Abstract

An overlaid technique utilizing DWDM channels for the capacity upgrade of already installed full-mesh CWDM AWG-STAR systems has been proposed and investigated experimentally. In the experiment, SOA transceivers were examined for simple and cost-effectiveness point of view, and it revealed the potential of over 10 km transmission. In the proposed configuration, relatively high total insertion losses resulted from additional AWGs for DWDM channels caused fewer margin for the loss budget. Our results suggested that SOAT with higher gain and saturation power, or receivers with much higher sensitivity should be important role for this configuration in order to achieve much longer transmission distance.
