Abstract
De nos jours, avec l'explosion de transfert d'informations, les fibres optiques deviennent toujours plus rapides. Pour la plupart, les derniers progrès concernant les quantités de données que ces fibres peuvent transmettre par unité de temps ont été réalisés en ajoutant de plus en plus de longueurs d'onde en même temps (appelées lambdas) à la même fibre, un procédé que l'on appelle DWDM (multiplexage en longueur d'onde dense). Actuellement, une seule fibre optique peut se voir attribuer 80 ou même 160 lambdas différentes en même temps et il est probable que ce nombre s'accroisse. A ce jour, les débits binaires les plus rapides pour chaque lambda se situent autour de 10 ou 40 gigabits par seconde, mais il sera difficile de faire beaucoup mieux, étant donné que les débits binaires élevés présentent une tolérance bien moindre au problèmes de dispersion. Néanmoins, la demande de communications en bande large, alimentée principalement par la croissance d'Internet, ne cesse d'augmenter à un taux bien plus rapide que les capacités des fibres optiques. Par exemple, ces dernières années cette demande se multipliait par cinq chaque année et il est probable qu'elle continue d'augmenter. Actuellement, les efforts se concentrent principalement sur l'accroissement du nombre de Lambdas par fibre, mais une fois qu'il aura été doublé quelques fois de plus, il deviendra difficile de l'accroître davantage. La présente invention vise à effectuer un grand bond dans ce domaine en atteignant un nombre beaucoup plus important de fibres par câble, par exemple 1000 ou 10.000 fois le nombre actuel, avec une diminution des coûts réduits de plusieurs ordres de grandeur. La présente invention permet de résoudre différents problèmes mécaniques, optiques et électroniques que pose la concentration d'un si grand nombre de fibres dans un seul câble. Une des principales caractéristiques de la présente invention consiste en l'utilisation de gaines plates flexibles multifibre qui peuvent se déplacer librement à l'intérieur du tuyau du câble, le tuyau étant de préférence divisé en au moins deux cellules, de sorte qu'il puisse s'infléchir uniquement dans la direction souhaitée et présenter un force structurelle maximale. Une autre caractéristique principale consiste en la possibilité qu'ont les connecteurs destinés à ces gaines de pouvoir également résoudre bon nombre d'autres problèmes. Une autre caractéristique importante concerne différents procédés permettant d'optimiser l'efficacité d'amplification de plusieurs fibres à la fois.
