56 Gb/s, PAM-4 Transmission Over 25 km, Using IQ Modulator and Unequally Spaced Levels

Prodaniuc, Cristian; Stojanovic, Nebojsa; Karinou, Fotini; Goeger, Gernot; Qiang, Zhang; Llorente, Roberto (Optical Society (OSA), 2015-05-15)

[EN] We propose a PAM-4 modulation scheme with unequally spaced levels in order to mitigate chirp effects caused by IQ modulators. Experimental results of 56 Gb/s transmission over 25 km link demonstrate the robustness of ...
Advanced Signal Processing for Pulse-Amplitude Modulation Optical Transmission Systems

Prodaniuc, Cristian (Universitat Politècnica de València, 2019-02-25)

[ES] Los sistemas de transmisión óptica no-coherente se emplean actualmente en las redes ópticas de corto alcance (< 80 km), como son las redes de ámbito metropolitano. La implementación más común en el estado del arte se ...
Partial response signaling for improved chromatic dispersion tolerance in intensity modulation optical transmissions

Prodaniuc, Cristian; Stojanovic, Nebojsa; Karinou, Fotini; Llorente, Roberto (The Optical Society, 2018)

[EN] We investigate partial response signaling (PRS) as a way of increasing the transmission length achievable by direct detection optical systems. The performance of the duobinary and PRS modulations is evaluated against ...
Performance Comparison Between 4D Trellis Coded Modulation and PAM-4 for Low-Cost 400 Gbps WDM Optical Networks

Prodaniuc, Cristian; Stojanovic, Nebojsa; Karinou, Fotini; Qiang, Zhang; Llorente Sáez, Roberto (Institute of Electrical and Electronics Engineers, 2016)

[EN] We investigate two trellis-coded modulation (TCM) schemes for use in next-generation low-cost 400G optical networks. Their performance is evaluated against that of four-level pulse amplitude modulation (PAM-4). We ...
