Intel showed off its Light Peak technology at IDF last year. Light Peak has been described as the future of connections since it uses fiber-optics to carry any signal you want, whether it is for a display, a printer, or external storage devices. Intel envisions Light Peak as the only connection type future computers will use since it will replace them all, even USB 3.0. However, there is a bit of a snag as industry sources close to Intel announced today that Light Peak will not use light to carry information, at least at first. Practical realities have come in to play so a more conventional data stream, like copper wire, will more than likely be used in the initial batch. Light Peak is significantly faster than USB 3.0 as Light Peak can carry data at 10 gigabits per second in both directions at the same time. However, with the transition to copper in the initial wave the speeds should not be affected much at all. Light Peak is scheduled to appear in products as early as next year, more likely in the first half rather than the second. Sony and Apple are expected to be the first manufacturers to incorporate Light Peak when it does launch.
