La s\u00e9rie RV2X6376A est la premi\u00e8re diode DML de l’industrie \u00e0 supporter une vitesse maximale de 25 Gbps (par laser individuel) et une temp\u00e9rature industrielle (de -40\u00b0C \u00e0 95\u00b0C) sans refroidissement.<\/p>\n

La s\u00e9rie RV2X6376A est con\u00e7ue en modules \u00e9metteurs-r\u00e9cepteurs optiques compacts QSFP28 de 100 Gbps qui utilisent la modulation NRZ conventionnelle. Ils sont compatibles avec la norme Multiplexage en Longueur d’Onde Large (CWDM4 : Coarse Wavelength Division Multiplexing) qui sp\u00e9cifie quatre voies de 25 Gbps multiplex\u00e9es optiquement et d\u00e9multiplex\u00e9es \u00e0 partir d’une fibre monomode duplex. La s\u00e9rie RV2X6376A \u00e9tend la famille des diodes laser, rejoignant la s\u00e9rie NX6375AA \u00e9prouv\u00e9e et supportant une plage de temp\u00e9rature commerciale (-5\u00b0C \u00e0 75\u00b0C) utilis\u00e9e dans les centres de donn\u00e9es. En plus de fournir la robustesse et la fiabilit\u00e9 dont les stations de base ont besoin, la s\u00e9rie RV2X6376A offre \u00e9galement aux clients des centres de donn\u00e9es une mise \u00e0 niveau vers la plage de temp\u00e9rature industrielle plus large lorsqu’une marge suppl\u00e9mentaire est n\u00e9cessaire.<\/p>\n

Les communications mobiles et l’Internet des Objets (IoT) stimulent les syst\u00e8mes de communication optique \u00e0 haut d\u00e9bit, qui connaissent une croissance rapide en raison d’une explosion de l’utilisation des donn\u00e9es. Le Visual Networking Index (VNI) de Cisco\u00ae<\/sup>pr\u00e9voit que le trafic mondial de donn\u00e9es mobiles augmentera de 44% par an, passant de 11 000 p\u00e9taoctets\/mois en 2017 \u00e0 48 000 p\u00e9taoctets\/mois en 2021. Pour assurer cette hyper-croissance, les fabricants de stations de base passent \u00e0 une technologie 5G \u00e0 faible latence, et \u00e0 d\u00e9bit interm\u00e9diaire de 4.9G et plus.<\/p>\n

\u00ab\u00a0La s\u00e9rie RV2X6376A offre aux fabricants la solution de fiabilit\u00e9 la plus \u00e9lev\u00e9e pour les applications robustes de station de base ext\u00e9rieure 4.9 G et 5G\u00a0\u00bb, a d\u00e9clar\u00e9 Diwakar Vishakhadatta, Vice-Pr\u00e9sident pour les Communications Optiques Haute Vitesse et des Produits Sans Fil de Renesas Electronics Corporation. \u00ab\u00a0La large plage de temp\u00e9rature et la technologie DML des diodes \u00e0 puce nue permettent aux concepteurs d’\u00e9metteurs-r\u00e9cepteurs de r\u00e9aliser des co\u00fbts syst\u00e8me nettement inf\u00e9rieurs \u00e0 ceux des conceptions actuelles utilisant des diodes EML (Electro-absorption Modulated Laser).\u00a0\u00bb<\/p>\n
