Just when you thought the hip new thing to do with CPUs was using copper, Intel is
saying they
wanna
use that wacky fiber optics stuff. The use of fiber optics will most certainly be more
complex than just using pieces of metal, but also add the benefit of consuming less power
when doing its job.
Optical connections, which use laser
light beams rather than electrical impulses to transmit signals, could solve some
bottlenecks because they can run on less power. It won't be cheap or easy, but it might
become the lead alternative. Other companies are also looking at organic connections.
