Broadband access services in the era of 5G and beyond are driving the evolution of optical access networks from a fiber-to-the-home/ fiber-to-the-building infrastructure to a more common access platform, compatible with both wired and wireless broadband services. Accordingly, a flexible optical access network plays a pivotal role in catering to various service requirements. This work proposes a reconfigurable converged optical fronthaul network for wireless and wired services using a 4◊4 microring resonator (MRR) based silicon photonic (SiP) switch fabric. Reconfigurable service selection is demonstrated for wavelength selective, multicast and space switching scenarios. The reconfiguration of digital data and digital radio-over-fiber (DRoF) services for cloud radio access networks (C-RAN) is demonstrated.
