Abstract
The invention pertains to an optical switch matrix comprising n input channels, branching means for dividing the input channels up into p branched channels, merging means for merging the p branched channels into m output channels, and optical fibers for connecting the output channels of the branching means with the input channels of the merging means, wherein n, m, and p are natural numbers greater than or equal to 2, and wherein the branching means, the fibers, and the merging means are each attached to a separate substrate or a separate group of substrates. The optical switching matrix according to the invention is very compact and allows efficient use of the materials available for the manufacture thereof.
