Interference suppression schemes for Radio over Fiber simultaneously transmitted with 10 Gbps On-Off Keying

Radio over Fiber (RoF) and 10 Gbps optical On-Off Keying (OOK) signal can be simultaneously transmitted by using the stochastic process of optical OOK as a carrier for the radio frequency (RF) signal. The theoretical analysis of the power spectrum and error vector magnitude (EVM) agree with experimental results. The experimental and theoretical results show that the OOK modulation interferes with the RF signal. In this paper, interference suppression schemes are proposed. The improvement in terms of EVM and dynamic range is discussed from theoretical analysis and computer simulation.
