Re: It'll never work
said by Rob A  :No one on cable with be able to hold 20Mbps/2Mbps consistently and will be capped very easily. And not to mention, when this things goes final, Verizon will just flip a switch and upgrade their speeds with no hassle. Just because FiOS is fiber, doesn't mean there is an unlimited amount of bandwidth. Verizon can't just "flip a switch" without gaining more bandwidth from their end, it's common sense. FiOS is still a shared source, just like cable.

Answer these 2 questions. How much throughput per channel on cable nodes and how much per channel on fiber ?
Then rethink the statement.

You seem to be countering your own point. Yes, the whole internet is shared, and yes, you are limited by the weakest point. But even with cable, your home connection is often not the weakest point. I "only" have 8MB cable, yet my download speeds are still frequently limited by the source. Very few of MY common everyday sites can saturate my pipe. Of course, that only holds true for downloads. Pure download speed is not what's attractive about FIOS. It's the upload speed, and lack of a download cap.
But I think an earlier sentiment holds true: for most of the market, the differences aren't great. |

Well I do realize that cable companies over sell their nodes thus limiting the bandwith but if cablevision were to put more nodes out there shouldnt be a problem.... But I do agree with you fiber is the future but how far away that future is. Is up to how the cable companies run their systems |

Most people who are tech-savvy or teenagers in need of porn/movies/games will find everything they want at the speed they want
4years ago i could get access to the local university's connection a couple times a year(back then the standar broadband speed was 1.5mbps here)
back then they were still people like you saying ohh most sources cant handle over 4-6mbps
Then why the heck could i download EVERYWHERE i went at over 10mbps? Most webhosting companies offer at least 6-10mbps, most torrents have enough people to go at 10mbps especialy if its a private tracker, most irc chans have 10-100mbps bots, most high-tech companies have big pipes
dont forget the linux distros these are on the biggest pipes ever i could even get 25mbps from free.fr here in canada |

Well, on a 800mhz system, there's 133 6mhz channels. At QAM256, that's 38mbps per channel, or 5054mbps per fiber node shared amongst everyone connected to it.
At the moment 70-90 of those channels are being used by analog cable on most systems. And of course all the digital cable and HDTV channels. Can you see why they want to switch everybody to all digital now? That analog cable takes up an enormous amount of their available bandwidth.
Bottom line, there's really an enormous amount of bandwidth that can be pumped through coax. It's just a matter of management.

FiOS is still a shared source, just like cable. For the most part cable can't compete with FIOS. FIOS can handle multi-gigabit networks, the problem is the cost of peering with the actual internet, that is why we only see 15/2 in 2005 and not 1500/200 like in the future.

Bottom line, there's really an enormous amount of bandwidth that can be pumped through coax. It's just a matter of management. While I agree I must say that that is the problem they are packing channels. 38 megs per channel and a whole city using that channel. Or even a whole node using that channel.
FIOS 622 mbps per channel. You see my point I hope by this time. But I will keep going. 32 Users per channel, not a whole city. Less shared means less likely that little johnny can completely suck down the bandwidth if him and his friend decide to fire up bit torrent with 20 mbit links.
In order for cable to sustain 20 mbit + links. They are going to need a major addition of line cards. Then they have to dole out 5 or 6 people to each channel. Can that even be done with some sort of reliability ? Docsis standards with other technologies may help but there is less likely that fiber will be bogged down.
Then we are still down to the slowest part of the last mile being our cap. In this case for cable the channel per node and for Fiber the amount of money they want to spend on thier equipment
