  • Field-Trial of a high-budget, filterless, lambda-to-the-user, UDWDM-PON enabled by an innovative class of low-cost coherent transceivers 

    Presi, Marco; Artiglia, Massimo; Bottoni, Fabio; Cano Valadez, Iván Nicolás; Tabares Giraldo, Jeison; Velásquez Micolta, Juan Camilo; Ghasemi, Saeed; Polo Querol, Víctor; Chu Guang, Yong; Prat Gomà, Josep Joan (2017-09-01)
    Article
    Open Access
    We experimentally demonstrate an innovative ultradense wavelength division multiplexing (UDWDM) passive optical networks (PON) that implements the full ¿-to-the-user concept in a filterless distribution network. Key element ...
  • Hitless dynamic wavelength allocation in coherent WDM-PONs 

    Presi, Marco; Rannello, M.; Artiglia, Massimo; Tomkos, Ioannis; Cano Valadez, Iván Nicolás; Prat Gomà, Josep Joan; Ciaramella, Ernesto (2016)
    Conference lecture

    Advantages offered by coherent detection systems in access networks are not limited to the increase of power budget due to the superior sensitivity. Channel selectivity is another intriguing feature offered by coherent systems ...
  • Real-time coherent ONU for ¿-to-the-user based on fully analogue processing of OOK signals 

    Bottoni, Fqabio; Presi, Marco; Artiglia, Massimo; Prat Gomà, Josep Joan; Ciaramella, Ernesto (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Restricted access - publisher's policy
    Using fully-analogue and commercially available electronics, we realize a real-time coherent ONU receiver for Ultra-Dense WDM-PON based on intensity-modulated signals. The receiver also requires common photonic components ...
