On this page is a collection of links to maps of US longhaul and intra-regional fiber networks. Maps are links to material on company websites wherever possible. Fiber may be owned or leased via long term IRU. To be on this list, a provider should provide intercity transport services between at least 5 states. I realize 5 is arbitrary, but at the moment it seems to be a reasonable number. Maps for pure metro and smaller regional providers will be collected on another page at some point.

Because these are links to external sites, they may get broken from time to time when pages are moved, updated, or simply deleted. This list will be maintained but I can do a better job if readers help out. So if you see a broken link please leave a comment or email the webmaster so I can fix it promptly. If you know of a network that should be here but has mysteriously slipped past my nets, please leave a comment - this is meant to be an inclusive list, not an exclusive one.
