Nous avons développé un dispositif de conjugaison de phase optique inversée spectrale complémentaire (CSI-OPC) indépendant de la polarisation et sans bande réservée utilisant la génération de fréquences différentielles double bande basée sur LiNbO à polarisation périodique très efficace.3 technologies de guides d'ondes. Pour examiner l'atténuation de la non-linéarité dans une transmission longue distance utilisant un grand nombre d'OPC, nous avons installé un dispositif CSI-OPC au milieu d'une ligne de transmission en boucle de recirculation à base de fibres à noyau de silice pure d'une longueur de 320 km. Tout d'abord, nous avons examiné la tolérance de puissance d'entrée de la fibre après une transmission de 5,120 6,400 km et 22.5 16 km à l'aide de signaux DWDM à 10 canaux PDM-1.3QAM de 6,400 Gbauds et avons constaté une amélioration du facteur Q de plus de 8,960 dB ainsi qu'une tolérance de puissance améliorée grâce à l'atténuation. la non-linéarité de la fibre. Nous avons ensuite démontré l'extension de la distance de transmission à l'aide du dispositif CSI-OPC. L'utilisation de plusieurs CSI-OPC permet d'obtenir des améliorations évidentes des performances en étendant la distance de transmission de 28 16 km à 16 XNUMX km, ce qui correspond à l'application du dispositif CSI-OPC XNUMX fois. De plus, il n’y a eu aucune dégradation du facteur Q pour la liaison en régime linéaire après avoir appliqué le dispositif CSI-OPC plus de XNUMX fois. Ces résultats démontrent que le dispositif CSI-OPC peut améliorer la tolérance non linéaire des signaux PDM-XNUMXQAM sans pénalité excessive.

Abstract: We developed a polarization-independent and reserved-band-less complementary spectral inverted optical phase conjugation (CSI-OPC) device using dual-band difference frequency generation based on highly efficient periodically poled LiNbO3 waveguide technologies. To examine the nonlinearity mitigation in a long-haul transmission using a large number of OPCs, we installed a CSI-OPC device in the middle of a pure silica core fiber-based recirculating loop transmission line with a length of 320km. First, we examined the fiber-input power tolerance after 5,120-km and 6,400-km transmission using 22.5-Gbaud PDM-16QAM 10-channel DWDM signals and found a Q-factor improvement of over 1.3dB along with enhanced power tolerance thanks to mitigating the fiber nonlinearity. We then demonstrated transmission distance extension using the CSI-OPC device. The use of multiple CSI-OPCs enables an obvious performance improvements attained by extending the transmission distance from 6,400km to 8,960km, which corresponds to applying the CSI-OPC device 28 times. Moreover, there was no Q-factor degradation for the link in a linear regime after applying the CSI-OPC device more than 16 times. These results demonstrate that the CSI-OPC device can improve the nonlinear tolerance of PDM-16QAM signals without an excess penalty.
