      In this paper, we motivate a brown-field migrationplanning as a cost-efficient procedure to scale the capacity ofshort-term realizable elastic optical networks (EONs), graduallyconverting them into ...
    • Greenfield gradual migration planning toward spectrally-spatially flexible optical networks 

      Lechowicz, Piotr; Goscien, Roza; Rumipamba Zambrano, Rubén Darío; Perelló Muntan, Jordi; Spadaro, Salvatore; Walkowiak, Krzysztof (2019-10-01)
      Article
      Open Access
      This article identifies the unavoidably required upgrade of short-term realizable elastic optical networks (EONs) operating over single-mode fibers toward spectrally-spatially flexible optical networks (SS-FONs), exploiting ...
    • Inter-core crosstalk impact on migration planning from elastic optical networks to spectrally-spatially flexible optical networks 

      Lechowicz, Piotr; Rumipamba Zambrano, Rubén Darío; Perelló Muntan, Jordi; Spadaro, Salvatore; Walkowiak, Krzysztof (Optical Society of American (OSA), 2019)
      Conference report
      Open Access
      We study inter-core crosstalk (ICXT) impact on migration planning toward spectrally-spatially flexible optical networks considering 22-core multi-core fiber. Results reveal that 55-70% of links need to be upgraded when ...
    • Migration planning from elastic optical networks to spectrally-spatially flexible optical networks 

      Lechowicz, Piotr; Rumipamba Zambrano, Rubén Darío; Perelló Muntan, Jordi; Spadaro, Salvatore; Walkowiak, Krzysztof (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Open Access
      We focus on a migration planning from elastic to spectrally-spatially flexible optical networks by upgrading regular with SDM-capable ROADMs. Our most promising strategy reveals that by migrating 30% of the regular ROADMs ...
