Transfer at USB 3.0 speeds (also known as USB Super Speed) and overcome USB's distance limitation of 16 feet with Sewell's Active Link extension cable.The cable is 10 feet long and allows 30 feet USB 3.0 extension (at least).

USB's Distance Limitation

The USB consortium specifies USB (USB 1.1 through USB 3.0) to only effectively transfer data and commands over 16 feet at the most. If you've tried to go further than this without an active booster, you may have had mixed results: either a slower transfer rate, no transfer, or corrupted files. After 16 feet you begin to experience "data packet loss" which either slows the transfer or fails it completely.

In order to guarantee optimal performance over copper cable runs longer than 16 feet, this cable includes an active booster that repeats the signal and allows it to be sent over a total of 30 feet without unnecessary packet loss.

USB 3.0

The USB 3.0 standard has increased the data transfer speed to a theoretical 5 Gbit/second. This speed of course depends on many other factors, including the host computer's processor and hard drive capabilities. The USB consortium says it is reasonable for you to get 3.2 Gbit/second (.4 GigaByte/s or 400 MegaByte/second) out of USB 3.0, but again, a lot depends on your whole system.
