GNPy Experimental Validation for Nyquist Subcarriers Flexible Transmission up to 800 G
Autor: Andrea D’Amico, Bertrand Le Guyader, Florian Frank, Esther Le Rouzic, Erwan Pincemin, Antonio Napoli, Han Sun, Bernhard Spinnler, Nicolas Brochier, Vittorio Curri
We test the performance of Nyquist subcarriers flexible transponders up to 800 Gbit/s over a 20×80-km optical link operated at full WDM spectral load, obtaining excellent accuracy in GSNR and optimal power predictions using GNPy.

GNPy experimental validation on flex-grid, flex-rate WDM optical transport scenarios
Autor: Florian Frank, Andrea D'Amico, Elliot London, Esther Le Rouzic, Nicolas Brochier, Bertrand Le Guyader, Erwan Pincemin, Vittorio Curri
Publikováno v: OFC
We demonstrate accurate GSNR predictions for a flex-grid and flex-rate experimental transmission using an enhanced implementation of the open-source GNPy library for a 1600 km OLS, involving QPSK, 8-QAM and 16-QAM modulation formats.

Stimulated Raman Scattering Impairments Induced by NGPON2 Introduction in Co-existing PONs
Autor: Philippe Chanclou, L. Guillo, Gael Simon, Bertrand Le Guyader, Fabienne Saliou
Publikováno v: OFC
We investigate on NGPON2 introduction effects in a coexisting PON topology. Simple optical power measurements permit to demonstrate that stimulated Raman scattering brings up to 3.9dB extra-losses on GPON. No other significant impairments were observ

An alternative architecture for a PON OLT splitter-combiner integrated into an SFP transceiver module
Autor: L. Guillo, David Piehler, Bertrand Le Guyader, Calvin Ho, Ken McGreer, Philippe Chanclou
Publikováno v: 2014 The European Conference on Optical Communication (ECOC).
A 1×N single-mode splitter made of (N-1) 2×2 couplers is simultaneously a low-loss N → 1 optical combiner when unused 2×2 coupler ports route to a mode-coupling receiver. A PIC-based SFP transceiver module providing four class-B+ GPON OLT ports
