Gefen USB 2.0 Extender EXT-USB-400FON and Fiber Optic Cable 100ft Kit!

Extends any high speed USB 2.0 device up to 1640 feet (500 meters) from the USB source over multimode fiber optics cable

This new USB Extender supports all USB 2.0 devices, extending to 1640 feet (500 meters) away from the USB source. The receiver end is also a four USB 2.0 hub. 

By using fiber optic cables, the new Gefen USB 400FO extends a long distance from the location of a computer. It provides an EMI interference-free solution for USB extension work.

How It Works

The USB 400FO sender unit is connected to the source using the supplied USB short cable. The USB peripheral(s) are connected to the receiver unit at the extended side. Two LC-terminated fiber optic cables are used to link the sender to the receiver. 

Note:  This equipment is a new version of the existing part number, EXT-USB-400FO, and can provide outstanding extension facilities for anything that requires a USB connection over a distance, such as a USB camera or USB hard drive.
