      Five basic requirements have been defined for the COCONUT ultra-dense WDM PON architecture: (1) untouched optical distribution network, (2) no active components, (3) no intervention in the outside plan, (4) smooth upgrade ...

    • Control and management requirements for a coherent ultra-dense WDM PON for lambda to the user access networks 

      Ververidis, Christopher; Tomkos, Ioannis; Klonidis, Dimitrios; Rafel, Albert; Parkin, Neil; Urban, Patryk; Prat Gomà, Josep Joan; Segarra Mullerat, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper we first highlight the arising MAC-layer requirements for a coherent ultra-dense WDM PON for full and shared lambda to the user access networks. We then report on the appropriate modifications of the XGPON ...

    • Cross-connection management specialisation for WDM-OTN's 

      Rafel, Albert; Comellas Colomé, Jaume; Junyent Giralt, Gabriel; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2000)
      Text en actes de congrés
      Accés obert
      WDM optical transport networks (WDM-OTN) will use new all-optical nodes that will perform functions in the optical domain, using wavelength as a new network resource. This paper presents a new approach for the optical ...

    • Network traffic analysis under emerging beyond-5G scenarios for multi-band optical technology adoption 

      Ruiz Ramírez, Marc; Hernández Gutiérrez, José Alberto; Quagliotti, Marco; Hugues Salas, Emilio; Riccardi, Emilio; Rafel, Albert; Velasco Esteban, Luis Domingo; González de Dios, Oscar (Optical Society of American (OSA), 2023)
