PCT No. PCT/FR79/00102 Sec. 371 Date Jul. 8, 1980 Sec. 102(e) Date Jul. 8, 1980 PCT Filed Nov. 8, 1979 PCT Pub. No. WO80/01028 PCT Pub. Date May 15, 1980.The switching device according to the invention is of the type comprising a transmit board having a plurality of optical link emitter elements respectively connected to an equal number of incoming links, a receive board comprising a plurality of optical link elements respectively connected to an equal number of outgoing links and optical means for projecting the image of the emitter board on the receive board, each of the elements of one of the boards being constituted by an array of elementary optical or electro-optical components in a number at least equal to the number of the link elements of the other board and comprising in addition switching means making it possible to connect at least one of these elementary components to the link associated with said element; in such a device, it is necessary, on one hand, to control the switching means by call signals, address signals, etc., . . . and, on the other hand, to guarantee precise geometric relationships with regard to position between the link elements of the one and the other board. According to the invention, the functions of switching control and positional control of the elements of the links are realized by means of optical or electro-optical supplementary elements fast with one and the other board, which allows to dispense with numerous electrical links and to guarantee a correct functioning of the device. The device of the invention is suitable in particular for equipping automatic switching units in telecommunication networks. |
