30% Reach Increase via Low-complexity Hybrid HD/SD FEC and Nonlinearity-tolerant 4D Modulation
Gabriele Liga, Bin Chen, Sjoerd van der Heide +4
Current optical coherent transponders technology is driving data rates towards 1 Tb/s/λand beyond. This trend requires both high-performance coded modulation schemes and efficient…
Complexity-Adjustable SC Decoding of Polar Codes for Energy Consumption Reduction
Haotian Zheng, Bin Chen, Luis F. Abanto-Leon +2
This paper proposes an enhanced list-aided successive cancellation stack (ELSCS) decoding algorithm with adjustable decoding complexity. In addition, a logarithmic likelihood ratio…
Four-dimensional polarization-ring-switching for dispersion-managed optical fibre systems
Bin Chen, Chigo Okonkwo, Hartmut Hafermann +1
The recently introduced 4D 64-ary polarisation-ring-switching format is investigated in dispersion-managed systems. Numerical simulations show a reach increase of with respe…
Improving HD-FEC decoding via bit marking
Alex Alvarado, Gabriele Liga, Yi Lei +2
We review the recently introduced soft-aided bit-marking (SABM) algorithm and its suitability for product codes. Some aspects of the implementation of the SABM algorithm are discus…
11,700 km Transmission at 4.8 bit/4D-sym via Four-dimensional Geometrically-shaped Polarization-Ring-Switching Modulation
Sjoerd van der Heide, Bin Chen, Menno van den Hout +5
Using a novel geometrically-shaped four-dimensional modulation format, we transmitted 11x200 Gbit/s DWDM at 4.8 bit/4D-sym over 7,925 km and 11,700 km using EDFA-only and hybrid am…
Eight-dimensional Polarization-ring-switching Modulation Formats
Bin Chen, Chigo Okonkwo, Hartmut Hafermann +1
We propose two 8-dimensional (8D) modulation formats (8D-2048PRS-T1 and 8D-2048PRS-T2) with a spectral efficiency of 5.5 bit/4D-sym, where the 8 dimensions are obtained from two ti…
