As USB 3.0 begins to make an appearance on the latest motherboards and add-on cards, so Intel has shown it's logical successor at their Developer Forum currently running in Beijing.

Light Peak currently runs at 10Gbps, a fraction over twice as fast as USB 3.0, and Intel have suggested that the optical cable technology could be tweaked to 100Gbps. Cable lengths can run to 100 meters, and the cables can pass signals from multiple protocols. One interconnect could carry USB 3.0 data along with HDMI signals to a monitor for example.

The Beijing demo used a USB-sized port which carried the usual USB copper cable in addition to the new Light Peak signal, making for a painless upgrade path. For the future, the Light Peak port could be much smaller, good news for phones, cameras etc.
