Intel confirms copper-based Light Peak is ready for implementation

Posted on Monday, January 10 2011 @ 18:00:06 CET by

Intel's David Perlmutter told IDG News Service that Light Peak is ready for implementation, although the first builds will be based on copper rather than light. He described Light Peak as a medium by which you can do things, and hinted at a co-existence with other technologies like USB 3.0. Unfortunately, Perlmutter didn't share a launch date.
Light Peak, announced in 2009, was originally designed to use fiber optics to transmit data among systems and devices, but the initial builds will be based on copper, said David Perlmutter, executive vice president and general manager of Intel's Architecture Group, in an interview with IDG News Service at the Consumer Electronics Show in Las Vegas.

"The copper came out very good, surprisingly better than what we thought," Perlmutter said. "Optical is always a new technology which is more expensive," he added.

So what is it that Light Peak brings that we don't already have with USB 3?

USB 3 has
same top speed
option to go optical (built into the USB 3 spec)
backward compatibility in the same connector
lower cpu overhead than USB 2
full duplex

Lightpeak seems unnecessary and 2 years behind USB 3 which is already widely adopted. But maybe Intel can explain this to us...
