back to article Submarine cable capacity doubled with flick of switch

With a flick of a switch, NTT has boosted the capacity on its Japan-US PC-1 cable link more than 2.5 times to 8.4 terabits per second. The company's announcement heralds the beginning of a rollout that will ultimately take in NTT's intra-Asian submarine cables. NTT has been trialling 100 Gbps digital coherent optical systems …

    And not a moment too soon. Do you have any idea how long it takes to slurp every bit of data on everyone over that old slow link? FFS, there are tear-wrists out there just plotting to destroy the Constitution of the United States.

      No worries Gen. Alexander, I think the NSA is destroying the Constitution just fine without any help

        But sometimes in order to defend the constitution you have to accept casualties.

        Like the constitution itself for example.

        Not only wealth but privacy too. Thanks to people like Clinton and Obama we have no privacy left in the United States. One of the problems with big government is that it has to get ever bigger and ever more paranoid in order to sustain and embiggen itself. Part of that paranoia involves destroying privacy.

        Snowden is nothing short of a hero. Anyone with a brain already knew that the government was snooping on everyone and everything without a warrant; he simply blew their cover.

        So what does this have to do with a discussion of submarine cables? Absolutely nothing. Governments don't tap into submarine cables. They simply colocate equipment at the endpoints to extract the data they want.

          The ones that *don't* enter their territory they do.

          If you think your privacy will improve by changing the flavour of your government to one you prefer, you are a fool.

    So slow

    Anyone remember the talk back in 2000-2001 about how the backbone networks & stuff had overbuilt and that we couldn't possibly use up all that bandwidth? All that dark fiber from telcos because it didn't have any use? I remember mentioning that the only reason they didn't really get used was because most of us were still stuck with dialup. And it seems I was proven right; as soon as broadband went ubiquitous, now all those "overcapacity" broadband stuff went saturated. And even now, I'm not sure if that dark fiber has been lit up, or if it remains dead in the water.

    With these upgrades, we should be able to crank up backbone bandwidth worldwide, and telcos should stop trying to ram data caps against us...

      I worked for an Asian company in Europe until recently and I must say the connectivity from Europe to Asia sucks the big one. I struggled to get a consistent 3Mbit/sec to Korea at any time of the day. This kind of news is probably quite good for companies like my former employer.

    Alcatel trial wasn't on a submarine cable... was in a lab.

    The reason is that this test was made with a new kind of optical fibre called "large effective area fibre". BTW - this is not the same as LEAF (where the "A" stands for "Aperture"). Here is an example for this new type of fibre,

    The key point is that this is not the fiber that is already under our oceans, so the Alcatel test isn't indicative of the kind of bandwidth boost that can be achieved in real submarine networks (which the headline suggested). Nevertheless it's an amazing achievement and points the way for the next generation of submarine cables.
