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