A 5G mmWave Fiber-Wireless IFoF Analog Mobile Fronthaul Link With up to 24-Gb/s Multiband Wireless Capacity
N. Argyris,G. Giannoulis,Konstantina Kanta,Nikolaos Iliadis,Christos Vagionas,S. Papaioannou,George Kalfas,Dimitrios Apostolopoulos,Christophe Caillaud,Helene Debregeas,Nikos Pleros,Hercules Avramopoulos +11 more
TL;DR: It is shown that by replacing the stand-alone optical modulator with an InP-based externally modulated laser chip for the implementation of the IFoF transmitter, a 16-Gb/s aggregate capacity was showcased on a 7-km fiber link and 5-m wireless channel with a 4-band 16-QAM encoded at 1 Gbaud.

ORCHESTRA - Optical performance monitoring enabling flexible networking
Konstantinos Christodoulopoulos,Panagiotis Kokkinos,A. Di Giglio,A. Pagano,N. Argyris,Christos Spatharakis,Stefanos Dris,Hercules Avramopoulos,J.-C. Antona,Camille Delezoide,P. Jenneve,Jelena Pesic,Yvan Pointurier,Nicola Sambo,Filippo Cugini,Piero Castoldi,Giacomo Bernini,Gino Carrozzo,Emmanouel Varvarigos +18 more
TL;DR: The ORCHESTRA vision is to close the control loop, enabling true network dynamicity and unprecedented network capacity efficiency.
Journal ArticleDOI
Toward efficient, reliable, and autonomous optical networks: the ORCHESTRA solution [Invited]
Kostas Christodoulopoulos,Camille Delezoide,Nicola Sambo,A. Kretsis,Ippokratis Sartzetakis,Andrea Sgambelluri,N. Argyris,Giannis Kanakis,Pietro G. Giardina,Giacomo Bernini,Diego Roccato,A. Percelsi,Roberto Morro,Hercules Avramopoulos,Piero Castoldi,Patricia Layec,Sebastien Bigo +16 more
TL;DR: The ORCHESTRA network makes use of coherent optical transponders as software-defined optical performance monitors (soft-OPMs) to improve the optical network observability and closes the observe–decide–act control loop, automating the mechanisms required to trade efficiency for reliability.
Journal ArticleDOI
Marginless Operation of Optical Networks
Camille Delezoide,Kostas Christodoulopoulos,A. Kretsis,N. Argyris,Giannis Kanakis,Andrea Sgambelluri,Nicola Sambo,Pietro G. Giardina,Giacomo Bernini,Diego Roccato,A. Percelsi,Roberto Morro,Hercules Avramopoulos,Emmanuel Varvarigos,Piero Castoldi,Patricia Layec,Sebastien Bigo +16 more
TL;DR: This work experimentally demonstrate the ability of the ORCHESTRA solution for early detection and localization of failures, to preventively mitigate their impact, and thus guarantee smooth network operation and demonstrates a fully automated reconfiguration of marginless connections undergoing critical performance variations over 228 km of field-deployed fiber.
Proceedings ArticleDOI
Analog Radio-over-Fiber Solutions for 5G Communications in the Beyond-CPRI Era
Giannis Giannoulis,N. Argyris,Nikos Iliadis,Giannis Poulopoulos,Konstantina Kanta,Dimitrios Apostolopoulos,Hercules Avramopoulos +6 more
TL;DR: This paper aims to explore the role of Analog RoF solutions moving beyond CPRI implementations for future 5G architectures, highlighting the impact of digital-signal-processing to proposed network implementations.
