    • Autonomous and energy efficient lightpath operation based on digital subcarrier multiplexing 

      Velasco Esteban, Luis Domingo; Barzegar, Sima; Sequeira, Diogo Gonçalo; Ferrari, Alessio; Costa, Nelson; Curri, Vittorio; Pedro, João; Napoli, Antonio; Ruiz Ramírez, Marc (2021-09)
      Open Access
      The massive deployment of 5G and beyond will require high capacity and low latency connectivity services, so network operators will have either to overprovision capacity in their transport networks or to upgrade the optical ...
    • Soft-failure localization and device working parameters estimation in disaggregated scenarios 

      Barzegar, Sima; Virgillito, E.; Ruiz Ramírez, Marc; Ferrari, A.; Napoli, Antonio; Curri, Vittorio; Velasco Esteban, Luis Domingo (2020)
      Conference report
      Restricted access - publisher's policy
      A soft-failure localization and key working parameters estimation system is proposed for network diagnosis and maintenance. We show that a double analysis of monitoring data and estimated working parameters ...
    • Square-root strategy: a novel method to linearize an optical communication system with electronic equalizers 

      Prat Gomà, Josep Joan; Napoli, Antonio; Gené Bernaus, Joan M.; Omella Cáncer, Mireia Esther; Poggiolini, P.; Curri, Vittorio (2005)
