A 512Gbps Fibre Optic Network? Yes Please

Fibre optics are the future of data transfer, no matter what your opinion on the NBN. But in Germany, the future's already here: Deutsche Telekom has a working 512Gbps optical fibre that's working in the real world. I want it.

Yes, that's a single optical fibre. It's capable of hitting transmission speeds of 512Gbps in test conditions, but real life takes that down to a usable limit of 400Gbps. No matter: when a single strand of optical fibre can stream what is the same as 77 CDs of music being played at the same time, I won't quibble over that difference.

Most impressive is the fact that this isn't a laboratory test piece; this is being used over a 500 mile stretch, between Berlin and Hanover, alongside the company's usual 10Gbps line. Deutsche Telekom explains that, if they rolled this out using their usual 48-channel optical fibres, they could achieve a throughput of 24.6Tbps on a cable thinner than a human hair. Want. Want, want, want. [Deutsche Telekom via GigaOm; Image: kainet]

    ffs, it doesnt matter how fast the access network is, unless the 'server' or 'origin' can match those speeds! i you were running a 512Gbps link accross two houses connected to an ISAM (or like device) that can process the data through it's backplane at those speeds then maybe you could use it for something???

    but seriouly, not going to happen for a long time without almost endless $

      What about businesses that have hundreds of computers, connecting them all with 1 link is amazing. Also internet works on supply and demand, if everyone had 400Gbp connections data centres would start getting major upgrades, thats good for everyone.

        I happen to oversee 2 very large data centres in Australia and i can tell you that having 10Gbps connections to each VM is amazing in itself - let along anything more. we have 240gbps connections per HP C7000 chassis, filled all with HP BL460c G7 blades (which hold the VMs).

        the trunk connection from the Cisco 2232s to the 5548s is only at 80Gbps which is a bottle neck in itself! then we have the 7018s that connect the multitde of 5548s together which have backplane bottlenecks as well.

        currently, 99% of 'datacentres' have a north-south network arcitecture, meaning that there will always be a 'core' and thus a bottleneck of some sort. I am looking at deploying some Juniper east-west switches which might allow for 140Gbps accross each c7000 but still, no where as fast as the access network can support.

        we are upgrading our SMOF backbone to 100gbps at the moment, and even that is an amazing feat.

        so no, having a faster access speed still means squat.

      Don't forget that this stuff is a way of future proofing. Even if they can't make full use of it now, they won't have to lay fresh glass later when they can...!!

    Wow - hope Alan Jones doens't read this article - he'll be banging on again about how the NBN is redundant! Still the more of a fool he makes of himself (is that even possible?) the better...

    NBN isn't reduntant. It's just expensive.
