Re: Cable a FTTH
1. This is not the cable companies doing it, this is just Motorola marketing say "Hey you guys if you want to throw oodles of money at us for almost no benefit at the moment feel free"
2. I don't see cable companies doing any widespread FTTH push for at LEAST 5-7 years probably longer.
3. This one is more of a question but why is everyone so convinced coax is dead when it still has legs and can still be competitive for at least another 10-15 years.
benefits of fiber with the cable industry would not be seen for a long time...with the phone industry it makes since seeing as their current networks are so poor.

In order to have true IPTV and other new services that won't really work (like on-demand movies (a la AppleTV) to the home in HD and with the title breadth of a local Blockbuster) we're going to need 100-200mbps to the home. While copper from the curb could certainly handle this, it couldn't do it from the neighborhood with today's technology. And if you're going to pull fiber to the curb, you might as well go ahead and pull it all the way to the home. |

That is just marketing spam from Motorola 'give us money and we promise it will be cheaper in the long run'...
and to the rest of your post even if you despise SDV as a hack it is still not needed...it has great benefits yes, but the dropping of all analogues is where the bandwidth is really going to be coming from...

Yep, when cable drops the analog channels there will be plenty of bandwidth. I agree with you Loker, I don't see where the cable companies need to upgrade to fiber in the next 10-15 years. |

The coaxial can handle this. Heck cablevision is testing it now with the narad tech. IF narad can do it then docsis 3 can certainly do it all so.
The cable companies dont have to switch to ftth yet. |

I don't think they need to bring fiber all the way to the home in order to accomplish what they want. Coax, unlike twisted pair, has a TON of capacity potential. They just need to push fiber closer to the tap and make it operate more like a switched network. Even using today's QAM256 standard, that's 36mbps per 6mhz channel. If they allocate 800mhz of spectrum that's 133 channels. 133 * 36 = 4788mbps. Of course, that's not even the full potential. Some stacked satellite installs push data up to 2000mhz down RG6 coax.
The "problem" with existing cable networks isn't the capacity of the copper, it's that the vast majority of the available capacity is being consumed by broadcast data. SDV doesn't strike me as a hack, it's really more like the first evolutionary step towards making cable behave like a switched network.
The advantage in leaving the last leg in coax is you don't need to rewire homes and MDUs. Not terribly unlike how the fios ONT takes the fiber from the NID and goes copper to the rest of the home. A cable company looking to emulate FIOS could simply put the "fiber termination device" in the tap.
