The different ISPs etc in the city can sign contracts with the city and get access to the MUFN fiber network. The city owns the main fiber network and does repair/maintenance. The city can take ownership of any lateral you build where the conduit is 3" or more if they desire. Also, they can take it if they decide to use it to hook up traffic signals, etc. It's much more complicated than I've detailed but it's really a partnership with the city and ultimately they can take ownership of any fiber you build off it if it would benefit the city as a whole, while still allowing you access of course.
