Why the time is right.

Correct, but these were the routes built between the telcos on the level of MAN's and WAN's not all the way to corporate lan's and definitely not to the far more numerous (and potentially profitable) users at the home.

You are missing the main target of FTTP initiatives, it's to bring high bandwidth service to the home users and small businesses that haven't built out their own fiber based backbones yet. Traditional copper provides insufficient bandwidth for multiple high utility services like video, telephony and internet service as was detailed in the article.



>So, without content control, inexpensive >hardware and/or access why is fiber to the >consumer going to find a welcoming audience now?

Because the consumers at the home (as determined by the trend of increased purchases to broadband services via cable) are demanding it now. The costs will be amortized over time and if the analysis has been done properly by the telco's will result in profits.

Obsoleted? The reverse is true, DWDM (dense wave length division multiplexing) allows essentially unlimited bandwidth on a single fiber by using chrominance multiplexing or sending different data along the same fiber by shifting the color of the transmitted light, this provides excellent shielding against interference of the signals and allows the bandwidth of the fiber to be limited only by the number of discrete "colors" of light the DWDM mux can provide. This makes existing fiber indespensible to future expansion not obsolete in any way.

As stated before, the new fiber will not replace fiber that was laid before..it is exactly that "new" to the "last mile" to the home users and small businesses. This was long held as the impediment to "convergence" in the late 90's of digital communication technologies. Imagine a single fiber coming to your home that provides all video(tv,cable,videophone)and all audio (telephony,radio) traditional services as well as providing high speed internet service..this is what is promised (and will be delivered) thanks to the pending FTTP implementations. As more bandwidth is needed it can be allocated on demand by sending it on a new color down the same fiber, without relaying cable. (assuming DWDM switches are being used for provisioning at the central office which is almost certainly the case) Such enhancements are years away as current color fiber can provide bandwidth beyond the capabilities of the copper used by cable companies to provide their current broadband services.

>Not ready for prime time...imho

An analysis of the facts shows otherwise.
