Promising optical technologies for implementing F5G advanced networks

In 2020, the fifth-generation fixed network research group ETSI ISG F5G published technical specifications to define fixed network generations F1G-F5G, similar to mobile network generations. The working materials of this group identified the basic principles for the implementation of fixed-line networks that should appear in the near future. Recently, a number of additions and extensions to F5G concept have been proposed, which have received the collective name F5G Advanced. The article presents an analysis of the main directions of development of F5G Advanced networks based on new optical technologies in the future by 2030.
