Joint-polarization carrier phase estimation for XPM-limited coherent polarization-multiplexed QPSK transmission with OOK-neighbors
M. Kuschnerov,D. van den Borne,K. Piyawanno,Fabian N. Hauske,C.R.S. Fludger,T. Duthel,T. Wuth,J. C. Geyer,C. Schulien,Bernhard Spinnler,E.-D. Schmidt,Berthold Lankl +11 more
TL;DR: In this paper, joint polarization carrier phase estimation for XPM-limited channels with significant improvements over standard methods was demonstrated on measurements of 43 Gb/s NRZ-CP-QPSK with 10.7 Gb /s OOK neighbors.
Journal ArticleDOI
Maximum-Likelihood Detection in Few-Mode Fiber Transmission With Mode-Dependent Loss
Adriana Lobato,Filipe Ferreira,Beril Inan,Susmita Adhikari,Maxim Kuschnerov,Antonio Napoli,Bernhard Spinnler,Berthold Lankl +7 more
TL;DR: In this paper, the performance of maximum likelihood detection is evaluated and compared with the zeroforcing (ZF) and minimum mean square error (MMSE) equalizers for a 3 × 158-Gb/s mode-division multiplexed dual-polarization quadrature phase shift keying orthogonal frequency division multiplexing transmission impaired by mode-dependent loss.
Journal ArticleDOI

Koonen,Huug de Waardt +19 more
TL;DR: In this paper, the authors conducted several high capacity experiments with tier-1 operator Orange using their field deployed standard single mode fiber (SSMF, G.652), having a total length of 762 km, connecting the cities Lyon and Marseille in France.
Journal ArticleDOI
Flex-grid optical networks: spectrum allocation and nonlinear dynamics of super-channels
Danish Rafique,Talha Rahman,Antonio Napoli,Maxim Kuschnerov,Gottfried Lehmann,Bernhard Spinnler +5 more
TL;DR: This paper reports on the spectrum allocation strategies based on the impact of inter-channel fiber nonlinearities, for PM-16QAM channels -termed as super-channels, and shows that for high dispersion fibers, both homogenous and heterogeneous spectrum allocation enable similar performance, i.e. the nonlinear impact of hybrid traffic is found to be minimal.
Proceedings ArticleDOI
Low complexity carrier recovery for coherent QAM using superscalar parallelization
TL;DR: The combination of superscalar parallelization with feedback carrier recovery provides performance close to the theoretical limit on carrier recovery for coherent optic receivers.
