ITU Give Consent To New 40Gbps Fiber-to-the-Home Broadband Standard 55

Mark.JUK writes: The International Telecommunication Union has just granted first-stage approval ("consent") to two new ultrafast Fiber-to-the-Home (FTTH) optical broadband standards. The first (NG-PON2) will support Internet download speeds of 40Gbps (Gigabits per second) and on top of that the new XGS-PON aims to deliver a symmetric 10Gbps service (same upload and download rate). By comparison, the previous XG-PON standard only ensured an asymmetric speed of 10Gbps download and 2.5Gbps upload. Now all we need is computers, Internet services and Wi-Fi networks that can actually harness such performance in the first place.

    Nobody needs more than 640kbps.

      Gigabit broadband has been available for I think over a decade now in Japan. It's actually kinda old hat, I posted a story a while back about the discontinuation of ADSL meaning that gigabit fibre is all you can get for new installs now.

      The thing is, it's gigabit but shared between a number of households, say 3 or 4. If you are lucky you might get it all to yourself, but probably not. A 40GB pipe could offer more bandwidth per customer, and more customers per fibre which means cheaper installations.

        It's easy to provide fibre-to-the-home when everyone lives in high rise apartment blocks. You just get some string, tie a weight to the end and let it haul the bundles of fibre optic cables down the risers in the building, then hook them out into each home. With cities in Eurpoe and the UK, there are thousands of streets with paving stones that have to be dug up, fibre-optic cables laid and connected to each home.

        Everyone wants to get fibre-to-the-home, but there just isn't the investment. Hyper-Optik have

          Most Japanese people live in detached houses. The fibre is usually on the same poles as telephone lines and/or power lines.

        • At least in Europe, generally speaking, houses are built much closer together than they are in North America so it's cheaper to roll out fibre.

    • You jest, but some congressmen have criticized the FCC for setting the definition of "Broadband Internet" at 25Mbps. These politicians (and the ISPs that paid for them) think we'd be just fine with 10 Mbps and they can't imagine any use where we'd need faster.

      (Personally, I'm stuck on 15Mbps Time Warner Cable and really wish the network faster and more reliable.)

        While I agree that progress in broadband delivery has been too slow and hampered by profiteering and invented technical limitations, I can almost see why some kind of fairly high speed standard might cause issues.

        I have 15 Mbps and we seem to have no problem with two HD video streams, concurrent web and remote access sessions at this speed. I'd like faster, especially upload, so that moving 20 gigs over the net was much faster, but what exactly is the usage baseline to be established with 25 Mbps? 3 4k str

    • I have 100Mbps fiber home optics. I can upgrade it to 200Mbps, but have no real need. 100Mbps - from local trackers I can torrent 4.7GB file in 10-15 minutes, netflix ,youtube on HD whatever works flawless. I indeed cannot imagine why I would need something faster than 100Mbps. Btw - most home routers cannot handle even 100Mbps... 10GBps - how can I utilize this ? I am not sure my computer cpu can handle such amounts of data.

    First we need ISPs to provide broadband service.

    We can't buy it if they won't sell it.

      Now all we need is someone willing to run fiber to my house.

      Oh, they'll sell it . . . folks will buy it . . .

      . . . but the ISPs won't deliver the speeds that they promise . . .

      • by sims 2 ( 994794 )

        probbably not but if they just provided 1% of the speed listed in the summary it would still be faster than anything available in town by a full 50mbps.

      You can buy this service right now from EPB in Chattanooga.

  • 40GBs split 16:1 or 32:1 at the local node should give each home 1GBS each way.

    • Yea but you could split it 256:1 then still charge for a gigabit line that you get 5-10% of the time. It's what every ISP in the USA does with their 100mbit home service!
      • by Bengie ( 1121981 )
        You underestimate 40Gb/s. That's probably nearly as fast your ISP's local trunk, but instead of sharing that with 100k people, you're only sharing it with 256. Few ISPs use a 256 split because of the signal strength reduction.
        • by Shatrat ( 855151 )

          TWDM-PON only supports 128 way split. GPON only supports a 64 way split. Many ISPs are conservative and only do a 32 way split on GPON anyway just to give themselves more leeway for fiber defects.

    • by Bengie ( 1121981 )
      WDP-PON is 40Gb split 32 ways with a dedicated 1.25Gb per end point
      XG-PON1 is 10Gb down 2.5Gb split 32 ways, non-dedicated but up to 10Gb per device
      XG-PON2 is 10Gb down and up split 32 ways, non-dedicated but up to 10Gb per device
      TWDM-PON is 80Gb down and up split 32 ways, non-dedicated but up to 10Gb per device
      NG-PON2 is similar to TWDM-PON, but caps out at 40Gb for the current implementation. Where it really stands out is the standard should scale up to 25Tb/s with 100Gb per customer. This makes it de
      • by Shatrat ( 855151 )

        TWDM-PON can actually split up to 128 ways. Most PON standards support at least 64. 32 way splits are just a conservative approach that many ISPs take. None of it really has much to do with how much bandwidth you can sell in practice. Most ISPs are going to hit backhaul and IP drain limitations long before they congest any of their PON access layer.

    Fantastic! Yet another high-speed standard that will be completely ignored by the telco oligopoly here in the US. At least Europe and Asia will benefit.

    • Europe won't benefit. We'll be lucky to see a roll-out of 1Gbit FTTH, which is being lambasted by some telcos as being too expensive. Then there is the problem of backhaul, and the fact that for now even speeds of 10Mbit are 'good enough' for a lot of people. They'll take higher speeds, but not willing to pay the monthly bill
  • Wi-Fi networks that can actually harness such performance

    Decades of GBits/second of speed over WiFi? Good luck with that. Either it needs to be broad-spectrum 'just above the noise floor' (other words for 'it drowns out all other weak signals' ... can create havoc on things like GPS reception) on the conventional bands, or we need to develop radio transmitters that can broadcast in the THz spectrum. Maybe use light for wireless transmission? (Light has a frequency of 400-800 THz)

    To transmit a signal with a certain information density, you need a bandwidth at leas
