Abstract
An integrated radio-over-fiber(ROF) system with 60 GHz wireless mm-wave transmission by using optical carrier suppression(OCS) is proposed and experimentally demonstrated. A Mach-Zehnder single-arm intensity modulator(IM) is employed to generate 60 GHz millimeter-wave by OCS, and the 2.9-Gbit/s on-off keying(OOK) signal is modulated on mm-wave by using other IM. Then the downstream signal is transmitted from central office to base station by fiber link. In the base station, the mm-wave is detected by a high-speed optical/electrical(O/E) converter before it is amplified by an electrical amplifier and beamed by the antenna. The received wireless mm-wave is demodulated by coherent demodulate to retrieve the baseband signal. The experimental results show that the 58 GHz optical millimeter-wave will be generated by 29 GHz radio frequency resource, and 2.9 Gbit/s downstream and upstream data can be transmitted over 20 km in fiber, and 2.6 m wireless distance can be realized simultaneously.
