Full C-Band WDM Transmission of Nonlinearity-Tolerant Probabilistically Shaped QAM over 2824-km Dispersion-Managed Fiber
Junho Cho, Xi Chen, Greg Raybon +3
By tailoring probabilistic constellation shaping (PCS) for nonlinearity tolerance, we experimentally demonstrate up to 1.1 dB increase in signal-to-noise ratio (SNR) and 6.4% incre…
Supply-Power-Constrained Cable Capacity Maximization Using Multi-Layer Neural Networks
Junho Cho, Sethumadhavan Chandrasekhar, Erixhen Sula +9
We experimentally solve the problem of maximizing capacity under a total supply power constraint in a massively parallel submarine cable context, i.e., for a spatially uncoupled sy…
Supply-Power-Constrained Cable Capacity Maximization Using Deep Neural Networks
Junho Cho, Sethumadhavan Chandrasekhar, Erixhen Sula +9
We experimentally achieve a 19% capacity gain per Watt of electrical supply power in a 12-span link by eliminating gain flattening filters and optimizing launch powers using machin…
First Transmission of a 12D Format Across 3 Coupled Spatial Modes of a 3-Core Coupled-Core Fiber at a Spectral Efficiency of 4 bits/s/Hz
René-Jean Essiambre, Roland Ryf, Sjoerd van der Heide +10
We demonstrate the first transmission of a new twelve-dimensional modulation format over a three-core coupled-core multicore fiber. The format occupies a single time slot spread ac…
