Intel has unveiled technology called Light Peak that it hopes ultimately will replace the profusion of different cables sprouting from today's PCs with a single type of fiber-optic link. The cable can be as long as 100 meters and can carry data at 10 gigabits per second in both directions simultaneously, though Intel expects it will reach 100 gigabits per second in the next decade.
It's not clear how much the technology will cost or how many years it will take to become mainstream. And wireless communication technology--Intel itself has promoted Ultra-Wideband (UWB) for years--offers the attraction of getting rid of some cables altogether.
Intel also said it's working on bundling the optical fiber with copper wire so Light Peak can be used to power devices plugged into the PC
