High Speed 40-Channel DWDM Radio Over Fiber (RoF) System

In a micro-cellular RoF network a fiber-fed distributed antenna system is established. Each remote antenna receives radio frequency signals and transmits them over optical fiber link up to a central station for signal processing. A RoF system can further be enhanced by incorporating the dense wavelength division multiplexing (DWDM) technique for bandwidth utilization and ultra high speed communication. The present work aims to present a model for such a RoF system that operates at a high speed while having huge capacity. After an extensive literature review over the topic it was concluded that there is still a long way to go as far as RoF systems are concerned. In the process of developing a system having huge capacity and more speed constraints such as channel spacing, inter-symbol interference and four-wave mixing effects have to be considered which proves to be a challenge.
