      Vall-llosera, Gema; Rafel, Albert; Ciaramella, Ernesto; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Restricted access - publisher's policy
      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)
      Conference report
      Restricted access - publisher's policy
      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)
      Conference report
      Open Access
      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 ...

    • Technologies for cost-effective udWDM-PONs 

      Prat Gomà, Josep Joan; Cano Valadez, Iván Nicolás; Presi, Marco; Tomkos, Ioannis; Klonidis, Dimitrios; Vall-llosera, Gema; Brenot, Romain; Pous, R.; Papastergiou, george; Rafel, Albert; Ciaramella, Ernesto (2016-01-15)
      Article
      Open Access
      New technologies for ultradense WDM-PON (udWDM-PON), enabled by coherent techniques and low-cost devices, are developed for an efficient utilization of the optical spectrum, revealing that the “Wavelength-to-the-User” ...
