Cables Unlimited's USB 2.0 A to B Active Device Cable is a bus-powered USB cable that can be used to increase the length of a device cable without the worry of signal loss and potential performance problems. The specification for USB states that the maximum length of a USB cable is 5 meters (16 feet). As a result, you cannot extend the distance of your USB device more than 16 feet without using a USB "active" cable. This cable contains active electronics which boost the USB signal for maximum reliability and performance over extended distances.
