Abstract

Face à l'explosion actuelle du transfert d'informations, le transfert par fibres optiques devient de plus en plus rapide. La plupart des progrès récents concernant le volume de données que les fibres peuvent transporter par unité de temps ont consisté à ajouter simultanément de plus en plus de longueurs d'onde (appelées lambdas) à la même fibre, procédé appelé DWDM (multiplexage en longueur d'onde dense). Aujourd'hui, une seule fibre optique peut transporter jusque sur 80 voire même 160 différentes lambdas simultanément et ce nombre est susceptible d'augmenter encore. Les débits binaires les plus élevés atteints jusqu'à maintenant par lambda avoisinent 10 ou 40 gigabits par seconde, et il sera difficile de faire mieux étant donné qu'avec des débits binaires supérieurs la tolérance aux problèmes de dispersion est plus faible. Néanmoins, la demande en communications large bande, alimentée principalement par le développement d'Internet, est en constante augmentation et ce, beaucoup plus rapidement que l'augmentation des capacités des fibres optiques. Globalement, cette demande a quintuplé annuellement ces dernières années, et elle va probablement continuer à augmenter. Actuellement, on se concentre principalement sur l'augmentation du nombre de lambdas par fibre, mais après les avoir doublées quelques fois de plus il sera difficile de les augmenter encore. Les système et procédé de l'invention permettent de faire un bond important dans ce domaine par ils donnent la possibilité de prévoir plus de fibres par câble, par exemple jusqu'à 1 000 ou 10 000 fois plus qu'aujourd'hui, avec une augmentation des coût proportionnellement plus faible. Ils permettent de résoudre divers problèmes mécaniques, optiques et électroniques provenant de la tentative d'insérer autant de fibres dans un câble. Une des caractéristiques les plus importantes de l'invention est l'utilisation d'enveloppes plates souples à fibres multiples pouvant se déplacer librement dans le tube pour câble, le tube étant de préférence divisé en au moins deux cellules, de sorte qu'il fléchisse uniquement dans la direction voulue et qu'il possède une résistance structurale maximum, et les connecteurs pour lesdites enveloppes peuvent également permettre de résoudre de nombreux autres problèmes. Une autre caractéristique importante est la réduction sensible du coût de l'équipement fini par un procédé nouveau de duplication de chaque lambda dans les fibres multiples et la modulation par tout ou rien séparée pour chaque fibre, si bien qu'un nombre moins important de sources laser est nécessaire.
