You could imagine commercial/institutional sites hundreds to thousands of miles apart with <10ms latency on dedicated fiber.


Wouldn’t that be way faster than the speed of light?


Depends how many thousands ;) light travels about 3000km in 10ms

That’s in a vacuum, in a straight line. In fibre optic cable, light travels around two thirds of that speed.
