    A multi-layer next generation PON prototype has been built and tested, to show the feasibility of extended hybrid DWDM/TDM-XGPON FTTH networks with resilient optically-integrated ring-trees architecture, supporting broadband ...
  • Digitally processed modulation formats and integrated photonics for flexible optical metro-access networks 

    Lázaro Villa, José Antonio; Schrenk, Bernhard; Malligaraj, M.; Cano Valadéz, Iván Nicolás; Parra, M.; Sridharan, Madanagurusamy; Junyent Giralt, Gabriel (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report

    Digitally processed modulations formats such as Nyquist-WDM are investigated for implementation of future flexible optical networks, by using integrated photonic devices and moderate speed optoelectronics. We compare ...
  • Flexible WDM/FTDM passive optical network with RZ-seeded all-optical sub-wavelength grid engine 

    Schrenk, Bernhard; Katopodis, Vasilis; Bauwelinck, Johan; Lázaro Villa, José Antonio; Yin, Xin; Bakopoulos, Paraskevas; Spyropoulou, Maria; Qiu, Xing Z.; Avramopoulos, Hércules (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report
    Restricted access - publisher's policy
    All-optical FDM grid generation and channel selection is experimentally demonstrated through optical signal processing. Full-duplex 10G/2×10G transmission with reflective ONUs is validated for 20dB budget and 25km reach. ...
  • Quaternary TDM-PAM and its implications for TDMA equipment 

    Dris, Stefanos; Bauwelinck, Johan; Yin, Xin; Schrenk, Bernhard; Lázaro Villa, José Antonio; Katopodis, Vasilis; Bakopoulos, Paraskevas; Verbrugghe, Jochen; Avramopoulos, Hércules (2012)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • 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)
