The USB2.0 Active Repeater Cable is a 30 feet bus powered 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 so any length above 16 feet requires the use of an active cable such as this one. This cable has a signal booster built in so no signal will be degraded. These fully-rated universal serial bus cables provide transfer rates up to 480Mbps depending on USB version, and easily attach to any USB device. A/B cables are designed to connect from your USB port on Hub, PC or Mac to your USB device. Foil and braid shielding reduces EMI/RFI interference and twisted-pair construction helps reduce cross talk thus ensuring high-speed, error-free data transfer. Meets all the UL requirements for communication cabling, and is compatible with USB 1.0, 1.1, and 2.0.
