Comparison of the three schemes to generate optical mm-wave signal and wavelength reuse for upstream connection in the radio-over-fiber systems

Three different schemes to generate optical millimeter-wave and wavelength reuse for up-link connection in the radioover- fiber (ROF) systems have been theoretically and experimentally investigated. We have compared the performance of the three different schemes for the radio-over-fiber systems considering the cost and configuration of their architectures. A novel scheme to generate optical millimeter-wave and realize centralize lightwave operation in the radio-over-fiber (ROF) systems has been demonstrated. This scheme has shown high performance and low cost compared with the existing schemes.
