description

In this paper, a scheme for multiplexing millimeter-wave carriers on a single optical carrier and using an all-optical millimeter-wave demultiplexer is presented. The optical demultiplexing of radio-over-fiber signals is based on dual sideband modulation with suppressed optical carrier combined with the filtering properties of dual over-written fiber Bragg gratings. The performance of the system is investigated using a single optical carrier and independent data modulated millimeter-wave signals at 20 and 40 GHz. The signals are transmitted over optical fiber, demultiplexed and wirelessly distributed to a mobile unit. It is found that performance of the demultiplexing using fiber Bragg gratings gives less than ?40 dB electrical power interchannel crosstalk and the spurious free dynamic range is measured to be 80 dB. Hz2/3. Furthermore, PSK, QAM and ASK PRBS modulated data up to 2.5 Gb/s are successfully transmitted through the wireless link.
