USB Gen 2x2 20G or Gen 2x1 10G adapter cable to 10Gigabit Ethernet 10G, 5G, 2.5G, 1G RJ45 network with Realtek RTL8159 controllers

Instantly transforms a USB-C port into a high-speed 10GBASE-T network interface. Based on the Realtek RTL8159 chipset, it delivers near-10G performance without requiring a PCIe slot.

Compatibility:

Natively supported by Windows 10/11, Linux (kernel 5.8 or higher), macOS (driver required)

Compatible with TrueNAS, UnRAID, Proxmox, VMware ESXi (via USB passthrough).

Connect to a USB Type-C port (USB 3.2 Gen2). Compatible with USB 3.2 Gen 2x1 (10G), but use on USB 3.2 Gen2x2 (20 Gbps) is recommended for maximum performance.

Use on an RJ45 network with Cat6a or higher cabling for 10G connectivity.
