Re: Most users could care less about infrastructure type Removing a tap from the hardline certainly will take out everyone else downstream from that since the cable is physically disconnected. The last time Comcast came through here replacing all the taps the cable was up and down all day long and into the next day. Not sure you really understand how this all works, or you're just being coy.
FiOS is 1 to 32 just like patcat88 said, and cable hangs anywhere from 100 to 500 or more houses on a single HFC 'node'. That topology is bandwidth limited due to the severely asymmetrical nature of the HFC network. Fiber does not suffer from that limitation. Coming back to your statement above, one failed tap can indeed affect every customer downstream, which could number in the hundreds, because in most cases the hardline passes through the tap. A passive fiber splitter failure would take out a much smaller number of customers.
As for coaxial cable being "forgiving", well, you're entitled to your opinion. But I've never seen a fiber network cited for leakage or failing due to signal ingress from nearby transmitters. Yes, it depends on how well the maintenance is handled, but cable companies are notoriously bad at that. |

1 edit | I agree cable companies are horrible at maintaining their plant, and that is generally because of the attitude/pride the employees have of the network.
I guess it is the design of the cable network too. We can pull a tap and there is a secondary bypass, hard to explain, more like a main that goes around that tap. We can pull a tap, like a module, and plug in a new one. If the thing is completely corroded or damaged then it would need to be pulled off but like I said usually the bypass will keep the rest up. Also, if it is that bad, everything downstream of that tap already had problems to begin with.
Generally I have never seen more than 200 on a node. As far as how many are beyond a tap, maybe 30 max.
It is all about design. Unfortunately what the big guys end up with is a bunch of old crap mixed in with new crap and a lot of un-caring employees doing what they have to just to make it "work". Well this is not the norm of a small network which is what I am dealing with.

As a general rule, taps are not daisy chained like that. |

You'd be surprised. I've seen (first hand) nodes as small as 100 and as large as 1200. As someone mentioned, the designs and the actual builds run the gamut. Good operators are splitting nodes (physically and logically) like crazy right now getting everything tightened up and ready for FiOS and U-Verse. When they get to 200 homes/node, DOCSIS 3.0, Switched Digital Video and they get analog down to 70 channels, life will be very good indeed. Competition is a wonderful thing. |

As a general rule, they are here on this system. Which may go a long way to explain why it positively sucks.
Too bad cable didn't feel it was necessary to properly maintain outside plant and provide quality service until the competitive bite was put on their asses. |
