Intel Says Its Light Peak Optical Cables May Succeed USB

Intel sees its Light Peak technology for linking devices by optical cable as potentially succeeding USB 3.0, a change that in several years could mean the disappearance of a port used almost universally in gadgets today.

Intel, which announced Light Peak last year, hopes it will be broadly used by devices ranging from PCs to consumer electronics and other gadgets, said Kevin Kahn, an Intel senior fellow, in a speech at the Intel Developer Forum (IDF) in Beijing. Intel will make the technology available late this year and expects partners to start shipping devices with it next year, Kahn said.

 



"We view this as a logical future successor to USB 3.0," Kahn said. "In some sense we'd... like to build the last cable you'll ever need."

A trend toward optical instead of electrical links raises the risk that separate optical cables could appear for many protocols, such as USB and serial ATA, said Justin Rattner, the head of Intel Labs, on the sidelines of IDF. Light Peak can run multiple protocols at the same time over one line, so all the data meant for the separate cables could run through one Light Peak cable instead.

USB is currently widely used to link between devices. Gadgets often made with USB ports include computers, mobile phones, digital cameras and external hard drives.
