Experimental Demonstration of Extended 5G Digital Fronthaul Over a Partially-Disaggregated WDM/SDM Network

Fabrega, Josep M.; Múñoz, Raúl; Nadal, Laia; Manso, Carlos; Svaluto Moreolo, Michela; Vilalta, Ricard; Martínez, Ricardo; Vílchez, Francisco Javier; Pérez-Galacho, Diego; Sales Maicas, Salvador; Grivas, Evangelos; Turkiewicz, Jaroslaw P.; Rommel, Simon; Tafur Monroy, Idelfonso (Institute of Electrical and Electronics Engineers, 2021-09)

[EN] We experimentally demonstrate a 5G digital fronthaul network that relies on multi-adaptive bandwidth/bitrate variable transceivers (BVTs) and an autonomic software-defined networking (SDN) control system for ...
On N-PAM and M-QAM implementation within the hybrid RoF-FSO-PON system

Nguyen, Dong-Nhat; Zvanovec, Stanislav; Bohata, Jan; Ortega Tamarit, Beatriz; Vallejo-Castro, Luis; Ghassemlooy, Zabih (IEEE, 2020-11-25)

[EN] This paper investigates an optical transmission architecture of a passive optical network (PON), which is compatible with the millimeter-wave radio-over-fiber and free-space optics systems (RoF-FSO) under weak-to-strong ...
Performance Comparison of OFDM-UWB Radio Signals Distribution in Long-Reach PONs Using Mach-Zehnder and Linearized Modulators

Alves, Tiago; Morant, Maria; Cartaxo, Adolfo; Llorente, Roberto (Institute of Electrical and Electronics Engineers (IEEE), 2011-06)

[EN] The performance of orthogonal frequency division multiplexing ultra wideband (UWB) radio signals distribution in long-reach passive optical networks (LR-PONs) using conventional chirp-less Mach Zehnder (MZ) and ...
Transmission of 2 bits/symbol over RoF and RoFSO links with different architectures for ubiquitous coverage

Nguyen, Dong-Nhat; Zvanovec, Stanislav; Vallejo-Castro, Luis; Ortega Tamarit, Beatriz; Bohata, Jan; Ghassemlooy, Zabih (IEEE, 2020-07-22)

[EN] This paper investigates integrated radio-over-fiber and radio-over-free-space optic links in a passive optical network architecture for ubiquitous wireless coverage. Two optical millimeter-wave generation techniques, ...
