Optical access networks to support future 5G and 6G mobile networks [Invited]

Abstract

This article presents an extended version of the ECOC 2024 invited paper on future converged fixed/mobile access networks in the 6G era. First, we outline the expectations for 6G from the perspective of a European operator, and then explore the potential optical network solutions that will support the future evolution of mobile networks. We identify key factors such as enhanced connectivity, efficiency, and flexibility, which will be enabled by technologies including AI, edge computing, HS-PON/PtP, VHS-PON/PtP, all-photonic networks, extended CTI, Open RAN, and other emerging features.
