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…

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…
