An optical ring mesh network includes a plurality of optical rings, each of which is coupled to at least one other ring by a respective optical coupler. The rings are provided with a plurality of input/output nodes constituted by optical couplers. The nodes are so positioned, and are of such a number, that the optical path length between any given pair of nodes includes n couplers where n is less than the number of nodes.
