I believe just about all the cable systems have replaced their backbone with fiber to the neighborhood. When I was working, back in 2000, that was pretty common.
The thing to look out for with cable is that they can give you very high speed down (from the Internet to your computer) but the speed up (from your computer to the Internet) is often really limited. It has to do with the spectrum allocation on the cable - upstream doesn't have a lot of spectrum. Of course, my knowledge of cable systems is dated (I retired shortly after 2000) so they may have made some changes.
