ABSTRACT OF THE DISCLOSURE A matrix-type optical concentrator - distributor. It comprises a matrix of retractable light deflection members, whereof the m lines and k columns (respectively 1 remaining columns) are optically connected to m and k transmitters - receivers (respectively 1 transmitters) of light signals to form two submatrixes having respectively k x m and 1 x m of said members. Preferably, the k x m members permit the passage of the incident signals from the transmitters and in part those from the transmitters - receivers and the 1 x m members permit the partial passage of the incident signals from the 1 transmitters and the m transmitters - receivers. This leads to bidirectional communication between the m and k transmitters - receivers and unidirectional communicat- ions from the 1 transmitters to the m transmitters - receivers, optically managed by the means intercepting a transmitted part of the signals. Application to optical telecommunications. Figure 1. B 7123/7240 C/PV
