Fiber-distributed telco is more robust (Score:4, Interesting)
It's to their advantage to build redundancy into their distribution system or face the consequences later.
In the case of fiber-based distribution systems, they use a redundant ring (where a signal has a guaranteed redundant path) around their service area to accomplish this. When someone digs a trench and knocks out the service to a single home, it's still possible to run to a neighbor's house and use their phone in an emergency, so the federal regulations don't require complete redundancy on that "last mile".
Therefore, fiber-based telco services are inherently more robust than telco over copper. Not to mention the advantage fiber has in its resistance to electrical/radio interference lightning.

Back in the late 70's, when AT&T was the One Bell System, an internal estimate of the cost to install just the fiber for fiber-to-the-home for the entire system was about $300B. Fiber is cheaper now, but labor is more expensive, and the process is labor-intensive. And a dollar doesn't go as far as it used to.
Many of the "households" served are going to be in high-density housing, ie, apartments and condos. The costs for doing wiring (fibering?) in those can range from almost nothing (vertical risers with lots of empty space) to a ridiculous amount per foot (eg, ripping open firewalls to run the fiber and then restoring things to meet city code).
Still, I'd bet that the job could be done for less than $10T if universal fiber was mandated :^) For me, a more realistic concern is that the number of people qualified to install fiber is rather limited, and getting the job done would take a LONG time even if you had the money.

You generally have to fusion-splice it for these applications. Fusion splicing requires special training, expensive equiment and expertise that simple coax does not. No more installation contractors whose "in" was ownership of a van and a $250 course.
You could conceivably run cable from the powered location out to subpanels and then run fiber from the home to the subpanels with jacks rather than splices. By sending out the installers with preterminated lengths in 50' increments and instructing them to coil the excess at the home, it could be done. But if the connectors get dirty, its toast, pulling preterminated fiber is significantly more difficult than pulling unterminated wire, and either way its several times as expensive as coax.
Coax has plenty of bandwidth. Do you have any idea how much bandwidth is available in 60 analog television channels? Any idea how little bandwidth it takes to make a phone call? With a rational combination of the various multiplexing techniques (FDM, TDM, CDM) and an upper bound around 100 for the number of customers served on a particular coax segment, you could easily accomodate enough bandwidth to play one DVD movie, multiple phone calls and high speed internet all at once in each home.
Add a second coaxial cable and you can triple the number served on a segment by moving the head-end transmissions to one cable and the subscriber transmissions to the other. But best of all: Joe in a truck can still install the service in a subscriber's home without costing the company a fortune.

So, the coaxial cable can carry 360 mhz / 0.008 mhz = 45,000 simutaneous telephone conversations assuming they use the 20-years obsolete FDM scheme. Modern transmission techniques like CDMA bump data capacity in the same bandwidth up by at least an order of magnitude.
So, we're talking about the equivalent of half a million telephone conversations for each coax loop, and each coax loop serves only a few hundred households.

Ok - Fusion splicing does take some more specialized equipment. But the cost of a splice is down to $25. Not that expensive.
> But if the connectors get dirty, its toast
No. If the connector gets dirty, you clean it. Normally people doing FTTH don't use pre-terminated cable. They have found it cheapest to run unterminated cable, and then fusion splice on terminations. You could also put terminations directly onto the fiber in the field, but that take more time so it is more expensive.
>Coax has plenty of bandwidth
Yes - it has a lot of bandwidth, BUT fiber has much much more.

Of course, it'd be simpler to just do pure Ethernet, but it might be an easier sell to the community if we could do DBS TV too. Just plug in your satellite receiver, call Dish Network with your credit card number, and vegitate to your heart's content. Maintenance shouldn't be too big a deal.
Being fiber, extending the network to neighboring communities shouldn't be too big a deal, if this grand delusion works in the first place.

Unfortunately, if you go wired and own your own fiber, you'd open yourself to cable regulation.

PON Standards (Score:1)
Marconi's stock is 20 cents, I wonder if this product will survive.
Anyway, there are may companies working on a standards-based PON. There is a group called FSAN (Full Services Access Network) with a Web site http://www.fsanet.net [fsanet.net] that describes the standards.
FSAN is working on an ATM-based PON (APON) which will compete for dominance with Ethernet-based PON (EPON). If you are interested in PON technology, you should focus on these techniques since the interoperability between equipment vendors will be based on these methods.
Check out the equipment from Quantum Bridge [quantumbridge.com] for active products that support a standards-based PON.

The fiber is run to new homes already installed with ethernet networks during the construction phase.
They now advertise 10 Megabit service, but early reports from customers indicated speeds much closer to synchronous 100 Mb. Apparently, the funny part was customers trying to test the speed. It required several simultaneous downloads because of the lack of 100 Mb offerings.
They have different digital packages, but phone, internet and 200 channel "cable" was reported at about 100 bucks/month. There is significant savings with bundled services. Where can I sign up?

these things could whack both Ameritech and Comcast in one shot.
Except that I believe Ameritech is currently testing a service that provides all this. They laid the wire in some cities over the past year, and tests are supposed to begin this summer.
A friend of mine asked a technician who was helping to lay the wire, and got this information. Further, the bandwith could come close to 50 megabit per house. No telling what would be for which service though.

Fiber is only slightly more expensive at this point than copper, and telecoms are scheduled to replace about 300,000 miles of copper this year alone. Furthermore, the upkeep of passive optical networks is less than copper due to no need for amplifiers and other electrics.
It took my cable company years and $$$$$$ to replace the splitters to go up to 1000 MHz so they could offer digital TV and internet access. And that was *just* the splitters in the outdoor enclosures. Imagine digging up or laying down new cable...(and it would be fiber so labour would be higher and cable would be more expensive)
The splitter wasn't the problem. The problem was rolling the truck. That is what cable and telecoms are truly concerned about, because a $2 splitter just doesn't compare to a $40 man hour and a truck. The idea that fiber is more exspensive to work with is quickly becoming a myth, and at the present time the added installation cost is almost immediately recouped from cheaper operating expenses. Can you imagine how much it cost to provide battery backed power to a remote amplifier station every couple of miles. A PON will span 30miles with no amplification.
Can anyone find anything resembling a price tag? I Looked over the website and the only refference to money that I could find was an "Investors" link, LOL!
Alcatel has been advertising to vendors (ie, the telecoms) that they can easily provide the "triple play" for less than what people are paying now and still have a 3 to 5 year recovery period.
Last I heard in IEEE journal a year ago, this kind of 1-fiber line to your house is more of what Ameritech and Comcast are going to use to thwack the telephone companies, and not vice versa.
Don't believe everything you read in IEEE then. Telecoms are testing PONs with plans to roll them out RSN. The big hurdle is regulatory (as usual). The FCC doesn't allow telecoms to send video. Hard to deliver a triple play that way. It is true that some of the cable companies are also looking at fiber, because it is cheaper than copper and coax has some realistic bandwidth limits. Once the fiber is in the ground, it doesn't react with water and can be upgraded with end equipment for pratically infinite bandwidth.
The real kicker right now is that the telecoms are running scared of the cable guys. ADSL can't deliver TV, phone and data. It just doesn't have enough bandwidth for the video. But the cable guys are getting into the phone business. This gives them a huge advantage. Once the FCC lets the big telecom guys sell video, watch for a huge rollout of PON systems.
Fiber is hard to work with.
Things. They are a changin'.
Coax has plenty of bandwidth.
And no one needs more than 640K of memory either.
Finally. This technology won't see much play. Telecoms won't pick it up until it complies with ITU G.983.2. Those guys just don't play with things that aren't based on a written standard because of the headaches involved with swithing vendors. The only company with a 983.2 compliant PON system is Alcatel (of ADSL fame). You might want to check them out for a system that you might actually see installed at some point in the future.
