    • Data plane elements for optical performance monitoring agnostic to the modulation format for disaggregated optical networks 

      Fàbrega Sánchez, Josep Maria; Locatelli, Fabiano; Nadal Reixats, Laia; Christodoulopoulos, Konstantinos; Svaluto Moreolo, Michela; Spadaro, Salvatore (2020)
      Conference report
      Open Access
      In this paper, data plane alternatives for optical performance monitoring are presented as enablers to address the key challenges in disaggregated optical networks. In fact, a key element of the disaggregated networks is ...
    • Experimental demonstration of a machine learning-based in-band OSNR estimator from optical spectra 

      Locatelli, Fabiano; Christodoulopoulos, Konstantinos; Fàbrega, Josep Maria; Svaluto Moreolo, Michela; Nadal, Laia; Spadaro, Salvatore (2020)

      Channel spectral monitors are becoming a cost effective solution to improve the management, resiliency and efficiency of next generation optical transport networks. We experimentally demonstrate a ...
    • Filter features extraction from optical spectra 

      Locatelli, Fabiano; Christodoulopoulos, Kostantinos; Fàbrega Sánchez, Josep Maria; Svaluto Moreolo, Michela; Nadal Reixats, Laia; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Open Access
      We propose a method to estimate the central frequency and the bandwidth of optical filters, that relies on optical spectra captured with optical channel monitors at ROADM’s ingress port. We demonstrate for both features ...
    • Machine learning-based in-band OSNR estimation from optical spectra 

      Locatelli, Fabiano; Christodoulopoulos, Konstantinos; Svaluto Moreolo, Michela; Fàbrega, Josep Maria; Spadaro, Salvatore (2019-12-15)
      Article
      Open Access
      Measuring the optical signal to noise ratio (OSNR) at certain network points is essential for failure handling, for single connection but also global network optimization. Estimating OSNR is inherently difficult in dense ...
    • Spectral processing techniques for efficient monitoring in optical networks 

      Locatelli, Fabiano; Christodoulopoulos, Konstantinos; Svaluto Moreolo, Michela; Fàbrega Sánchez, Josep Maria; Nadal Reixats, Laia; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2021-07-01)
      Article
