You can get on the poles, if they're there and there's room, and you can find and follow the attachment rules and pay the attachment prices. Back when Google was going to run fiber to the home, they couldn't figure out how to manage the rules, which made their deployments very slow and eventually they gave up when AT&T (and others) deployed fiber to the communities Google announced before Google had managed to get plans finished.

They probably should have found a small telco or three to buy for expertise on pole bureaucracy.

Responding to your parent...

> You can probably lease a connection to the fiber network in the same way (I haven't checked, but I assume common carrier applies), but if there's no fiber to the addresses you want to service you're SOL unless you want to front tens of thousands of dollars per customer. No ROI on that for many, many years.

I would assume mandatory line sharing doesn't apply; the FCC walked back almost all of the 1996 Telecom Act line sharing; telcos and cablecos may well have designed their fiber to the home in ways to thwart what limited regulation was present anyway. If you're near 'commercial' fiber though, lots of that is available for lease.
