Tesis doctoral de Carles Bock Montero
This thesis presents an upgrade path from the existing copper-based access networks to a second-generation fiber-to-the-home approach based on advanced wavelength-routed passive optical networks. the upgrade path is presented in two stages, which deploy fiber from the central office to the end users in a gradual manner, offering also incremental bandwidth to the user when the fiber is nearer the end customers. when the upgrade path is totally deployed and fiber is present in the entire link between the central office and the end users, several advanced topologies are presented as candidates for second-generation access networks. All of them are based on advanced wavelength routing profiles and combined wavelength / time multiplexing techniques. these advanced topologies, together with the use of tunable sources at the central office allow the implementation of an advanced media access control protocol that can assign bandwidth on demand to different geographic locations in real time depending on the network utilization. laboratory testbeds have been implemented to corroborate optical connectivity and correct data transmission in order to verify the feasibility of the upgrade paths and advanced topologies. additionally, mathematical models and networks simulations have been developed to corroborate and measure the improvements on network performance of the proposed media access control protocol in comparison with the existing protocols for commercial passive optical networks.
