With the introduction of USB 3.0 the USB Implementer's Forum has made a cut in the development history of USB. Not only has the bandwidth been increased more than 10 times, but the bottleneck of bidirectional communication has been eliminated. Nevertheless the physics cannot be outsmarted and the maximum line length decreased.
This white paper shows how to overcome longer distances at a high data rate and transmit more signals at the same time.
