Abstract:
A new, to our knowledge, architecture scheme for future optical access networks is proposed from the network operator's perspective. The scheme converges wavelength-division-multiplexing passive optical network (WDM-PON) and radio-over-fiber (RoF) technologies. An optical frequency comb (OFC) is adopted as the multi-carrier light source, by which the colorlessness of optical network units (ONUs) is achieved. Direct detection is employed for downlink transmission to further simplify the ONU structure and reduce costs. Converged access of residential and micro base-station (BS) services is enabled, with residential services flexibly deliverable via wired or wireless means. Wavelength reuse is adopted to enhance spectral efficiency. The feasibility of the proposed scheme is investigated through analytical and simulation studies. The findings are expected to provide useful references for the design and optimization of future access networks.
