Gefen Fiber Optic USB Extender Boosts Distance up to 500m

5m is what we can pull from a normal USB cable. You can cascade up to several hubs, but you might get another 20m more. To really extend the distance up to 100 times more than the original USB distance, you have to go fiber optics. The Gefen USB 400FO is here to do just that. Licensing from Canada-based Extreme USB technology, Gefen's extender is able to boost signal for any USB devices for up to 500m (1650 ft.) from the location of your PC. That doesn't work on just one, but four USB devices, whether they are printers, keyboards, mice, hard drives or DVD burners.
