The unsung hero of IDF

One technological innovation at the IDF this year hasn't received a lot of press having been overshadowed by so many other long awaited announcements and demos; an oversight that ExtremeTech has remedied with their article on Light Peak. A new data transfer standard using fibre optics that currently allows transfers of up to 10Gb/s and should scale up to 100Gb/s as it matures. USB 3.0 is certainly going to be available sooner than LightPeak but before you dismiss it you should recall one very important detail; USB can only handle one protocol at a time, a constraint that fibre optic cabling does not share.
"Intel has unveiled Light Peak, an optical cabling technology that can transfer data
between your computer and peripherals at 10 Gb/s, fast enough to transfer a full-
length Blu-ray movie in less than 30 seconds. Fiber-optic cabling is not new, but
Intel executives believe Light Peak will make it cheap enough and small enough to be
incorporated into consumer electronics at a price point that consumers and
manufacturers will accept.
Fiber optics typically use a cigarette-box-sized optical transceiver, which contains
tiny lasers and photo cells, to facilitate the connections. Intel miniaturized the
box down to the dimensions of a wafer thin dime. Optical cables are already pretty
tiny; each one is just 125 microns wide or about the width of a single human hair.
The transceiver can deliver two channels of information over the fiber-optic cable—
necessary since PCs need at least two ports. "
