Optical microwave up-conversion via phase modulation in 60GHz radio-over-fiber links

摘要

We have theoretically investigated the transmission performance of the optical microwave up-conversion link by using a phase modulator and a dispersive fiber (standard single mode fiber). A theoretical approach has lead to the evaluation of the influence of dispersion on the 60 GHz radio-over-fiber (ROF) links. According to our theoretically analysis, the data signals carried by optical millimeter (mm)-wave after transmission along fiber suffer not only from fading but also from the time shift of the code edges due to the fiber dispersive, which limits the transmission distance of the optical mm-wave signals. The simulation results agree well with our theoretical analysis.
