Abstract

In this paper, a full-duplex radio over fiber system with high linearity is proposed. The system overcomes the influence of the third-order intermodulation distortion and the periodic power fading in the downlink. At the same time, wavelength reuse is used in the uplink, which simplifies the complexity of the base station. A full duplex radio over fiber system with high linearity is realized. The experimental results show that compared with the conventional system based on single Mach Zehnder modulator, the third-order intermodulation distortion in the downlink of the proposed system is obviously suppressed and the influence of fiber dispersion is overcome, the spurious free dynamic range of the system is improved by 17dB, and the constellation and error vector amplitude of broadband RF signal are improved significantly. In addition, the uplink can achieve stable wavelength reuse and modulation transmission.
