Optical switching matrix

Abstract

Abstract At the input of this matrix a set of transmitters (E1, 1...Em, n) receives information to be transmitted through it. It transmits waves carrying this information, on controlled wavelengths. A set of filters (F1, 1...Fn, m) transmits these waves at the output of the matrix selectively according to their wavelengths. From these transmitters to these filters, these waves are transmitted first of all by a group of switching distributors (X1...Xm) each able to connect each of its inputs to each of its outputs, on command, then by a group of star-wired distributors (C1...Cn) each permanently connecting all its inputs to all its outputs. This invention finds an application especially in a telecommunications network when an information collection operation has to be able to be carried out simply. <IMAGE>
