The benefits of superfast broadband are well established, but the best way of installing the fibre is still being debated. Established models range from fully government-owned fibre, through to fully privatised models that rely on service providers to get services up and running. Choosing the right model, and rolling out fibre deployments effectively using the chosen model, is a task that varies with geography, subscriber density, demand, and the willingness of telecommunications companies and government to invest in the backbone of the optical communications network.
