one of the reasons why free space optics gigabit and 10GbE ethernet laser based links are a tiny niche product in the ISP space, millimeter wave (71-86 GHz) fills the purpose much better.

also they don't do as well in rain as something that can adapt modulation.

Yeah, that is likely why terrestrial FSO seems to be mostly dead these days as far as I can tell. Even back then there used to be a backup RF link in case of fog - why not have a proper RF link instead, especially if its going to be much better due to all the money dumped into RF technology in comparison to free space optics.
