Abstract

L'invention porte sur un système d'interconnexion optique sans contrainte d'espace tolérant aux décalages et utilisant les éléments redondants d'un émetteur et/ou récepteur. Ces éléments se présentent sous forme de groupes, le nombre de groupes étant redondant, et le nombre d'éléments de chaque groupe étant suffisant pour loger le nombre de canaux de données à transmettre. Le système comprend également un dispositif destiné à identifier les décalages entre l'émetteur et le récepteur correspondant, ce dispositif permettant d'assurer le retour entre l'émetteur et le récepteur en ce qui concerne le décalage ; un dispositif pour réacheminer les données provenant du groupe décalé vers le groupe redondant et qui réoriente, par conséquent, les données vers/à partir de l'emplacement physique correct. De préférence, les éléments sont disposés sous forme d'ensembles unidimensionnels ou bidirectionnels, les éléments de l'émetteur étant des émetteurs optiques ou des modulateurs optiques. Des systèmes de liaison unidirectionnels et bidirectionnels sont mis en place dans diverses réalisations de cette invention. L'invention porte en outre sur un procédé visant à compenser les décalages dans un système d'interconnexion optique sans contrainte d'espace qui possède des éléments redondants de l'émetteur ou du récepteur.
