      We theoretically investigate and experimentally demonstrate a scheme for all-optical carrier recovery in loopback access networks that avoids orthogonal or complex modulation formats for the downstream or upstream signals. ...

    • 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)

      Accés restringit per política de l'editorial
      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. ...

    • Full-duplex 20/10 Gb/s WDM-PON with remodulation of chirped ASK and multi-level quaternary PAM and OFDM 

      Lázaro Villa, José Antonio; Bernhard, Schrenk; Maziotis, Alexandros; Cano Valadéz, Iván Nicolás; Bakopoulos, Paraskevas; Prat Gomà, Josep Joan; Avramopoulos, Hércules (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A full-duplex 20/10Gb/s WDM-PON is demonstrated by all-optical carrier recovery technique, showing that it is efficient and flexible for being applied to different downstream signals as non-/chirped ASK or multilevel signals ...

    • 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)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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
      Accés obert
      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 ...
