I assume from the comment they mean from one exchange location to another, but even then it’s not true. Those routes are _overbuilt_ precisely because of HFT so getting on dark fiber for that is cheaper than other backhaul fiber.

I’ve been out of HFT for a long time but when I was in it you could get onto the state of the art microwave networks between Chicago and the east coast for ~25k a month, which isn’t cheap but also not the biggest expense an HFT firm would have.
