actually, it says:
"
a.. Fiber technology provides nearly unlimited bandwidth,
a.. as much as 20 times faster than today’s fastest
a.. high-speed data connections."

which is pretty nondescriptive.
around here, that'd be 400 Mbs, not bad, but rather underutilizing
fiber capacity. 4 Mbs satellite up/downstreams i've seen are pretty
good for normal quality tv channels, HD done the right way is some
20 to 30 Mbs, so no way you can have many HD channels on a 400 Mbs
capacity link

some problems with ftth rollout:

world fiber production capacity being where it is, just to facilitate the US
alone would take decades of production

the associated cost is not equipment, nor fiber cost, it's the digging that
is extremely costly - it'll have to be paid for in some way to make ftth viable
