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.

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 haven't had a salesman come by, but they just installed Gigapower (or whatever it is) here because Google Fiber is rolling out in Atlanta. It's probably awesome, but I'm not paying over twice as much for gigabit over the Comcast service that works well enough to stream what I want. Oh, they have a special deal that looks good until you read the fine print that AT&T gets to track all your internet usage and use it to sell things to you (and probably sell you to marketers).

I've got about a dozen recorded phone calls from "AT&T solutions providers" (contractors AT&T has hired to telemarket) trying to sell me uverse as a fiber optic service.
But its not fiber in this area its ADSL2+.
Which is odd because the city sells fiber lines up to 50/50mbps.

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.

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
