      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.

    • Time interleaved DPSK/ASK transmitter with directly beat modulated DFB for coherent WDM-PON

      We experimentally demonstrate a novel low-cost 2.5 Gb/s/¿ transmitter based on a directly modulated DFB laser featuring DPSK/ASK interleaved in time. Rx sensitivity of -44 dBm is achieved at BER=4· 10-3 with 2 dB improvement ...

    • UDWDM-PON using low-cost coherent transceivers with limited tunability and heuristic DWA 

      Sales Zaragozá, Vicente; Segarra Mullerat, Josep; Polo Querol, Víctor; Velásquez Micolta, Juan Camilo; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2016-08-01)
      Article
      Accés obert
      A new Passive Optical Network (PON) for access, making use of Ultra Dense Wavelength Division Multiplexing (UDWDM) by densely spacing channels at few GHz, and introducing the “wavelength-to-the-user” concept, is proposed. ...

    • Viability of in-service, low-cost and spatially unambiguous OTDR monitoring in TDM- and WDM-PON access networks 

      Lázaro Villa, José Antonio; Polo Querol, Víctor; Costa, L.; Teixeira, A. (IEEE Press. Institute of Electrical and Electronics Engineers, 2009-06-28)
      Comunicació de congrés
      Accés obert
      A new strategy is proposed to efficiently monitor fibre plant failures in current and future optical access networks by implementing an OTDR subsystem in the physical layer. The viability of the method is evaluated ...
