Real-Time MIMO Transmission over Field-Deployed Coupled-Core Multi-Core Fibers

We perform parallel continuous measurements of deployed SDM fibers using real-time coherent receivers implemented on FPGAs. Fast readouts enabling real-time tracking of the DSP implementation, showing that coupled-core fibers are compatible with real-time DSP implementations. (C) 2022 The Author(s)

Automated summary

In this study, parallel continuous measurements of deployed space-division multiplexing (SDM) fibers are carried out using real-time coherent receivers implemented on FPGAs. The fast readouts enable real-time tracking of the DSP implementation, demonstrating the compatibility of coupled-core fibers with real-time DSP implementations.
