Ignoring the fact that we haven't reached our limits with fiber yet ...
If you're talking broadband, I think it's pretty reasonable to suggest that
a fiber plant will last 20 years with minor maintenance just given the
history of how long we've used copper.
When its 2012 and you have people who are still on DSL with 768K
"broadband", it's nice to toss around the theory that technology moves fast
and that 20 years from now everyone will have Terabit to the home over
wireless, but I really don't see it. Back in the 90s I was sure everyone
would have 100M to the home by now.
The next major speed boost for broadband will be over fiber. And because
the bottleneck at that point becomes equipment, we'll continue to see a
healthy round of upgrades in speed over the same fiber plant.
If people got serious about FTTH, I think a _very_ optimistic timeline
would be something like:
2015 - First communities coming online, 100M to the home (probably Gigabit
line rate, but throttled).
2020 - Gigabit to the home starting to become common
2030 - Gigabit to the home "typical"
2035 - 10G to the home starting to become common
2040 - Newer optics require better fiber for back haul, minor upgrades to
middle-mile needed to push speeds.
2050 - People finally agree to invest in those upgrades after "suffering"
10 years of "only" 10G to the home.
