Experimental demonstration of a downlink multi-channel Hybrid Fiber-Radio using digitized RF-over-fiber technique

We propose an efficient transmission scheme for Hybrid Fiber-Radio (HFR) system using a digitized RF-over-fiber (DRoF) technique, which can simplify frequency translation functions and supports multiple wireless services. We experimentally demonstrate a DRoF-HFR downlink for the transmission of GSM, UMTS and WiMAX services, with a minimum sampling rate of 50 MHz and an overall optical data rate of 400 Mb/s. Experimental results show that the amount of amplification required for the image at the desired wireless carrier frequency becomes significant when the image resides in the 20th or higher order Nyquist zone.
