Sequence Selection with Dispersion-Aware Metric for Long-Haul Transmission Systems
Jingtian Liu, Élie Awwad, Hartmut Hafermann +1
We introduce a novel sign-dependent metric: the energy dispersion index (EDI) of sequences that endured chromatic dispersion, denoted as D-EDI, which exhibits a more accurate oppos…
Multi-dimensional Energy Limitation in Sphere Shaping for Nonlinear Interference Noise Mitigation
Jingtian Liu, Élie Awwad, Yves Jaouën
We propose Four-Dimensional (4D) energy limit enumerative sphere shaping (ESS) of -QAM signaling to minimize rate loss and improve the transmission performance over non-linear W…
Fault-Tolerant Four-Dimensional Constellation for Coherent Optical Transmission Systems
Jingtian Liu, Élie Awwad, Yves Jaouën
We propose a 4-dimensional 2-ary amplitude ring-switched modulation format with 64 symbols, which is denoted as 4D-2A-RS64 encoded over two polarization tributaries to improve the…
Equalization in Dispersion-Managed Systems Using Learned Digital Back-Propagation
Mohannad Abu-Romoh, Nelson Costa, Yves Jaouën +4
In this paper, we investigate the use of the learned digital back-propagation (LDBP) for equalizing dual-polarization fiber-optic transmission in dispersion-managed (DM) links. LDB…
