Multiservice hybrid radio over fiber and baseband AWG-PON using CWDM and spectral periodicity of arrayed waveguide gratings

We present a novel configuration of an Arrayed Waveguide Grating Passive Optical Network (AWG-PON) capable of delivering, simultaneously fixed, switched and broadcast services, both in digital and in radio-over fiber format from the central office (CO) to the optical network units (ONUs) and vice-versa. Multiservice delivery is obtained by means of exploiting the spectral periodicity of the AWG response for each CO-ONU connection and by using coarse wavelength division multiplexed (CWDM) to deliver different services originated at the CO and destined to a given ONU. Experimental results have been provided showing the feasibility of delivering simultaneously digital baseband at different bit rates and wireless services at different spectral bands with high quality.
