Fast, reliable and everywhere are the qualifiers for access to information. Therefore to provide both high capacity and flexibility, the transport of wireless and wireline signals is converging into a common telecommunication infrastructure. In this project, we focus on the study of wavelength-division-multiplexing (WDM) optical phase modulated radio-over-fiber (RoF) system, which is a promising solution to implement broadband seamless wireless-wireline access networks. One important feature of phase modulated, radio-over-fiber systems, is their robust transmission, high spectral efficiency and high dynamic range properties, not achievable by conventional intensity modulated systems. However, to the best of our knowledge, no comprehensive theoretical and/or experimental study of the performance of these WDM RoF systems has been reported yet. Furthermore, the stringent requirements of future communications links in terms of capacity, flexibility and multi-service support, motivate us to undertake a concise assessment of the ultimate achievable performance of wireline/wireless converged systems. The goal of this project is to theoretically and experimentally investigate the performance of multi-channel phase modulated radio-over-fiber optical links for the transmission wireless and wireline signals. The timely generated knowledge in this project will contribute to extend the state-of-the-art and to enhance European research excellence and competitiveness in developing solutions for future telecommunication networks.
