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 ... -
Design and implementation of low complexity adaptive optical OFDM systems for software-defined transmission in elastic optical networks
Nadal Reixats, Laia (Universitat Politècnica de Catalunya, 2014-11-21)
Tesi
Accés obertDue to the increasing global IP traffic and the exponential growing demand for broadband services, optical networks are experimenting significant changes. Advanced modulation formats are being implemented at the Digital ... -
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 ... -
Low complexity PAPR reduction techniques for clipping and quantization noise mitigation in direct-detection O-OFDM systems
Nadal Reixats, Laia; Svaluto Moreolo, Michela; Fàbrega Sánchez, Josep Maria; Junyent Giralt, Gabriel (2014-06-01)
Article
Accés restringit per política de l'editorialWe present different distortionless peak-to-average power ratio (PAPR) reduction techniques that can be easily applied, without any symmetry restriction, in direct-detection (DD) optical orthogonal frequency division ... -
Performance analysis of optical OFDM transmission systems using PAPR mitigation techniques and alternative transforms
Nadal Reixats, Laia (Universitat Politècnica de Catalunya, 2012-04-25)
Projecte Final de Màster Oficial
Accés obert[ANGLÈS] Optical orthogonal division multiplexing (OFDM) has recently been introduced in optical communications because of its robustness against channel dispersion and its high spectral efficiency. OFDM is based on the ... -
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 ...
