Josep M. Fabrega,M. Svaluto Moreolo,Laura Martin,A. Chiado Piat,Emilio Riccardi,Diego Roccato,Nicola Sambo,Filippo Cugini,Luca Poti,Shuangyi Yan,Emilio Hugues-Salas,Dimitra Simeonidou,Matthias Gunkel,Robert Palmer,S. Fedderwitz,Danish Rafique,Talha Rahman,Huug de Waardt,Antonio Napoli +18 more
TL;DR: This paper describes the problematic filter narrowing effect in the context of next-generation elastic optical networks, and investigates different transmission techniques and the penalty introduced by the filtering effect when considering Nyquist wavelength division multiplexing, single side-band direct-detection orthogonal frequency division multipleXing, and symbol-rate variable dual polarization quadrature amplitude modulation.
Journal ArticleDOI
Monitoring and Data Analytics for Optical Networking: Benefits, Architectures, and Use Cases
Luis Velasco,Mario Ruiz,Filippo Cugini,Ramon Casellas,A. Chiado Piat,O. Gonzlez,Andrew Lord,Antonio Napoli,Patricia Layec,Danish Rafique,Antonio D'Errico,Daniel L. King +11 more
TL;DR: The emerging requirements for optical network management automation, the capabilities of current optical systems, and the development and standardization status of data models and protocols are reviewed to facilitate automated network monitoring are reviewed.

Andrea Sgambelluri,Jose-Luis Izquierdo-Zaragoza,Alessio Giorgetti,Ll. Gifre,Luis Velasco,Francesco Paolucci,Nicola Sambo,Francesco Fresi,Piero Castoldi,A. Chiado Piat,Roberto Morro,Emilio Riccardi,Antonio D'Errico,Filippo Cugini +13 more
TL;DR: A first demonstration of ROADM White Box augmented with machine learning capabilities is demonstrated, which includes various level of disaggregation, NETCONF/YANG control, telemetry and spectrum-based advanced monitoring functionalities.
Proceedings ArticleDOI
Enabling low-cost high-volume production compatible terabit transceivers with up to 1.6 Tbps capacity and 100Gbps per lane PAM-4 modulation for intra-data center optical interconnects up to 2km: The TERIPHIC project approach
Panos Groumas,Christos Tsokos,David de Felipe,Ute Troppenz,Romain Hersent,Paraskevas Bakopoulos,B. Atias,J.-Y. Dupuy,A. Pagano,A. Chiado Piat,S. Kibben,Lefteris Gounaridis,Adam Raptakis,M. Seyfried,Martin Moehrle,Ch. Kouloumentas,Norbert Keil,Hercules Avramopoulos +17 more
TL;DR: A summary of the progress on the TERIPHIC transceiver modules concept, both at the component level and integration level is presented, and it is suggested that a polymer photonic platform as a host motherboard should be considered for the integration level.
Proceedings ArticleDOI
Applicability of a new generation of photonic devices in backbone network scenarios
TL;DR: The characteristics of the transponders and optical nodes developed by the QAMeleon project are presented and an example of application of these systems in an optical backbone is illustrated and scalability extends beyond 2030 with the use of nodes with a greater number of ports and with the possible use of C + L band systems.
