CA 2117301

At the input of said matrix, a series of emitters (E1, 1... Em,n) receive data to be transmitted through the latter. The emitters emit, on controlled wavelengths, waves carrying said data. A series of filters (F1, 1... Fn,m) selectively transmit these waves at the output of the matrix according to their wavelengths. From the emitters to the filters, the waves are transmitted firstly by a group of switching distributors (X1... Xm), each capable of controllably connecting each of its inputs to each of its outpouts, then by a group of star distributors (C1... Cn), each permanently connecting all its inputs to all its outputs. Application especially in a telecommunications network, requiring a simplified data collection system.

2117301 9409602 PCTABS00166 En entrée de cette matrice un ensemble d'émetteurs (E1, 1... Em,n) reçoit des informations à transmettre à travers celle-ci. Il émet, sur des longueurs d'onde commandées, des ondes portant ces informations. Un ensemble de filtres (F1, 1... Fn,m) transmet ces ondes en sortie de la matrice sélectivement selon leurs longueurs d'onde. De ces émetteurs à ces filtres ces ondes sont transmises d'abord par un groupe de distributeurs à commutation (X1... Xm) aptes chacun à raccorder selon commande chacune de ses entrées à chacune de ses sorties, puis par un groupe de distributeurs en étoile (C1... Cn) raccordant chacun en permanence toutes ses entrées à toutes ses sorties. Cette invention trouve notamment application dans un réseau de télécommunication lorsqu'une opération de collection d'informations doit pouvoir être réalisée simplement.
