Re: An advantage of FTTH is to end copper maintenance
Lines can be cut, but I will say POTS worked for 5 days while the power was out all over Orlando after the hurricanes. No "8 hour" crap. I think if Verizon gave a damn about their customers, they would have developed this in a way so that people not only could switch back to POTS, or another carrier, but they would also make it more reliable by providing power for the OTN thru their own copper. Never did I say it was a "guarantee" but I do know POTS has a higher uptime and reliability than FiOS, and thats because it's ran off the telco's own power stations (in most cases). I don't claim this is the case for EVERYONE, but if you're connected to the CO, and not an RT, I can guarantee the phone will work in a power outage unless a tree takes down your F1 or F2 pair, or your CO gets clobbered with falling trucks from a tornado...

It's such a waste to pull it all out... But it doesn't guarantee anything. Lines can be cut, telephone poles can be knocked over, etc. Just because you have a copper pair can't give you your warm and fuzzy feeling 24/7.
A UPS of some sorts that can provide backup telephone power for 6-8 hours will cover an overwhelming majority of all blackouts that typically occur. Will it cover all of them? No. But your copper-based POTS service also isn't guaranteed to be up during all prolonged outages either.
By maintaining a separate copper network for power distribution, you are just doubling the amount of lines that must be maintained, and they are of different technologies so they probably would be different crews. The power requirements for an ONT are also much higher. I believe the numbers are a few hundred milliwatts for POTS, 20+ watts for the ONT. With that in mind, the existing copper network would have to be significantly updated to handle the additional load.
Plus, pulling the wire isn't going to waste. Have you seen what copper prices have been lately? It can get recycled. Miles and miles of cable, even at 22 or 24 gauge, can bring in a huge chunk of change.

said by Dennis : Why can't you....I don't see why lifting the pair at the CO incures more costs? Because maintenance cost of copper is much higher then fiber and copper take up more space then fiber.
The issue is not your copper circuit circuit per se it is the ability to decommission outside copper plant once fiber becomes pervasive.
In urban area it means being able to remove copper from underground ducts to install fiber without having to dig up the streets.
