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)
Text en actes de congrés
Accés obertIn 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)
Text en actes de congrés
Accés restringit per política de l'editorialChannel 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, Konstantinos; Fàbrega Sánchez, Josep Maria; Svaluto Moreolo, Michela; Nadal Reixats, Laia; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2020)
Text en actes de congrés
Accés obertWe 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
Accés obertMeasuring 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
Accés obertHaving ubiquitous optical monitors in dense wavelength-division multiplexing (DWDM) or flex-grid networks allows the estimation in real time of crucial parameters. Such monitoring would be even more important in disaggregated ... -
Study and application of spectral monitoring techniques for optical network optimization
Locatelli, Fabiano (Universitat Politècnica de Catalunya, 2021-11-18)
Tesi
Accés obertOne of the possible ways to address the constantly increasing amount of heterogeneous and variable internet traffic is the evolution of the current optical networks towards a more flexible, open, and disaggregated paradigm. ...
