Abstract :
We demonstrate for the first time the full-duplex transmission of 25-GHz spacing dense wavelength-division multiplexing (DWDM) millimeter-wave-band radio-on-fiber (RoF) system using a supercontinuum (SC) light source and optical frequency interleaving technique. In the proposed scheme, filtering response of the arrayed waveguide gratings for demultiplexer and multiplexer is used for suppression of undesired optical sidebands. All the 25-GHz spacing SC modes are used for downlink transmission with photonic up-conversion. The uplink RoF signals are generated with photonic down-conversion from the reused downlink signals. The up- and downlinks 60-GHz-band 156-Mbps RoF signals were simultaneously transmitted over 25-km standard single-mode fibers with error-free and 0.5 dB power penalties
