I have FIOS in my condo.  Fiber comes up to the building, then is bridged into the telephone line using VDSL.  Once inside, Verizon provides both a VDSL modem, and a wireless router (the two are connected by a CAT5 cable.)  From there, I installed a 16 port gigabit switch and a N access point.  I get 20/5 Gb service consistently.  Runs $60/month, with like a $15 discount if you bundle with FIOS TV, which I do. I could get 20/20 Gb, but that is not offered as part of a bundle.
