I should probably have mentioned that in this sense I view “urban” as exclusive to “single family homes” - meaning I’m talking about high density modern urban with under grounding requirements - and high rise residential towers.

We are the opposite, we are presently enterprise, midsize, and exotic-small business only, and have no residential arm or support structure (or SLA expectations, or standards or lack thereof) of a residential connection.

The backbone in a sub area is typically build with a 24 fiber strand cable. Because fibers are not free and are actually quite expensive as the number of fibers grow and the distances get longer. We can do a few point to point connections, for example if we need to deliver a commercial service or for our own needs (to connect POPs etc).
