The cable is designed for USB1.0, 1.1 and 2.0 versions. The noise filter helps prevent EMI & RFI which may affect transmission speeds. This cable supports plug & play connections for devices such as external hard drives, modems, printers, scanners, VOIP devices & other USB peripherals. We highly recommend this cable for all critical and high-speed applications because it comes with a ferrite core noise filter which is very important for a sustained, error-free data flow.
