4D Geometric Shell Shaping with Applications to 400ZR
Sebastiaan Goossens, Yunus Can Gültekin, Olga Vassilieva +4
Geometric shell shaping is introduced and evaluated for reach increase and nonlinearity tolerance in terms of MI against PM-16QAM and PS-PM-16QAM in a 400ZR compatible transmission…
Introducing 4D Geometric Shell Shaping for Mitigating Nonlinear Interference Noise
Sebastiaan Goossens, Yunus Can Gültekin, Olga Vassilieva +4
Four dimensional geometric shell shaping (4D-GSS) is introduced as an approach for closing the nonlinearity-caused shaping gap. This format is designed at the spectral efficiency o…
Mitigating Nonlinear Interference by Limiting Energy Variations in Sphere Shaping
Yunus Can Gültekin, Alex Alvarado, Olga Vassilieva +4
Band-trellis enumerative sphere shaping is proposed to decrease the energy variations in channel input sequences. Against sphere shaping, 0.74 dB SNR gain and up to 9% increase in…
High-Cardinality Hybrid Shaping for 4D Modulation Formats in Optical Communications Optimized via End-to-End Learning
Vinícius Oliari, Boris Karanov, Sebastiaan Goossens +6
In this paper we carry out a joint optimization of probabilistic (PS) and geometric shaping (GS) for four-dimensional (4D) modulation formats in long-haul coherent wavelength divis…
Kurtosis-limited Sphere Shaping for Nonlinear Interference Noise Reduction in Optical Channels
Yunus Can Gültekin, Alex Alvarado, Olga Vassilieva +4
Nonlinear interference (NLI) generated during the propagation of an optical waveform through the fiber depends on the fourth order standardized moment of the channel input distribu…
First Experimental Demonstration of Probabilistic Enumerative Sphere Shaping in Optical Fiber Communications
Sebastiaan Goossens, Sjoerd van der Heide, Menno van den Hout +8
We transmit probabilistic enumerative sphere shaped dual-polarization 64-QAM at 350Gbit/s/channel over 1610km SSMF using a short blocklength of 200. A reach increase of 15% over co…
Enumerative Sphere Shaping for Rate Adaptation and Reach Increase in WDM Transmission Systems
Abdelkerim Amari, Sebastiaan Goossens, Yunus Can Gultekin +6
The performance of enumerative sphere shaping (ESS), constant composition distribution matching (CCDM), and uniform signalling are compared at the same forward error correction rat…
