    The migration towards a 20 Gb/s quaternary TDM-PAM passive optical network with chirped and non-linear optical transmitters is experimentally studied. We show that a loss budget of 27.3 dB is compatible together with a ...
  • Quaternary TDM-PAM as upgrade path of access PON beyond 10Gb/s 

    Verbrugghe, Jochen; Schrenk, Bernhard; Bauwelinck, Johan; Yin, Xin; Dris, Stefanos; Lázaro Villa, José Antonio; Katopodis, Vasilis; Bakopoulos, Paraskevas; Avramopoulos, Hércules (2012-12-10)
    Article
    Open Access
    A 20 Gb/s quaternary TDM-PAM passive optical network with chirped and non-linear optical transmitters is experimentally demonstrated. The migration from legacy TDM-PONs and the implications of using available 10 Gb/s ...
  • SOA/REAM as Vector Modulator for QAM Upstream 

    Schrenk, Bernhard; Fàbrega Sánchez, Josep Maria; Kazmierski, Christophe; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan (2011)
    Conference report
    Restricted access - publisher's policy
    Simultaneous encoding of information in the optical phase and amplitude for upstream transmission is demonstrated with an integrated SOA/REAM of small form factor. The crosstalk penalties between the QAM tributaries are ...
  • Test-bed functionality of the SARDANA hybrid NG-PON 

    Prat Gomà, Josep Joan; Polo Querol, Víctor; Lázaro Villa, José Antonio; Bonada, F.; López Pastor, Eduardo Tommy; Schrenk, Bernhard; Omella, M.; Saliou, F.; Le, Q.T.; Chanclou, P.; Leino, D.; Soila, R.; Spirou, S.; Costa, L.; Teixeira, A.; Tosi-Beleffi, G.M.; Klonidis, Dimitrios; Tomkos, Ioannis (2011)

    The tests with broadband multimedia services of the SARDANA multi-layer prototype prove the feasibility of scalable hybrid DWDM/TDM-PON FTTH networks with resilient optically-integrated ring-trees architecture.
  • Wavelength conversion towards Rayleigh backscattering tolerant PONs via four-wave mixing in SOA-based ONUs 

    Schrenk, Bernhard; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan (2010)
    Conference report
    Open Access
    Wavelength shifting in PONs with downstream signal remodulation is presented, allowing upstream transmission over trees with 25km feeder and 1:32 split with penalties <2dB, originally Rayleigh backscattering limited. ...
  • Wavelength-tuneable remote node for enhanced resilience and optimization of WDM access networks 

    Lázaro Villa, José Antonio; Bonada Bo, Francesc; Schrenk, Bernhard; Costa, Liliana; Teixeira, Marco Antonio; Chatzi, Sotiria; Klonidis, Dimitrios; Tomkos, Ioannis; Prat Gomà, Josep Joan (IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
    Conference report
    Restricted access - publisher's policy
    A remote node design with a wavelength tuneable optical add/drop element is presented and experimentally demonstrated for application in a resilient ring+tree access network architecture. The flexibility of the network ...
