Product Overview

This product expands two independent PCIe x4 slots through a single USB4 interface. By installing two PCIe-to-4-port Gigabit Ethernet adapters (featuring Realtek 8111H chips), the docking station transforms into an 8-port Gigabit Ethernet expansion device. It supports scenarios such as multi-port network access, network testing, server virtualization, software-defined routing, and network storage, delivering high-speed, stable network expansion capabilities.

Features

• Plug-and-Play: USB4 technology enables operation without driver installation on mainstream operating systems.

• High Performance: Single device delivers 40Gbps bandwidth.

• Dual-Device Concurrency: Supports simultaneous use of two PCIe devices, sharing the USB4 40Gbps bandwidth limit.

• Requires external power supply and 40Gbps cable.

• Total speed shared across 40Gbps bandwidth when two devices operate simultaneously.
