Tripp Lite's 10-meter( 33 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 4.88 m (16-ft.) Any length above 4.88 m (16-ft.) 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 39.92 m (131-ft.) by daisy chaining up to 4 of these active cables. The cable must be plugged directly into a USB port(either on the PC or a hub). Use a standard 1.83 m (6-ft.), 3.05 m (10-ft.), or 4.57 m (15-ft.) USB A-B cable to reach the desired distance. The U026-10M provides up to 150mA of power to the connected device. If your device requires more than 150mA 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 U026-10M.
