I'm looking for any publicly available data on where optical fiber (for Internet connectivity) is physically laid across the US. While there are commercial services that sell some of this data, and some limited datasets for particular cities / areas / network providers are available, is there anything like a federal database for this? For instance, FCC maintains data for where antennas (for microwave communication, etc.) are located. Anything similar for fiber?
EDIT: I'm more interested in long-haul fiber (i.e. wide area / between cities, etc.) than in fiber-to-the-home data.
