Field Trial of a Flexible Real-time Software-defined GPU-based Optical Receiver
Sjoerd van der Heide, Ruben S. Luis, Benjamin J. Puttnam +6
We introduce a flexible, software-defined real-time multi-modulation format receiver implemented on an off-the-shelf general-purpose graphics processing unit (GPU). The flexible re…
1 Tbit/s/ Transmission Over a 130 km Link Consisting of Graded-Index 50 m Core Multi-Mode Fiber and 6LP Few-Mode Fiber
Menno van den Hout, Sjoerd van der Heide, John van Weerdenburg +7
We demonstrate 1 Tbit/s/ single-span transmission over a heterogeneous link consisting of graded-index 50 m core multi-mode fiber and 6LP few-mode fiber using a Kramers-Kroni…
Experimental validation of MDL emulation and estimation techniques for SDM transmission systems
Menno van den Hout, Ruby S. B. Ospina, Sjoerd van der Heide +8
We experimentally validate a mode-dependent loss (MDL) estimation technique employing acorrection factor to remove the MDL estimation dependence on the SNR when using a minimum mea…
Exploiting Angular Multiplexing for Polarization-diversity in Off-axis Digital Holography
Sjoerd van der Heide, Rutger van Anrooij, Menno van den Hout +9
Digital holography measures the complex optical field and transfer matrix of a device, polarization-diversity is often achieved through spatial multiplexing. We introduce angular m…
Real-time, Software-Defined, GPU-Based Receiver Field Trial
Sjoerd van der Heide, Ruben S. Luis, Benjamin J. Puttnam +6
We demonstrate stable real-time operation of a software-defined, GPU-based receiver over a metropolitan network. Massive parallelization is exploited for implementing direct-detect…
Nonlinear Interference Analysis of Probabilistic Shaping vs. 4D Geometrically Shaped Formats
Bin Chen, Chigo Okonkwo, Alex Alvarado
Performance trade-offs between linear shaping and nonlinear tolerance of the recently introduced 4D orthant-symmetric 128-ary modulation format are investigated. Numerical simulati…
Mode-dependent Loss and Gain Estimation in SDM Transmission Based on MMSE Equalizers
Ruby S. B. Ospina, Menno van den Hout, Juan Carlos Alvarado-Zacarias +7
The capacity in space division multiplexing (SDM) systems with coupled channels is fundamentally limited by mode-dependent loss (MDL) and mode-dependent gain (MDG) generated in com…
Revisiting Efficient Multi-Step Nonlinearity Compensation with Machine Learning: An Experimental Demonstration
Vinícius Oliari, Sebastiaan Goossens, Christian Häger +7
Efficient nonlinearity compensation in fiber-optic communication systems is considered a key element to go beyond the "capacity crunch''. One guiding principle for previous work on…
Analysis and Experimental Demonstration of Orthant-Symmetric Four-dimensional 7 bit/4D-sym Modulation for Optical Fiber Communication
Bin Chen, Alex Alvarado, Sjoerd van der Heide +3
We propose a new four-dimensional orthant-symmetric 128-ary modulation format (4D-OS128) with a spectral efficiency of 7bit/4D-sym. The proposed format fills the gap between polari…
