X Display Company (XDC) vient de lancer un \u00e9cran r\u00e9volutionnaire dont la vitesse est d’un million d’images par seconde, la plus rapide jamais signal\u00e9e \u00e0 ce jour. Cette innovation ouvre la voie \u00e0 des syst\u00e8mes avanc\u00e9s de communication optique sans fil, am\u00e9liorant la connectivit\u00e9 dans les centres de donn\u00e9es d’intelligence artificielle gr\u00e2ce \u00e0 des liaisons \u00e9cran-cam\u00e9ra \u00e9volutives, sans c\u00e2ble et \u00e9conomes en \u00e9nergie.<\/h2>\n

Les \u00e9crans XDC sont con\u00e7us pour la communication de machine \u00e0 machine et utilisent des milliers d \u00ab \u00e9metteurs ultrarapides, \u00e0 longueurs d’onde multiples et \u00e0 transmission parall\u00e8le. Le syst\u00e8me \u00e9crit et contr\u00f4le dynamiquement les donn\u00e9es sur des trames s\u00e9quentielles discr\u00e8tes, chaque trame \u00e9tant transmise optiquement par l \u00bb \u00e9cran puis lue par une cam\u00e9ra r\u00e9ceptrice \u00e0 grande vitesse. La mod\u00e9lisation de l’efficacit\u00e9 \u00e9nerg\u00e9tique de la liaison montre une feuille de route pour une am\u00e9lioration de 2 \u00e0 3 fois de la puissance par bit (pJ\/bit) par rapport aux \u00e9metteurs-r\u00e9cepteurs optiques 800G – un avantage significatif pour les centres de donn\u00e9es \u00e0 grande \u00e9chelle \u00e0 la recherche d’une infrastructure plus verte et plus reconfigurable.<\/p>\n

\u00ab\u00a0Nous voyons des concepts et des \u00e9l\u00e9ments de technologies d’affichage microLED se pr\u00e9parer \u00e0 servir le march\u00e9 des communications optiques des centres de donn\u00e9es et se positionner pour transformer l’interconnectivit\u00e9 \u00e0 l’int\u00e9rieur des centres de donn\u00e9es\u00a0\u00bb, a d\u00e9clar\u00e9 Eric Virey, PhD, analyste principal du march\u00e9 et des technologies d’affichage au sein de la division Photonique, d\u00e9tection et affichage de Yole Group. Avec l’av\u00e8nement de l’IA et la mont\u00e9e en puissance des r\u00e9seaux neuronaux, des solutions de connectivit\u00e9 plus \u00e9volutives et durables permettront d’all\u00e9ger le fardeau de l’\u00e9nergie, de l’infrastructure de r\u00e9seau et du co\u00fbt total de possession (TCO) pour les centres de donn\u00e9es \u00e0 grande \u00e9chelle. Le lien optique bas\u00e9 sur l’affichage de XDC permet aux donn\u00e9es de voler – litt\u00e9ralement – dans l’air, \u00e9liminant ainsi le besoin de faisceaux de fibres physiques pour former des clusters xPU, tout en s’adaptant dynamiquement en temps r\u00e9el aux changements dans la demande de bande passante.<\/p>\n

\u00ab Cette perc\u00e9e inaugure un tout nouveau paradigme dans lequel les \u00e9crans transcendent leur r\u00f4le traditionnel de simples interfaces pour les humains, en \u00e9voluant vers des transmetteurs de donn\u00e9es optiques entre les machines \u00bb, a d\u00e9clar\u00e9 Nikhil Jain, directeur de l’opto\u00e9lectronique et des partenariats strat\u00e9giques chez X Display. \u00ab La capacit\u00e9 de transmettre dynamiquement des donn\u00e9es \u00e0 des vitesses de l’ordre du m\u00e9gahertz \u00e0 travers l’air est une promesse de transformation pour l’infrastructure du cloud. \u00c0 l’avenir, gr\u00e2ce \u00e0 une innovation continue, les bandes passantes de l’ordre du t\u00e9rabit par seconde et au-del\u00e0 sont \u00e0 port\u00e9e de main, facilitant une communication optique \u00e9volutive, modulaire et \u00e9conome en \u00e9nergie, et ouvrant la voie \u00e0 des applications pionni\u00e8res telles que l’informatique optique. \u00bb
\nLa plateforme n’est pas seulement une solution de communication de donn\u00e9es optiques convaincante, mais elle offre \u00e9galement des \u00e9l\u00e9ments de base pour des applications couvrant le LiFi, la diffusion de m\u00e9dias num\u00e9riques, la communication par lumi\u00e8re visible (VLC), les r\u00e9seaux ad hoc v\u00e9hiculaires (VANET) et l’informatique optique \u00e9conome en \u00e9nergie.<\/p>\n
