Exploring and Experimenting with Shaping Designs for Next-Generation Optical Communications
Fanny Jardel, Tobias A. Eriksson, Cyril Méasson +4
A class of circular 64-QAM that combines 'geometric' and 'probabilistic' shaping aspects is presented. It is compared to square 64-QAM in back-to-back, single-channel, and WDM tran…
Transmission of Waveforms Determined by 7 Eigenvalues with PSK-Modulated Spectral Amplitudes
Henning Buelow, Vahid Aref, Wilfried Idler
2-ns waveforms with 7 eigenvalues and their QPSK-modulated spectral amplitudes were optimized by taking constraints of link, transmitter, and receiver into account. In experiment t…
Experimental Demonstration of Capacity Increase and Rate-Adaptation by Probabilistically Shaped 64-QAM
Fred Buchali, Georg Böcherer, Wilfried Idler +3
We implemented a flexible transmission system operating at adjustable data rate and fixed bandwidth, baudrate, constellation and overhead using probabilistic shaping. We demonstrat…
Experimental Demonstration of Nonlinear Frequency Division Multiplexed Transmission
Vahid Aref, Henning Buelow, Karsten Schuh +1
We experimentally demonstrate an NFDM optical system with modulation over nonlinear discrete spectrum. Particularly, each symbol carries 4-bits from multiplexing two eigenvalues mo…
High Speed Data Transmission over GI-MMF Using Mode Group Division Multiplexing
Bernd Franz, Liaquat Ali, Laurent Schmalen +1
We transmitted 4x28 Gbit/s over 5-km standard GI-MMF using four different mode groups in combination with direct detection and on-off-keying format (OOK). Due to the square-law det…
