A Vision Towards F5G Advanced and F6G

F5G advanced and F6G optical networks require a change in thinking due to the growing integration of physical and digital worlds. With increasing digitalization of more and more aspects of our work, life, and society, new opportunities arise. Our future infrastructure needs to pave the way towards a digitized and intelligent society – with features towards a new way of perceiving the world and new communication paradigms between humans, machines, and the physical world. In this paper, we show the methodology of ETSI ISG F5G to advance technology in a use-case driven and roadmap-based approach. To illustrate this approach, we show a few example use cases that a future optical communication infrastructure needs to support. Such use cases will support the development of the roadmap for F5G Advanced and F6G, consolidating and coordinating the different technology trends to support our vision of bringing digital to every person, home, and organization for a fully connected, intelligent world.
