Facebook has become a major investor in high-capacity fiber optic routes to move data traffic between its data centers, including both undersea cables and terrestrial routes. The company will now begin selling unused capacity to other companies, effectively entering the wholesale fiber business.

Facebook has created a subsidiary called Middle Mile Infrastructure that will sell excess capacity on two new fiber routes that company is building to provide direct high-speed connectivity between its data center campuses in Virginia, Ohio and North Carolina.

“We intend to allow third parties — including local and regional providers — to purchase excess capacity on our fiber,” said Kevin Salvadori, Director of Network Investments at Facebook. “This capacity could provide additional network infrastructure to existing and emerging providers, helping them extend service to many parts of the country, and particularly in underserved rural areas near our long-haul fiber builds.”
