I think they got it right...
Note the channel bonding notice at the bottom.
If you consider 2.4Gbit to 32 people @ 400mbit each on Fios theoretically that is an oversell ratio of 5.333(repeating of course).
What I think most people don't understand is this would be perfectly acceptable. That's actually a pretty low oversell ratio for residential service.
Think about this: Those of you getting 10-16mbit speeds on DOCSIS modems today remember you only have 38mbit shared between you and 30-300 friends (probably closer to the smaller number in this case). You don't even want to know the ratio on that.
And to talk a little more about the bonding - considering ~150mbps per channel for DOCSIS 3 that means they'd have to bond 16 channels to match Fios bandwidth (2.4Gbit) - all for only 32-64 customers. I don't think cable will ever put only 2-4 customers per channel.
When you compare Fios to cable, any way you cut it Fios comes out on top, until cable actually starts running fiber to your door also  |

Lindenhurst, NY | Yes but the article states he said the ont is capable of 400Mbps. EH did not say the node or anything Like that.
Thats what I am saying. The article doesnt state what the max of the service is. It only states what the Ont can handle. |

Why do they have to run fiber to your door? If they get fiber to your block, there's a lot of bandwidth in the ole coax. Hell, if the telcos had fiber to your block, there's a lot of bandwidth in copper if it only has to carry a signal 1,000 feet. Imagine how much bandwidth is in coax if it only has to travel 1,000 feet? |

Lindenhurst, NY | The article states though that the onts have a max of 400 though.
So if this guy is wrong then we cant trust this article then. |

I saw that too (I actually read the article after I posted that). I can guarantee you that on the fiber side of the ONT, they are seeing faster then 400mbits. BPON it self is rated at 622mbits download. Every ONT within a node sees all data, and filters it as appropriately based on the address of the ONT. Traffic destined for that ONT is let through while traffic destined for other machines is dropped. GPON works similar, just at faster rates.
There may be a limitation within the spec though that artificially restricts it down to 400mbits, but that sounds like an awfully round number to be a hard limit for what can be spit out the other end of the ONT.

| 622Mb to ONT; ? Mb to CAT5e for LAN
First - multiple computers / people.
Of course.
Multi-users either gotta' share a single connection's bandwidth.
Or get individual connections / fibers, for full bandwidth.
The ONT may well be sending and receiving at 622Mbps or 2.4Gbps.
But what aggregate speed is given to the user's "LAN" side for the user's Internet access?
I argue for maximum LAN bps to minimize the real time needed to complete data transfers. Aggregate data transfer remains more or less fixed, even at a gazillion bps, when the data is being processed by the human brain. (Again, obviously, not for pure data file downloading / archiving / library building / ...)
Above some Mbps, the brain becomes the slowest network link in the information processing chain.

Re: I think they got it right...
Right now FiOS is 622 Mbps... Of course that'll be for one customer
In 5 or 10 years, todays speeds will be a be a joke and we'll look back and remember how fast we used to think it was. |
