Correlation and Power Distribution of Intercore Crosstalk Field Components of Polarization-Coupled Weakly Coupled Single-Mode Multicore Fibres [PDF]
Photonics, 2021 The correlation and power distribution of intercore crosstalk (ICXT) field components of weakly coupled multicore fibers (WC-MCFs) are important properties that determine the statistics of the ICXT and ultimately impact the performance of WC-MCF optical ...

Impact of Intercore Crosstalk on the Transmission Distance of QAM Formats in Multicore Fibers
IEEE Photonics Journal, 2016 We investigate the impact of intercore crosstalk on the achievable transmission distance of three square quadrature amplitude modulation (QAM) formats. We show that increasing intercore crosstalk across an 18 dB range starting from −43.4 dB/100 km

5G fronthauls with multicore fibers: CPRI signals performance degradation induced by intercore crosstalk [PDF]
Broadband Access Communication Technologies XIII, 2023 Weakly-coupled multicore fibers (MCFs) have been proposed to support the huge data capacity demanded by future 5G fronthauls. However, in MCFs, intercore crosstalk (ICXT), i.e., power coupling between different MCF cores, can degrade significantly the ...

Review of the discrete changes model of intercore crosstalk in weakly-coupled multicore fibers [PDF]
2020 22nd International Conference on Transparent Optical Networks (ICTON), 2020 We review the discrete changes model (DCM) of intercore crosstalk (ICXT) in weakly-coupled multicore fiber systems. The stochastic time evolution, decorrelation bandwidth and polarization fluctuations over time of the ICXT are analysed numerically and ...
