Fiber On Your Motherboard...Soon!

    This would put SCSI on the skids. Right now SCSI is the only really fast interface commonly available between devices, but it's cost has kept it from becoming the standard. But if you could just plug in a fiber connection, you'd be rocking. Another thought is that fiber network cards wouldn't be far away. It'd be cool to buy a LinkSys Fiberboard at CompUSA for 30 bucks and be able to network all of your computers in house that way. Of course wireless technology is already pushing the limit farther.

    Also, Time magazine reported last year about this, and they pointed out that the kind of speed offered by fiber is the only real bottleneck to creating a truly self aware computer. They also mentioned that MIT was working on a Laser circuit, where logic is figured out by the paths of a laser moving through space.

    The only real application of this at the current time is in device to device communications. We'd have to rework all silicon chips to use the new protocols.

    Another problem is that we'd still have the silicon-to-light translation bottleneck. i.e. and electrical signal from a pin on a chip needs to be converted to laserlight somehow. To make this truly work, you'd need a chip that reponds via light, and I haven't seen any IC's that communicate via light yet. Of course, I doubt that they are very far around the corner.

      An already-existing attempt at fiber interconnect is called "Fibre Channel". It is fast, and can be hubbed/switched like ethernet. In fact, you can run TCP/IP over Fibre Channel. It is expensive, but you can have very long loops running very fast without EMI (electromagnetic interference). Here's a link to the industry group's technical overview.

      Hal...open my CD-rom drive door!

      Hal:I'm sorry dave, I can't do that.

      Hal, I was just getting the source code for vi off that redhat disk -- I swear!

      Hal:Open source is like pac-man. All your base are belong to us. You are on the path to destruction.

      NOOOOOOOOOO!

    Man, if you want a head rush, try this sometime. Adjust your slashdot settings to -1, and read _everything_ for about a week. Then set it back to whatever you're used to.

    Whatever you're used to will seem stale and boring. "Where's all the crackheads?" You'll think.

    I like -1, but man it's a lot to read... Nice

    Man, it's got to be that Wesley Crusher dude we were asking questions of. I told him to keep his stinking sweater away from my motherboard, but he was all "I'm in StarFleet, I'm Special" and all that.

    At least I kept him away from the daughterboard ...

    Dude, SCSI already runs over fiber (fibre). The SCSI-3 spec for SCSI-FCP is for Fibre Channel.

    Fibre Channel runs at 1Gbit serial FDX (for 2Gb throughput) and 2Gbit adapters are available. They are also looking at 10Gbit technology.

    Most really high end storage uses fibre channel.
