Maine Fiber Company, Inc. (MFC) is building a dark fiber network called the Three Ring Binder across the State of Maine to improve broadband access in areas of need. Much of this project is funded by the American Reconstruction and Reinvestment Act (ARRA). MFC provides fiber along the Three Ring Binder project on an open-access, non-discriminatory basis.

This means that any financially responsible entity may lease fiber along the route, including any institution customer, telecom carrier, or internet service provider.

This also means that all users will have access at the same pricing and substantially similar terms and conditions relative to their use of the network.

MFC files a tariff with the Maine Public Utilities Commission with prices for all to see, and they are prominently displayed, along with a route map, on the MFC website.
