Yeah, here in the US there are geographically tiny pockets in a few major cities that have actual fiber. Most of the country, including a shocking number of dense urban areas outside the east coast, has zero fiber penetration. Of our two telephone monopolies, one installed fiber for 10 years and quit (the East Coast one), and the other basically never installed fiber to the home.

So anyway, outside that lucky group we all use cable only because the alternative is, in many places, 6Mbps ADSL on aging and flaky copper wires. Or potentially 12Mbps… VDSL? AT&T branded that as U-Verse for a while. But basically they ceded the market to the cable companies.
