connection rated at 40 Gbps. The adapter presents two 25 Gigabit SFP28 ports for connection to compatible SFP28 network media. Its external Type-C host connection gives systems with a qualifying USB4 port a path to high-speed SFP28 networking without installing an internal expansion card. USB4 Type-C makes this adapter suitable where an internal PCIe card cannot be installed, including portable systems and compact edge equipment with a qualifying Type-C port. Thunderbolt 3, Thunderbolt 4, and Thunderbolt 5 compatibility broadens host connectivity across those port generations. The two SFP28 interfaces provide physical connections for two network links, while media selection remains at the SFP28 port. SY-TDB24107 concentrates on dual 25 Gigabit SFP28 connectivity rather than lower-speed copper Ethernet. Its USB4 40 Gbps host connection and two-port SFP28 layout distinguish it for deployments that need external high-speed network attachment from a Type-C-equipped host. Match the host's USB4 or Thunderbolt capability and the selected SFP28 media to the required network link before installation.
