摘要:The optically generated adjacent channel interference (O-ACI) issue in the wavelength-reuse multi-channel radio-over-fiber systems is first studied. It is generated by the re-modulation of a downlink optical signal, which is already modulated by the downlink microwave signal. A carrier amplitude-phase-control double sideband modulation is proposed and experimentally demonstrated to improve the O-ACI in such systems. By tuning the bias voltage of the main modulator of the dual parallel Mach-Zehnder modulator, the amplitude and phase of the optical carrier are controlled to improve the O-ACI. Experiments show that the O-ACI in wavelength-reuse multi-channel WIFI-over-fiber system is reduced for 8 dB and the power penalty due to the O-ACI is improved by at least 5 dB when EVM is 6%.
