Palm Desert, CA | What else is new, but just for the Present! With DOCSIS 3.0 the Cable Companies could Dominate today, but does that technology have enough Bandwidth to compete with FTTH? Remember everything is going to be coming over that DOCSIS 3.0 Coax, High Speed Broadband, Phone, HD TV, and HD Video. I really don't think it has the Bandwidth to compete with FTTH. Right now Verizon is the clear winner! |

After five years I got tired of waiting for an upgrade and after ten years without TWC in my house, I ordered RR last month. All I'll say is, so far so good. If and when FIOS is available, I'll reassess. If DirecTV follows through with 20Mbps down in 2012, that's another option. Right now, RR, no D3 yet, is my best option for Internet connectivity. |

Remember that signal is having to travel 22,000 miles each way -- there is no way around the latency.

Right now Verizon is the clear winner! The cable companies can upgrade to FTTH if they wish, later on when it's appropriate, since a large portion of their network is already fiber.
Right now there just isn't much need for FTTH services if you can get the same bandwidth via DOCSIS3. Even Verizon only has about 480Mbit/s with their GPON architecture. Yes, more speed can be had later on with XGPON but they'd have to upgrade.
Broadband, phone and HDTV, DOCSIS3 and phone aren't the major bandwidth hogs. Analog is. Once analog is gone there will be plenty of room. |

Yes it does have the bandwidth. First off verizon dropped their analog and cablecompanies are too. That frees up a lot of bandwidth.
Some companies like cablevision switched to sdv . That frees up more bandwidth.
Docsis 3 also allows you to move upstream to above 850mhz which frees up more bandwidth.
between docsis 3 and other ways of freeing up bandidth the cable companies have nothing to worry about.
Especia;;y considering verizon refuses to light up whole communities with fios. Even communities where they have contracts already. |

480 Mbit/s? Nope.
BPON: 622 Mbps down, 155 Mbps up
GPON: 2.488 Gbps down, 1.244 Gbps up
10GPON: ~10 Gbps down, ~2.5 Gbps up
Shared between at most 32 (BPON) or 64 (GPON) customers
DOCSIS 3: Nx38 Mbps down, Nx30 Mbps up, N=4 for downloads and 1 for uploads right now, though it'll eventually be 8 for downloads and 4 for uploads.
Shared between 125-1000 subscribers (I think Comcast is around 250, Cablevision is in the 60s, Suddenlink is in the 100-200 range for their upgraded infrastructure, significantly more for their older stuff)...
Whether Verizon is actually using their GPON architecture to its fullest capacity is a whole other deal (they aren't) but you're drastically underestimating the capacity of the current fiber architectures out there. |

The Video has nothing to do with internet bandwidth on FIOS, FIOS has three frequency's for light on the Fiber, one for Phone, internet and Video. Drop analog channels was to have more QAM space for HDTV |
|
| Yes i know that but it still freed up space for them to do add more channels Just like it would on the cable end. |

| reply to iansltx
So in other words I actually overestimated the bandwidth per home.
2.4Gbit/s divided by 32 homes is 75Mbps per home.
And before you go telling me that it can be upgraded to XGPON or 10GPON, I know this. And this was my point - what's there now for any provider isn't set in stone. And since Cable's core network is fiber they are well poised to upgrade when the need arises. |

| Well, using your methods the current 4x1 bonding with 125 homes per node (conservative) nets you 1.216 Mbps per customer down, 240 kbps per customer up. Apple to apples, kthxbai.
Also, not all providers use PON. Active Ethernet systems are at 100 Mbps or 1 Gbps now. PON systems have more capacity overall but active has more non-blocking capacity, which is the game you want to play.
Oh, and for kicks, let's factor in cable not having 64QAM uploads in many areas (basically most non-Comcast territory). The result: 80 kbps of upload capacity per customer non-blocking in those areas (10 Mbps of upload capacity over 125 homes). |

why not just provision DSL modems faster? cant DSL do something like 16mbit or is that only if the DSLAM is in your celler.

Right now Verizon is the clear winner! No, not everything is going to be coming over DOCSIS 3.0. They have no reason to send HDTV or VOD over DOCSIS, because they already have video delivery systems that use the other bandwidth on the coax. There is no reason for cable providers to deliver IPTV over DOCSIS 3.0 since they have already paid for QAMs to deliver digital channels over analog. They MIGHT switch VOD to be delivered over DOCSIS 3.0, as that would save them some conversions and some hardware. But even if they had 1 DOCSIS 3.0 channel dedicated to VOD, and 2 or 3 dedicated to wideband Internet, they'd still have many more analog channels left to deliver many things on.
And really, you threw phone in there? VoIP takes about 150k, 300k if you have 2 lines going at the same. That isn't even something you'd worry about with DOCSIS1.1 much less 3.0.
FIOS FTTH carries the video product on different frequencies than the Internet product as well. So both FTTH and DOCSIS 3.0 are well positioned to provide plenty of Internet bandwidth.
They already easily deliver HD video and video on demand over fiber and coax.
And if anything, because of falling ad revenues and cable and content providers playing hardball over carriage, I see there being less TV channels in the future as less watched channels have to shut down, so bandwidth on that FTTH and coax isn't going to really be strained at all. |
