Terabit Ethernet Inches Closer To Reality

An anonymous reader writes "Researchers from Australia, Denmark, and China have combined efforts to show the feasibility of terabit-per-second Ethernet over fiber-optic cables. The solution involves a photonic chip that uses laser light for switching signals, and a form of the exotic material type, chalcogenide, or arsenic trisulfide."

      Being someone who works at a porn company with multiple dedicated lines buried under the ocean, I can say this is very true. We test all the equipment we have to the limits.

      I worked for a lot of mom and pop companies that thought they had problems.

      We are pretty much a dedicated Foundry and Cisco debugging team.

      When a single server gets over 10,000 hits a second (yes, second, not minute) - it tends to stress your equipment.

      Times that by a few hundred servers and you get the idea.

      I used to deal with simple PHP and Apache issues before. Performance? Was never an issue.

      Now half our stuff is written in heavily optimized C, our kernels are heavily tweaked and even Squid isn't fast enough to keep up.

      We even have our own custom caching software.

      On a large enough sample set, correlation implies a relation other than chance, and thus should be investigated. Otherwise you can keep screaming "Correlation is not causation" at every piece of data every produced and try to claim that we can never claim results.

      After all, if I state that "Each time a plant is deprived of water and sunlight it dies.", stating "Correlation is not causation" is complete nonsense. We've observed over a large enough sample set that yes, in this case correlation damn well IS causation. Effectively, your only argument here should be whether or not the sample size is large enough.

    If you have, say, a bundle of fiber running across the Pacific that would cost you 9,334 bazillion dollars and a battle with the giant enemy crab just to upgrade; being able to increase its capacity just by upgrading the hardware on each end is a very attractive proposition. This applies, to a lesser degree, in all but short run situations.

    This isn't exactly destined for workstations in the near future(heck, neither is 10GigE, and that is more or less commodity-off-the-shelf stuff by now); but there are applications where higher speed per fiber could well be desirable.

    The solution involves a photonic chip that uses laser light for switching signals, and a form of the exotic material type, chalcogenide, or arsenic trisulfide."

    Once you have the photonic chip installed, you will need to realign the deflector shield to output a graviton pulse through the arsenic trisulfide to create an anti-tachyon pulse which will modulate itself based upon the resonant frequency of the transport medium, thus allowing for longer distance transmittal of data than is currently possible.

    Granted, it will take 15 years and research team of a hundred to complete, but it is doable.

      Okay, I'm the author of the Ars Technica piece, and that make me laugh.

      Talking to the researcher, Eggleton, made my head slightly explode, because he's looking 5 to 20 years into the future with the research he's on top of today.

      But they have practical devices that show that the stuff can be hand-built, and that's what blows my mind.

    I suppose you forgot about internet back bone links. Terabit Ethernet should hopefully enable Tier 1 ISP's to provide really fat pipes to ISP's so we can finally get more bandwidth. The bigger the backbones the faster our broadband can be. Well at least that's my fantasy. 100mbit boradband should be cake walk with tubes that fat.

    The article doesn't say how far they can send the terabit signal, only that the receiver requires 5 cm of fiber to split the signal into lower bandwidth pieces. Presumably the distance between sender and receiver is longer than that.
