Tripp Lite's 16-ft. USB 2.0 active extension cable is a bus powered extension cable that can be used to increase the length of a device cable without the worry of signal loss and potential performance problems. USB limits a cable's length to 16ft. Any length above 16 feet requires the use of an active cable such as this one. This cable has a signal booster built in. The overall cable length can be extended up to 80ft by daisy chaining up to 5 of these active cables. The U026-016 provides up to 250mA of power to the connected device. If your device requires more than 250mA of power, it will either need to have its own power supply; or, to be plugged into a powered USB 2.0 hub (such as U222-004-R) that is connected to the U026-016. Use a standard 6' 10' or 15' USB cable to reach the desired distance.
