PCT No. PCT/FR93/01006 Sec. 371 Date Jun. 3, 1994 Sec. 102(e) Date Jun. 3, 1994 PCT Filed Oct. 9, 1992 PCT Pub. No. WO94/09602 PCT Pub. Date Apr. 28, 1994.On the input side of the matrix, a set of emitters (E1,1, . . . , Em,n) receive data to be transmitted via the matrix. The set of emitters emit waves carrying the data at controlled wavelengths. A set of filters (F1,1, . . . , Fn,m) transmit the waves at the output of the matrix selectively as a function of the wavelengths of the waves. The waves are transmitted from the emitters to the filters firstly via a group of switching distributors (X1, . . . , Xm), each of which is capable of connecting each of its inputs to each of its outputs on command, and secondly via a group of star distributors (C1, . . . , Cn), each of which permanently connects all of its inputs to all of its outputs. A particular application of the invention is to a telecommunications network when a data collection operation is to be performed simply.
