Title (EN) SIGNAL SWITCHING DEVICE THROUGH OPTICAL MEANS AND SELF SWITCHES COMPRISING SUCH DEVICE
(FR) DISPOSITIF DE COMMUTATION DE SIGNAUX PAR DES MOYENS OPTIQUES ET AUTOCOMMUTATEURS COMPORTANT CE DISPOSITIF
Abstract: front page image
(EN)The switching device comprises a sender panel including a plurality of optical sender members connections respectively connected to incoming connections, a receiver panel including a plurality of optical members connected respectively to outgoing connections and optical means to project the image of the sender panel to the receiver panel, each of the members of one of the panels being comprised of an arrangement of optical or electro-optical elementary components in a quantity at least equal to the number of connection members of the other panel and further comprising switching means allowing the connection of at least one of these elementary components to the associated connection to said member; in such a device, it is necessary, on the one hand to control the switching means through calling signals, address signals, etc... and on the other hand to make sure that precise geometrical relationships of the positions between the connection members of both panels are provided. The control functions for switching and control of the position of the connection members are effected by means of additional optical or electro-optical members integral with both panels, which avoid the addition of many other electrical connection and to garantee a correct operation of the device. The device is particularly appropriate to self switches of telecommunication networks.
(FR)Dispositif de commutation du genre comprenant un tableau emetteur comportant une pluralite d"organes emetteurs optiques de liaison respectivement connectes a autant de liaisons entrantes, un tableau recepteur comportant une pluralite d"organes optiques de liaison respectivement connectes a autant de liaisons sortantes et des moyens optiques pour projeter l"image du tableau emetteur sur le tableau recepteur, chacun des organes de l"un des tableaux etant constitue par un arrangement de composants elementaires optiques ou electro-optiques en nombre au moins egal au nombre des organes de liaison de l"autre tableau et comportant en outre des moyens de commutation permettant de connecter au moins l"un de ces composants elementaires a la liaison associee audit organe; dans un tel dispositif, il est necessaire, d"une part de commander les moyens de commutation par des signaux d"appel, d"adresses, etc. et d"autre part de garantir des relations geometriques precises de position entre les organes de liaison de l"un et l"autre tableau. Conformement a l"invention, les fonctions de commande de commutation et de controle de position des organes de liaison sont realisees au moyen d"organes optiques ou electro-optiques supplementaires solidaires de l"un et l"autre tableau, ce qui permet d"eviter l"adjonction de nombreuses liaisons electriques et de garantir un fonctionnement correct du dispositif. Le dispositif de l"invention convient notamment a l"equipement d"autocommutateurs de reseaux de telecommunications.
