%0 Journal Article %T Performance analysis of 3G-UMTS WDM-RoF links %A Carlos Almeida %A Mario Lima %A Antonio Teixeira %J Optica Applicata %D 2010 %I %X In this paper, we analyze the impact of using directly modulated lasers and low cost optical amplifiers to propagate 3G-UMTS radio signals over fiber links. First, we perform a simulation study to identify the main impairments in such systems, and then complement the work with laboratory experiments in order to confirm the results and optimize our low cost radio over fiber system. %K radio over fiber (RoF) %K passive optical networks (PON) %K wavelength division multiplexing (WDM) %K UMTS %K SOA %U http://www.if.pwr.wroc.pl/~optappl/pdf/2010/no4/optappl_4004p773.pdf
