In 2018, the City of Centennial completed construction of a 432-fiber strand backbone that connects key City sites and provides opportunities for community anchor institutions.

The completion of the backbone also enables both existing and new broadband providers to tie into the new infrastructure with the goal of providing better and more competitive choices and services for the City's residents.

Centennial FiberWorks Schedule of Rates

The City of Centennial's FiberWorks initiative is offering dark fiber leases on its 50-mile fiber network for the City’s businesses, Internet service providers (ISPs), community anchor institutions and government entities. Centennial has already executed multiple dark fiber leases ranging from one year to 20 years and is looking to further utilize its network through dark fiber leases in the community. Centennial is offering flexible lease options suited to the needs of our community members and is able to expand the network to underserved areas.
