An optoelectronic switching network for multi-service wide-band telecommunications systems includes, on the one hand, a selector board (receiver or emitter) carrying plural compound optoelectronic units (selector units) each including a matrix of optoelectronic cells (photo diodes or light emitting diodes) and cell selection means and, on the other hand, a board (emitter or receiver) carrying plural optoelectronic units (conjugated units) optically conjugated with each compound unit of the selector board. To reduce the number of selector units, the selection means of each selector unit include means for respectively connecting cells, each of which is selected in a zone among plural zones from the matrix, to the links of plural channel links connected to the selector unit. |
