Introduction
U3H442S is a high-performance four-port Universal Serial Bus (USB) 3.0 compliant Hub. U3H442S with F-One™ technology is a patented approach to attach multiple USB2 peripherals to a single SuperSpeed-only port. F-One™ mode implies a “Superspeed”-only upstream port.
U3H442S provides SuperSpeed-only USB connections on the upstream port and provides SuperSpeed (5Gbps) USB, High-Speed (480Mbps), Full-Speed (12Mbps), or Low-Speed (1.5Mbps) connections on the downstream ports.U3H442S will not work when the upstream port is connected to an electrical environment that only supports High-speed or Full-speed/Low-speed connections.
U3H442S is designed to be compliant with SuperSpeed USB electrical specifications, offering seamless interoperability between existing USB 3.0 hosts, USB 3.0 Active Optical Cable (AOC) and devices, ensuring a trouble-free plug-and-play experience. With an ultra-thin profile and long reach, the USB 3.0 AOC breaks the distance barrier and introduces a cost-effective and high-performance solution enabling existing devices to be used in new ways such as for industrial and security cameras, Industrial and Medical machine control and High-Definition surveillance.
