I get speeds comparable to FTTH providers' offerings. I don't see the problem. For now, perhaps, but it has nowhere near the potential capacity of current FTTH infrastructure. My ONT is on the other side of the wall from my router, and I don't have 50-500 other users trying to access the same node. Just because you happen to be next to it does not make you immune to possible "last mile" congestion.
There are some excellent quality cable networks out there, such as Comcast's Twin Cities region. And there are people out there with near perfect service that don't rely on FTTH, but overall I have to say that it is much more than just a silly game of semantics. And while it may not be accurate to say that FiOS is more advanced, it certainly can handle a far greater distribution of bandwidth, especially with regards to uploads. | |

16mbps and I get 17.3mbps.
2mbps up and I get 2.2mbps.
I better call and complain, huh?

| FIOS is not running a fiber optic cable from the internet to your home. They are running a fiber optic cable, passively splitting it along the way to other homes. So that one fiber optic cable is shared.
FIOS is not unlike cable, except they are using different technology and medium to split up the signals.
FIOS is in its infancy, and you may have overly congested "nodes"... the electronics and multiple fiber splits, be them passive, can not handle an infinite amount of data. Television signals coming downstream and internet usage add up, especially with HD.
We do not have FIOS here, and probably won't for the foreseeable future. But to me PON networks look a lot like a hybrid-coax network.
And never forget, there is nothing stopping cable networks from running fiber from all those node terminations to the homes. Does no one see how easy this would be? | |
|
| | | | Re: Well it is FTTN this may be true that one fiber feeds a splitter to 16-32 homes BUT the amount of data that can be transmitted over a fiber optic cable is only limited by the pon card on the co side. so as pon cards get more advanced its just a matter of changing a card and *poof* more bandwith. whats the throughput on coax? 180mb/s? and over a long distance that is decreased.
so PON newtworks are not like the coax network because fiber is NOT a bottleneck.
there is something stopping cable networks from running fiber, cost. | |

| Re: Well it is FTTN The reason hybrid fiber-coax systems were implemented where due to the distance problem. Fiber to the node then coax to the home.
Coax and fiber are comparable, the electronics portion is the limiting factor. Point to point fiber wins, because of the spectrum. But both PON and cable plants are multipoint deployments. The splitters on fiber causes loss as well as distance, in a PON network. A coax network does have some passive components, but most are active (amplifiers, there is power running on the coax along with the 1GHZ of spectrum usually used), making distance issues comparable.
Data speed on a coax network does not drop due to distance. A cable modem is either online or off. It does drop with DSL technology, not DOCSIS technology.
BOTH are a "bottleneck" because they both have limitations. Fiber, even if you start using "light" switching, quantum processors, or whatever, is limited especially in a PON situation.
If you fire a laser into a fiber optic cable, the light loses power over the fiber in correlation to distance. The more distance on a fiber cable the more loss.
What is the throughput of fiber? What is the throughput of coax?
Your simply misunderstanding physics or mixing technology with the medium it is deployed over.
Cable companies are not running fiber the rest of the way due to costs. Also why the phone company is not running fiber in my neighborhood, cost.
Besides costs, cable companies are in a far better position to launch fiber than the telephone company is. To run fiber everywhere, when the cable companies already have it "almost" done? | |

As it is limited by the CMTS on the cable headend, ergo DOCSIS3.

Same with cable. They're already doing it with DOCSIS3 by bonding more channels. They can go true wideband eventually if they needed to.
quote:

Actually no. On a 1GHz system with current standards of 38.8Mbps per channel it's 38.8Mbps * 135 channels = 5Gbps. This is of course theoretical, just like Verizon theoretically wanting to deliver 1Tbps to your home.
quote:
and over a long distance that is decreased.
Today's cable systems don't have long coax runs. The nodes are actually pretty close to the subscriber.
quote:

Verizon didn't get its fiber for free either. The cable companies had more customer facing fiber than Verizon did before it built out its FiOS network. It won't be difficult for them to do FTTH. | |

Ashburn, VA | Great job spin doctor, but you said nothing of substance in any of your comments that refuted anything that I said. The overall bandwidth capacity of the FiOS infrastructure is miles above that of even the existing DOCSIS 3.0 cable deployments. For my area, there are no more than 32 subscribers split using 2.4 Gbit/s down and 1.2 Gbit/s up. The Video portion of FiOS uses a completely different wavelength which takes nothing away from these values. Congestion is much more prevalent with cable, as it was for me when I used Comcast before making the jump to FiOS.
FiOS is not unlike cable? Sure, there are similarities, afterall, they are both attempting to accomplish the same thing; they want to provide TV, internet, and phone services to residential customers. But you are focusing only on these similarities while completely neglecting the bigger picture. I'm certain your motives are intentional. It would be like saying some junior high football squad is not unlike the New England Patriots. They both play a similar game using the same number of players at nearly identical positions. This news article was about misleading ads. I see the damage has been done. Perhaps stiffer penalties are warranted? | |
