Re: Canada's Internet in 2100 LOL **** Videotron current node size: 125
10GPON max PON size: 128
DOCSIS 3.1 offers the same capacity (downstream) as 10GPON. If Videotron needed to get smaller node sizes, a single split gets them down to half that. Not cheap, but not unfeasible, and there's not really much point, because their current node size is perfectly fine for 10 gigabit speeds. They can sell people gigabit connections without requiring a node speed; that's only 12:1 contention, which is rather low for those kinds of speeds.
Consider that Google Fiber, if they're maxing out their PONs, has a ~26:1 contention ratio. They're selling symmetrical gigabit connections, but they're NOT using 10GPON.

O yeah, ditch witch... i saw them use it on the main road here... maybe that was phase 1, to run it along the main road, then sideways onto the small street... still would be challenging as they'd have to basically dig everyone's lawn... i wonder if they will do it, if they will prepare the entire street with conduit first. Anyway, I think i'll be stuck with VDSL for a while... How new is your subdivision?
The theory will be that something will need replacement probably in the next 50 years...so...probably in the next 50 years they would do it simply because if the city is tearing up the street to replace water/sewer, they might as well go in at the same time? 
I know its probably not what you want to hear but...that's probably when they'd dig everyone's lawn...
Or maybe there will be a less invasive way to get wires to homes in underground areas.... |

said by FTTHTechie :Considering that copper has an average lifespan of roughly 30 years whereas Fiber has about 100 it's obvious that fiber makes more sense to install. What kills an otherwise properly maintained and installed copper cable is environmental aging and physical damage.
Fiber cables are not exempt from material wear/aging and will need to be replaced just about as frequently for the same reason regardless of how long the glass component's lifespan might be. |

Fiber cables are not exempt from material wear/aging and will need to be replaced just about as frequently for the same reason regardless of how long the glass component's lifespan might be. Most of the copper wiring that is deployed in the GTA is roughly that lifespan (10-20 and in some cases 30 years) that Bell originally laid/deployed. There's also cases of physical damage and environmental influence in some areas where Bell copper has been deployed.
It wouldn't make any sense to deploy new copper in the areas where the copper is somewhat dated and aged. It would be easier to lay down FTTH or at least FTTN as an interim and that's what Bell is doing. |

said by HiVolt:I just wonder how they will do a street like mine... everything is underground, and NOT in conduits... its buried raw about 5-6 feet down. I saw it when they were fixing my phone line a couple years back.
House power wires, cable tv, phone copper just laying next to each other...
Just pay some guy with a backhoe to 'fix' it for you, so the utilities will be forced to 'fix' it correctly.  |

No new copper pulled behind my house in nearly 50 years, according to long-time neighbours. |

That's wishful thinking.
Avenue Road (6 lanes) in Toronto was completely rebuilt about 12 years ago (new road base, the works) - no new ducts were installed under it then. Over the past 3 years it was torn up again for a new water main - no new ducts installed. Six months after it was paved, they rip parts of it up to install ducts.
None of these assholes will EVER co-ordinate their activities unless there's something like a $1MM fine per KM or part thereof charge for EVERY cut they make within 5 years of a road/sidewalk reconstruction. And I mean for EVERY cut - if cuts are made 10m apart, that's a $2MM fine payable. |

They should go to Sweden or South Korea or other highly developed FTTH countries to learn how to properly install and maximize the efficiency of the ducts or at least hire specialists from there. |
