why not use the co-ax thats already running to each apt since i know they use that for a lot of installs now run the fiber in to the basement or were ever the co-ax comes in at
Most of the apartment buildings (at least here in NYC) do not have a home-run of coax from each apartment to the basement, they have feeders going up to closets on each floor and distribute the signal from there. Also, while the coax would work fine for video & Internet, the FIOS equipment cannot use coax for dialtone.
