      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

      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 ...
