MULTI-CHANNEL MULTI-CELL OPTOELECTRONIC SWITCHING NETWORKS FOR MULTI-SERVICE TELECOMMUNICATIONS SYSTEMS

摘要

Optoelectronic switching networks for multi-service wide-band telecommunications systems of the type comprising, on the one hand, a selector board (receiver or emitter) carrying a plurality of compound optoelectronic units (selector units) each of which includes 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 a plurality of optoelectronic units (conjugated units) optically conjugated with each compound unit of the selector board. With a view to reducing the number of selector units in order to achieve the advantages inherent in these reductions, the selection means of each selector unit are means for respectively connecting cells each of which is selected in a zone among a plurality of zones from the matrix to the links of a plurality of channel links attached to the said selector unit.
