UWB-over-Multimode-Fiber Technology for Short- Range Communication Networks

Ultra-wideband (UWB)-over-fiber is an attractive technique to extend the reach of UWB systems and to consolidate wireless personal access networks with fiber-to-thecustomer-premises (FTTCP). In this scenario, simple ways to generate UWB signals by photonic means is highly desired. Moreover, detection techniques of UWB signals that simplify the transceivers are of crucial importance. In this paper, we present experimental results for the photonic generation of UWB signals complying with the Federal Communication Committee (FCC) mask by using an uncooled distributed feedback laser (DFB). We also show examples of the use of digital signal processing (DSP) to assist the detection of UWB signal over multi-mode fiber links for short range communication networks.
