Hardware, Embedded Systems Intel and others plan to release a new version of the ubiquitous Universal Serial Bus technology in the first half of 2008, a revamp the chip maker said will make data transfer rates more than 10 times as fast by adding fiber-optic links alongside the traditional copper wires. Intel is working with fellow USB 3.0 Promoters Group members Microsoft, Hewlett-Packard, Texas Instruments, NEC and NXP Semiconductors to release the USB 3.0 specification in the first half of 2008, said Pat Gelsinger, general manager of Intel's Digital Enterprise Group, in a speech here at the Intel Developer Forum.

I find that hard. Have you seen a fiber optic network cable before? You have to have a sheething that protrudes into the device in order to protect the light emissions from outside the device and cable. Building that into a current USB cables would not produce a cable that would still work in older USB revisions.

And if they make it thinner, then it will likely be very likely to break.

Either way, you still have the issue of people trying to plug the old USB cables into new USB3 devices and wondering why they are not getting the speed they expected. So my original point is still valid.

The only real solution is make it a different cable - perhaps a USB C/D cable, instead of the current USB A/B would be the only way to avoid confusion (then the devices would have to support both to be backwards compatible, or at least the USB3 hubs and root devices would have to) - but then you'd just as well call it something else.

But USB already has that, the metal shield around the USB plug would act as a light shield, it'd be tricky, but you could build the optical coupling into the end of the plastic insulation that the contacts are mounted on. The tricky thing is getting the alignment right.

Yes, USB has the metal shielding, but you need a non-shiny, non-reflective shielding that is tightly wrapped to the fiber - which is why a lot of fiber cables uses a plastic or rubber shielding on the end.

So no, that wouldn't likely work.
