Les fibres multicœurs à multiplexage par répartition en longueur d'onde peuvent transmettre une grande quantité d'informations sur une seule fibre, et les allocations de cœurs à haute densité permettent de déployer un grand nombre de lignes de fibres dans des espaces limités. Cependant, la diaphonie inter-cœurs dégrade le signal dans ces systèmes. Cet article décrit la conception d'un schéma d'entrelacement de fréquences pour une fibre multicœur hexagonale à 7 cœurs. Les schémas d'entrelacement décalent les spectres de signaux entre les cœurs voisins pour réduire la dégradation du signal provoquée par la diaphonie inter-cœurs. L'allocation de fréquence de canal qui réduit le plus efficacement le taux d'erreur sur les bits est déterminée numériquement dans cette étude. Les résultats indiquent que l'entrelacement de fréquence optimal améliore le rapport de diaphonie admissible de 6.3 dB pour les signaux QPSK, démontrant ainsi son potentiel pour améliorer les systèmes de transmission par fibre multicœur à multiplexage par répartition en longueur d'onde.

Abstract: Wavelength-division multiplexing multicore fibers can transmit a large amount of information over one fiber, and high-density core allocations enable a large number of fiber lines to be deployed in limited spaces. However, inter-core crosstalk degrades the signal in these systems. This paper describes the design of a frequency interleaving scheme for a 7-core hexagonal multicore fiber. Interleaving schemes shift signal spectra between neighboring cores to reduce the signal degradation caused by inter-core crosstalk. The channel frequency allocation that most efficiently lowers the bit error rate is numerically determined in this study. The results indicate that the optimum frequency interleaving improves the allowable crosstalk ratio by 6.3 dB for QPSK signals, demonstrating its potential for improving wavelength-division multiplexing multicore fiber transmission systems.

AB - Wavelength-division multiplexing multicore fibers can transmit a large amount of information over one fiber, and high-density core allocations enable a large number of fiber lines to be deployed in limited spaces. However, inter-core crosstalk degrades the signal in these systems. This paper describes the design of a frequency interleaving scheme for a 7-core hexagonal multicore fiber. Interleaving schemes shift signal spectra between neighboring cores to reduce the signal degradation caused by inter-core crosstalk. The channel frequency allocation that most efficiently lowers the bit error rate is numerically determined in this study. The results indicate that the optimum frequency interleaving improves the allowable crosstalk ratio by 6.3 dB for QPSK signals, demonstrating its potential for improving wavelength-division multiplexing multicore fiber transmission systems.
