U31H201 is a high-performance two port Universal Serial Bus (USB) 3.1 Gen 2 compliant Hub (Boost the USB Bus-Power Voltage), extending your USB 3.1 signals an additional length (Gen1: 4~7m, Gen 2: 2~3.5m).

One upstream port and two downstream ports support not just SuperSpeed Plus transfer, but are also backwards compatible with previous USB specifications and offer support for SuperSpeed(5Gbps), Hi-Speed (480Mbps), Full-Speed (12Mbps), and Low-Speed (1.5Mbps) traffic.

U31H201 allows for a maximum data transfer rate of up to 10Gbps, or twenty times the throughput available to USB 2.0 based devices. Other enhancements provide for improved interaction between device and host controller, including important advancements in power management.

Note: The greater the number of hubs or the length of a cable, the higher the electricity consumption.
This results in a decrease in electricity supplied to the terminal device.
