Broadband in America from an insider.

We started a few years ago of not placing any new copper to greenfileds. New Mdu/mtu house services such as alarms and elevators are on fiber as well. We just have to supply the initial battery at install. We have been doing CLECs on our fiber for several years.
As for SFU greenfields, if the developer doesn't want us to place fiber for some reason, we simply don't go in.
