Is this a relatively urban area, though? Generally, high speed coax networks these days consist of a relatively short, often shared stretch of coax, connecting back to a fibre-optic node. You’re looking at something like this: https://en.wikipedia.org/wiki/Hybrid_fiber-coaxial#/media/Fi...
If the premises served are low-density enough, you may be looking at only one or two per coax section, and at that point you’re probably cheaper just using fibre to the premises anyway.
