25 gigabits per second — both downloading and uploading. CRN reports broadband infrastructure wholesaler Chorus demonstrated those speeds over their existing passive optical fiber network [PON].

The demonstration in Auckland achieved 21.4 Gbps throughput, tested simultaneously on the same strand of fibre that ran an 8 Gbps symmetric HyperFibre connection, and a 900/550 Mbps UFB link.... Chorus uses Nokia's Lightspan FX and MX access nodes for multiple types of fibre service, including standard GPON, the XGS-PON behind HyperFibre, point-to-point Ethernet, and envisages the 25 GPON service to run on it as well. It is based on the Quillion chip set line cards, which Nokia says are 50 per cent more energy efficient than earlier models.

Currently, Chorus has no wholesale 25 GPON product, with its fastest offering topping out at 8/8 Gbps HyperFibre. The wholesaler expects to develop a 25 GPON based services within the next two to three years, with a Nokia optical network termination unit that supports either 25/25 Gbps or 25/10 Gbps options. Kurt Rodgers, network strategy manager at Chorus, said the faster broadband service would come into its own for industrial metaverse applications, the Internet of Things, and low-latency cloud connectivity....

Chorus chief technology officer Ewen Powell said the 25 GPON service demonstrated "a future-proofed technology." Although two-wavelength 50 Gbps service is appearing as a choice for providers, with 100 GPON on the horizon, Chorus is betting that the 25 Gbps variant will offer the best cost benefit overall for providers, as it can use existing optics equipment.

      • Ok. They do not have to oversubscribe much

        • We dont have to oversubscribe at all, because our last mile is independent of the ISPs and the backbone is well funded.

          Its got nothing to do with low population numbers and everything to do with decent regulation.

          • Re:

            Sounds to me it has more to do with keeping the last mile in the possession of the people and only sourcing out deployment and maintenance as a service.

        • Re:

          Fantasy. Oversubscription is related to investment per customer. There isn't a single fixed pool of cash that is distributed equally among countries. It doesn't matter if you have 5 people or 50 million. Oversubscription is the same.

      • Re:

        Is that an argument that the should continue to deploy old tech rather than simply using new switches as the old go end of support? I'm sure the service provider has calculated the cost per port for a TCO and ROI and decided that deploying 25GbE rather than 10GbE is within the budget they designed to maintain those ports. Also, in order to build out the backbone of their network, they probably have 400GbE with channel bonding in place for the back haul. When you buy those switches in 2022, generally, the 25

      • Re:

        Naah, they just need to put in local caches for TukTuk, Pr0nhub, Fecebook and Twatter and 95% of their international traffic gets served locally.

      • Re:

        You'd be amazed at how little traffic moves to the rest of the world. There's a reason local datacentres and CDNs exist in the modern world. International links have in no way kept up broadband adoption.

    • Re:

      I can still remember my excitement when I was finally able to get a 56kbps modem for my dial-up networking activities. I should note that, at the time, when on the road I usually had to use an acoustic couple, a device useable with any phone, but which gave a typical speed of 300 bps (bytes per second!) sometimes better, sometimes worse. The progression in speed of networks available to consumers in the last 40 years has been extraordinary. Today's speeds were unimaginable in the 1980s.

      • Re:

        I saved for 3 months to afford a 28.8kbps Trailblazer modem. I needed the speed because I was running an FTP site from my bedroom.

    Does anyone not see the inherent problem with this? So they have 25 billons per second but not with the rest of the world. Great for their Kiwi porn I guess.

    • What a party you could have.

      That said, following the trends, you will need to download a gigabyte or two just to view a basic web page in a few years time. We passed thousands of lines of JavaScript long ago, will not be long before it is millions. Just because it can.

    • Re:

      Cache Netflix, YouTube, and Wikipedia. Most people access very little unique content.

      What is this rest of the world you speak of, and why should my local CDN / Netflix datacentre, or other local cashed service care?

    • Re:

      Japan has had 20Gbps fibre widely available in several cities, and 10Gbps nearly universally available in all cities, for some years now. We can learn a few things from them about how useful it is.

      Firstly most computers only have a 1Gbps network port, and most consumer grade routers can't handle 20Gbps of traffic. Even if the network is fast enough, most computers will struggle to handle that amount of incoming data. It's 2.5 gigabytes/second, which only NVMe SSDs can handle.

      Secondly the server on the other

    • Re:

      So, anything that is on a caching proxy (you remember Squid, right?) will be at 25 gbps. Any IPTV and VoIP will be 25 gbps. Any storage of photos or videos on any server nationally. It'll make NZ a great place to develop any new games, virtual worlds or similar, because you will have a larger beta testing group with adequate access.

  • I have 1 Gbps symmetrical and could upgrade to 10Gbps symmetrical for just the cost of the fiber terminator. But what for? There are very few occasions where I can even use the 1Gbps, simply because the other side is too slow. I would also have to upgrade my network cards and switches.

    • Think they do it to piss off Americans. "Sure it is useless, but so is a 1mbit internet connection."

    • Re:

      I remember this exact same argument used when DSL came out. 56kbps was more than enough to run the internet. There's no possible reason we need to develop faster links.

    • Re:

      Because Elite: Dangerous, that's why. Honestly.

    • Future-proofing, mostly. Get this in place now, maximizing the existing infrastructure capabilities, and when new technologies do become available to the end user, they're ready for it.

      A lot of new stuff comes with multi-gig ports now, 1, 2.5, and 5 gigabit Ethernet. The future is coming, and it is more bandwidth hungry and than ever.

  • So can you imagine, if the datacenter only uses 100Gbps connections for its own bandwidth, how fast these lanes will become clogged with only a few households? So I am calling this a pipe dream for the near future but it will happen someday.

    • Re:

      Of course, 100Gbps may be as fast as your datacenter goes, but it's not the maximum available speed. OSFP ports are currently out there for 400 Gbps and expected to support 800 Gpbs per port, and not every connection must be a single port. So one could imagine beefier equipment. It could be also a matter of banking on lack of coincident network demand to deliver good peak performance, despite being unable to deliver sustained aggregate performance

      Though to be honest, I don't know that in practice this rea

  • If I was running a business I'd be hesitant to put 25Gb of important traffic on a PON. I was involved with running subscriber services on a GPON network and one piece of mis-functioning equipment on a PON can be enough to knock everyone else down. The "passive" in PON is passive optical splitters, so everyone else on your splitter is either divided up by time slot, wavelength, etc. If someone's busted equipment steps on your time slot you're just out of luck until your provider sees this and removes it from your splitter.

    Not sure about newer *PON technologies, but I think GPON could allow for 128 or 256 splits, and the more thrifty your provider is the higher your split.

  • When you've absolutely, positively got to download every melon farmering link on the page all while handling 37 torrents and streaming three UHD movies and a "movie", accept no substitutes.

  • 99% of people use wifi and not a wired connection so they can sell 1Tbps if they want, people will be lucky to get 30mbps from the shitty router downstairs.

    • Re:

      So run one cable upstairs drop in an ap an the problem is solved, if you connect that ap to a poe port, or use an injector downstairs yo don't even need power at the ap.

  • There was a hospital-hospital linkup for telerobotic medicine. Eye surgery, I believe it was. Bandwidth was reserved, I suspect, which you could do for UDP traffic back then, on some routers. (RSVP protocol)

    These days, with 128-lead wearable ECGs exist. These are sufficiently good that they'll give you a 30 minute warning before a heart attack. That's a hell of an early warning system. The problem has been that this is a lot of information and, if they were widespread, the bandwidth reservation you'd need to guarantee a reliable connection to a hospital would place a huge strain on systems. Encrypting the data is now easier, so security is less of an issue. 165,000 NZers have heart disease.

    (The bandwidth for 128-lead ECG + bandwidth for a response for injecting drugs and/or inducing electrical shocks + VoIP phone bandwidth) x (largest gathering likely for a support group) reservable using some modern equivalent of RSVB in every location likely to have such a gathering, so that there's guaranteed zero packet loss, would be extremely handy. You wouldn't want that in every household, or even most, but it would definitely be something that would reduce the risks of heart disease.

    So why make it available for every household? Because making it an easy-to-obtain commodity makes it something that people can practically get without having to buy dedicated lines. It also makes it much, much cheaper, and the underlying network requirements mean that regular Internet becomes much faster and smoother.

    • Re:

      This seems like the sort of application where you'd want to have analysis of the input local to the device, rather than streaming all the raw data to a remote system. If the connection is so demanding that's one issue, another is that you want a high guarantee of correct behavior in the face of the internet connection going down.

      We don't need to 'cloud' up every service and stream all the minutia of raw data from gobs of sensors into datacenters, we should have local response loops with ability to sample a

      • Re:

        True enough, though as I recall there was terror on Slashdot when these devices came out, because of the concern of having devices injecting drugs or delivering shocks to the heart without supervision.
