Connect four truly independent USB ports as far as 500 meters away (1640 feet) with this Gefen USB extender/hub over multimode fiber.
With a 17-foot USB signal limitation, USB can usually only be used for a limited spectrum of applications. With this extender hub, a whole new variety of solutions can be made using USB.

How To Use the USB Extender Hub Over Fiber
You will start by aquiring the fiber optic cables in the length of your choice. You will need two LC multimode fiber optic cables up to the length of 500 meters (1640 feet). Connect the included sender unit and receiver unit with the two cables and you've got a USB hub with 1640 feet distance capabilities.
The USB-400FO acts like a media converter, converting your USB signal into fiber and back again. The fiber allows for fast speeds over long distances with zero loss.
