The core activity of Pully4net SA is the planning, construction and operation of fiber-optic networks, particularly FTTH (Fiber to the Home) networks, in the Pully region and its surroundings. The company provides the infrastructure for the fiber-optic networks, but allows other telecommunications providers to offer their services over this infrastructure. Pully4net itself does not offer telecommunications services, but focuses on the operation and maintenance of the fiber-optic networks.
