Ce probl\u00e8me se r\u00e9sout avec de l'argent, mais tous souhaiteraient \u00e9viter des d\u00e9penses suppl\u00e9mentaires. La solution propos\u00e9e par les chercheurs repose justement sur cette notion : il est possible d'augmenter la bande passante sans changer l'infrastructure, bien qu'il soit \u00e9vident qu'il faudra utiliser du nouvel \u00e9quipement pour l'envoi et la r\u00e9ception. Mais cela ne se compare clairement pas aux co\u00fbts li\u00e9s au d\u00e9ploiement de nouvelles lignes de transmission optiques.<\/p>\n<p>Les chercheurs de l'Universit\u00e9 d'Aston, de l'Institut national japonais des technologies de l'information et des communications (NICT) et de Nokia Bell Labs aux \u00c9tats-Unis fondent leur proposition sur l'extension des plages de transmission de donn\u00e9es. Traditionnellement, la fibre optique fonctionnait sur les plages de longueurs d'onde C et L. Ensuite, les chercheurs ont int\u00e9gr\u00e9 deux autres plages : E et S. Enfin, dans leurs travaux r\u00e9cents, ils ont mobilis\u00e9 deux plages suppl\u00e9mentaires - O et U. La derni\u00e8re a \u00e9t\u00e9 la plus difficile \u00e0 mettre en \u0153uvre, car il n'existe pas de r\u00e9cepteurs et d'\u00e9metteurs correspondants sur le march\u00e9. L'\u00e9quipe de scientifiques britanniques a d\u00fb concevoir et fabriquer son propre \u00e9quipement. <\/p>\n<p><center><\/center> <\/p>\n<p>Le Dr Phillips de l'Universit\u00e9 d'Aston a d\u00e9clar\u00e9 : \u00ab Cette d\u00e9couverte pourrait aider \u00e0 augmenter la bande passante d'une fibre optique, permettant au monde d'obtenir un syst\u00e8me plus performant. On s'attend \u00e0 ce que la technologie r\u00e9cemment d\u00e9velopp\u00e9e contribue de mani\u00e8re significative \u00e0 l'augmentation de la bande passante des infrastructures de communication optique, car les futurs services de transmission de donn\u00e9es devraient rapidement accro\u00eetre la demande \u00bb.<\/p>\n<p><strong>Source :<\/strong><\/p>\n<ul
