Intel Shows Off First Light Peak Laptop

Barence writes "Intel has provided the first hands-on demonstration of a laptop running its Light Peak technology — an optical interconnect that can transfer data at 10Gbit/sec in both directions — at the company's inaugural European research showcase here in Brussels. Intel has fitted Light Peak into a regular USB cable, with optical fibres running alongside the electrical cabling. Intel provided a visual demonstration of how data is passed through the cable by shining a torch into one end of the cable, with two little dots of light visible to the naked eye at the other end. The demonstration laptop was sending two separate HD video streams to a nearby television screen without any visible lag. The laptop includes a 12mm square chip that converts the optical light into electrical data that the computer understands."

      You do realize that cable television was an analog signal that required a special box to decode for years...

      Actually it mostly needed the special box just to tune it - frequency shift the normally-structured 6 MHz bandwidth TV signal to a frequency where the TV would receive it.

      Early "premium channels" were "encrypted" by inserting a strong but narrow-band interfering signal in an otherwise empty slot in the signal, near the sound carrier. This would intermittently "capture" the FM sound decoder and paint bars across the video, jamming the picture and sound. Subscribers had a narrow-band notch filter installed in their feeds to remove it.

      (There were other systems, too, including one used on "air" channels which selectively lowered the strength of the vertical and horizontal sync signals to below the level of the video. A subcarrier in the sound provided the information necessary to identify and boost the sync signals back to normal.)

    We also had users on the high speed network that needed to process large segments of the company's data from the fileserver which usually involved reading it into memory processing it and writing back the changes. All of these little exercises would have benefitted from a faster bus speed on the motherboard.

Having some sort of 10Gbit interface on the File Server would bring it back to drives, but as cheap as Ram is today I clearly would have bought 32GB or RAM and cached the contested data on a Ramdrive.
