Perfect Connection. The maximum length of any normal USB 2.0 cables is 5 meters. Extending them any longer will lead to signal loss and problems with data transfer. The solution is to use this active USB extension cable. This will allow you to extend USB cables up to 30 meters without any connection problems and data loss. The USB active extension cable works like a USB hub which buffers all down- and upstream data traffic to minimize signal delay. Suitable for use with all high-speed USB devices like hard drives, printers, etc.
