– Lucent claims 100-Gbit Ethernet over 2,000 km — Sounds like this could come in handy.

The new effort used a prototype lithium niobate differential quadrature phase-shift keying modulator developed by the Japan National Institute of Information and Communications Technology and Sumitomo Osaka Cement Inc. Ethernet data packets were successfully multiplexed and demultiplexed using the modulator hardware, similar to modulators used at 40 Gbits/sec.

While the new technique uses multiple 107-Gbit channels, the overall goal was to show that a single, serial channel could carry a signal in excess of 100 Gbits/s—first at 400 km, then at 2,000 km—and that multiple channels could be transmitted.

    oh yeah, those things are great. i keep several laying around the house in case i need them

    Nerd. 🙂

  3. Lucent once bell labs invented the transistor!

    this sounds like an interesting post, although its hard to tell as you haven’t bothered to exxplain it. this is a techy blog but this post is too number heavy.

    This would be great for Bittorrent. SIgn me up! LOL

    Fine, but what I want is that sort of speed over the 50 metres from my local telephone excange to my house!

    I just want reliable 1.5Mb/sec from my damn cable modem!

  8. Jägermeister says:

    Good… now, if we just could get 100 Mbit/s to our houses like South Korea and Sweden… 😉

    This is really going to maximize the performance of all those 1.5 Mbit DSL connections and dial-up users out there!

    Yeha, here comes the HD pr0n!!!

    I used one of these to “Pimp My Ride”!

    Ya know, I’ve spent some amount of time chasing down the hotlinkers to my graphics so the bandwidth won’t go through the roof which I shall end up paying. I take a breather for a few days…. and what do I find around 7,000 hits with your domain as the culprit. I’m amazed so I have a look around, this is a well know guy he must have used my actual link NO WAY would he have HOTLINKED to my graphic.

    Alas I’m so wrong, not only as he not done that. He’s actually used my graphic for something totally unrelated to art even. To add insult to injury. So to cut down on your own bandwidth you routinely hot link to other people’s graphics? I thought it was only the little numpty teen morons on myspace, friendster, xanga and the other natty setups that did that kind of thing.

    No….apparently not.

    So I don’t expect this to get posted, I do expect you to take off my copyrighted graphic from your site and stop hotlinking. It’s not so much the stealing of the graphic, (in this case this one is just a bite out of the whole graphic) it’s the hotlinking thing that gets me in each and every case, don’t people think any more?… 🙁
