Trellis shaping for reduction of the peak-to-average power ratio in coherent optical OFDM systems
TL;DR: In this article, a frequency-domain method with good structural properties for reduction of the PAPR in coherent optical OFDM systems was proposed, and it was shown that the nonlinear threshold can be increased considerably at modest redundancy.
Proceedings ArticleDOI
Timing Advance Tracking for Coherent OFDMA-PON Upstream System
Christian Ruprecht,Kai Habel,Johannes von Hoyningen-Huene,Yingkan Chen,Norbert Hanik,Werner Rosenkranz +5 more
TL;DR: In this article, a synchronization algorithm for coherent OFDMA-PON upstream is proposed, and the feasibility of the tracking functionality is experimentally investigated at the ONU with a differential delay of up to 37.6 ns.
Proceedings ArticleDOI
Low computational complexity mode division multiplexed ofdm transmission over 130 km of few mode fiber
Beril Inan,Yongmin Jung,Vincent A. J. M. Sleiffer,Maxim Kuschnerov,L. Nielsen,Susmita Adhikari,Sander L. Jansen,David J. Richardson,Shaif-ul Alam,Bernhard Spinnler,Norbert Hanik +10 more
TL;DR: It is confirmed that OFDM can significantly reduce the required DSP complexity to compensate for differential mode delay, a key step towards real-time MDM transmission.
Proceedings ArticleDOI
Record field demonstration of C-band multi-terabit 16QAM, 32QAM and 64QAM over 762km of SSMF
Talha Rahman,Danish Rafique,Bernhard Spinnler,Erwan Pincemin,Claude Le Bouette,Jeremie Jauffrit,Stefano Calabro,Erik De Man,Sylvain Bordais,Uwe Feiste,Juraj Slovak,Antonio Napoli,Ginni Khanna,Norbert Hanik,Celine Andre,Chigo Okonkwo,Maxim Kuschnerov,A.M.J. Koonen,Christian Dourthe,Bruno Raguenes,Bernd Sommerkorn-Krombholz,Marc Bohn,Huug de Waardt +22 more
TL;DR: In this article, the authors demonstrate a record 38.4Tb/s 64QAM C-band transmission over 762km of field deployed SSMF fiber, connecting Lyon and Marseille, France, employing hybrid EDFA-Raman amplification and achieve a spectral efficiency of 8 b/s/Hz.
Proceedings ArticleDOI
Digital back-propagation of a superchannel: Achievable rates and adaption of the GN model
Tobias Fehenberger,Norbert Hanik +1 more
TL;DR: The impact of back-propagating an entire superchannel and sub-channels thereof is quantified by evaluating mutual information and a 50 Gb/s per channel increase in data rate is reported.
