James Creek, PA | aerial fiber wonder if they are doing aerial fiber only because they don't want to do and have to retract their "fios digs up your yard" commericals... what if we have conduit to our house underground and it goes right to the node because that is also where our tap is at? we have to put an aerial in in a 100% UG neighborhood? | |

| Re: aerial fiber It might not be available to 100% underground neighborhoods, unless conduit and vaults are already there.
Aerial plants have huge cost advantages and are fairly easy to reconfigure as needed in the future.
The problems and cost of undergrounding nearly killed fios early on, and probably are a large part of them not continuing. | |

kudos:2 | The anon sources say that an aerial or UG node is usable, but they won't be burying fiber to the home. They might be willing to work with you if you've got nicely maintained conduit from point A to point B though. | |
|
 | | | Re: aerial fiber I don't see why they couldn't equip installers with a trench digger and conduit (other than up front cost of course.). It would require a utility survey before they could even install anything though. | |

kudos:2 | Re: aerial fiber You said it yourself: cost. For $300 per month plus a $500 install fee, you're lucky to be getting 30 Mbit MetroE, let alone 305. | |
|
| | | | | Re: aerial fiber Well remember, this is residential service, it's not like it needs to be 305Mbit/s constantly, that's how DOCSIS works. With DOCSIS you have 20-50 homes on a node with multiple channels all subscribed to services ranging from 1Mbit/s to 50Mbit/s. My ISP's DOCSIS 3 deployment is just a simple 4x1 (4 bonded downstream 1 non-bonded upstream channel. With two available upstream channels.) configuration which equates to 152/54Mbit/s per node. So considering they're offering 50Mbit/s down it's very unlikely that people are actually going to use it all, all the time.
Just like with LTE. Sprint as you know is deploying a 5x5Mhz LTE carrier and each sector even on their 3G network sits at about 100 customers or so. Those 100 customers are sharing 37/18Mbit/s.
I really don't think Comcast is going to have a problem profiting off of this at all, I believe they could charge $155/mo and still rake in cash. | |

| Re: aerial fiber ...except this isn't DOCSIS. It's a fiber line right into the node, which itself has fiber all the way to Comcast's core. So you're looking at 10G of capacity all the way up the chain once you hit the node, and well above 305M on the last few hundred feet. | |
|
| | | | | | | Re: aerial fiber What I'm saying is that they don't exactly need to invest tons of money in capacity at the core. It likely doesn't cost them much to offer 305Mbps. They already try to throttle people in their DOCSIS network. | |

In some markets I've been told that grapevine is still active (this may have been two years ago). In most it's completely untouched. They just tend to enforce caps instead of use things like grapevine anymore. | |

by the way QAM64 upstreams have a payload of 30Mbps if they are 6.4MHz wide not 27Mbps like you are calculating which is for QAM64 downstreams only. | |

The payload is about 27Mbps, payload being the actual capacity of the channel for data after overheads, meta data, etc. You can't just calculate symbol rate times bits per symbol for payload, that's the line data rate not the payload.

I don't think it would only be aerial fiber installs if they are saying within 1/3 mile of node. There is no way aerial is going to fly in a 100% underground neighborhood they are going to have to dig. My area has underground utilities and I would bet that if fiber were to come to my area they would use underground utilites. | |

I think threading conduit is somewhat more sophisticated than just redig everytime they want to run new wires.. that's just too expensive. Mechanical threaders that can be manipulated with cameras and be able to bend the front end of the threadline as necessary to accomodate the proper pathway are much preferable to digging up.. that's only if the threading screws something up..
