The D-Link DUB-C5AB is a 15 ft Hi-Speed USB 2.0 certified type 'A' to type 'B' cable. USB 2.0 extends the speed of the peripheral-to-PC connection from 12 Mbps on USB 1.1 to up to 480 Mbps -- 40 times faster than USB 1.1 when connected to another USB 2.0 device. The higher bandwidth supports such applications as digital image creation and web publishing, where multiple hi-speed peripherals run simultaneously. As Hi-Speed USB 2.0 devices are released to the market, quality and compatibility with other USB devices is extremely important. The D-Link DUB-C5AB is USB-IF certified to ensure that your USB devices will work and operate at the fastest speed possible.
