A study of new technologies for switching of information in transparent optical networks


This research project includes the studies of new generation optical networks, focusing as interest points the node architectures, the algorithms for information switching and the topologies for metropolitan and access optical networks. The addition of new functionalities using technologies WDM/OCDM should be studied to comprise the new scenarios of transparent networks with simplicity, high capacity for carrying information, efficiency and low implementation costs. Due to the high costs demanded for experimental works in this area, initially is proposed a theoretical study based on analytical and simulation models, considering a complete performance analysis with the most important parameters related to the Quality of Service (QoS), including important parameters of the physical layer that imposes serious constraints to the quality of the signal WDM/OCDM, as PMD and MAI. The estimated period to conclude this project is two years and it is mainly supported on computational resources (software and hardware) and research human resources. (AU)
