World's Biggest Fibre LAN Is At This Nuclear Weapons Lab

Sandia National Laboratories is America's premiere nuclear weapons research facility. For more than 60 years, its researchers have poked and prodded the interiors of atoms to suss out their secrets — a task that has produced mountains of data that the facility's copper network struggles to contain. But now even the most remote building's on Sandia's campuses have access to the biggest bandwidth modern technology can muster.

"Whether it's a materials science problem or modelling an event, we need a lot of data and a lot of processing capability," Steve Gossage, a senior engineer at Sandia National Laboratories, said in a press statement. "We need to be able to see it, we need to be able to view it, we need to be able to put teams together. This is a large laboratory, deeply stocked with scientists and engineers and test labs. For the analyses we get, the problems are not small and they're not easy."

But for Sandia's previous copper wire network, tying together 13,000 network ports in 256 buildings across a pair of campuses covering nearly 8700 acres proved immensely challenging. And for buildings beyond the standard 100m operational radius for wiring closets, such as the National Solar Thermal Test Facility, broadband speeds were a pipe dream. What's more, each network — voice, data, wireless and security, for example — required its own set of 4-inch copper cables as well as rooms full of switches and routers and miles of conduits carrying the wire.

The passive fibre optic that Sandia has installed, on the other hand, uses a single network of optical cabling consisting of 288 individual fibres and requiring a fraction of the conduit space and a network switch the size of a microwave. Not only will the new fibre network save space, Sandia officials expect to the facility to save $US20 million over the next five years alone through a 65 per cent reduction in energy usage and reduced equipment maintenance costs. "We're at 10 gigabit-type rates and looking hard at 100," Gossage said.

"As we research and deploy new technologies, our main objectives are to enable the labs' mission, decrease life-cycle costs and if possible reduce our footprint on the environment. With the deployment of passive optical networks we have been able to meet and exceed all of these objectives," said Sandia manager Jeremy Banks. To that end, Sandia officials have announced that they'll be recycling its new-found bounty of copper wiring for an estimated $US80,000 and use the proceeds to help cover the new network's $US15 million price tag.

    288 fiber cables is the largest? really?

      I think for a single geo-graphical institution (uni, labs, etc) it is. I'd guess there would be commercial sites with much more (Google HQ, Akami, etc)

        might be so, but it is a misnomer to call it the worlds biggest fibre lan then.
        add a qualifier of research institution or something.

    SNL is building a NBN and no one is complaining?!?!. Can we get the same power savings with our NBN over the copper system that SNL will get?!? .

      More power savings.
      Their traditional switched network using copper was RJ45, using modern-ish switches and routers.
      Our network uses RJ11, single pair copper, and ENORMOUS relays taking up entire exchanges, and this is before it even gets into a switch anywhere....the power savings we will have will be MASSIVE in comparrison.

    Anybody else see any irony on this?

      Fibre = way less power, = way less environmental impact.

        The irony being that detonating just one single nuclear device would have a greater impact on the environment (in the vicinity of the blast at least) than all the power that facility has EVER consumed since it was built - not the mention the environmental expense of manufacturing the new hardware.

        If they really wanted to reduce their impact of the environment, they should stop researching weapons, and start using the facility to research clean disposal methods for nuclear power!
