MDG and SNR Estimation in SDM Transmission Based on Artificial Neural Networks
Ruby S. B. Ospina, Menno van den Hout, Sjoerd van der Heide +7
The increase in capacity provided by coupled SDM systems is fundamentally limited by MDG and ASE noise. Therefore, monitoring MDG and optical SNR is essential for accurate performa…
Transoceanic Phase and Polarization Fiber Sensing using Real-Time Coherent Transceiver
Mikael Mazur, Jorge C. Castellanos, Roland Ryf +15
We implement a real-time coherent transceiver with fast streaming outputs for environmental sensing. Continuous sensing using phase and equalizer outputs over 12800km of a submarin…
Digital Interference Mitigation in Space Division Multiplexing Self-Homodyne Coherent Detection
Hanzi Huang, Yetian Huang, Haoshuo Chen +7
We propose a digital interference mitigation scheme to reduce the impact of mode coupling in space division multiplexing self-homodyne coherent detection and experimentally verify…
1.23-Tb/s per Wavelength Single-Waveguide On-Chip Optical Interconnect Enabled by Mode-division Multiplexing
Hanzi Huang, Yetian Huang, Yu He +7
We experimentally demonstrate a record net capacity per wavelength of 1.23~Tb/s over a single silicon-on-insulator (SOI) multimode waveguide for optical interconnects employing on-…
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…

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…
