Abstract
The device enables bi-directional optical communication between a master module and slave modules by means of an optical rod (1) made of transparent material. The master module is axially coupled to the rod. The modules are arranged laterally along a useful part of the rod bounded by a lateral reflector located opposite the slave modules. The lateral reflector can be formed by a plurality of adjacent notches (12) formed at the surface of the rod and constituting a continuous reflecting zone in the form of serrated teeth, and/or by a narrow reflecting strip (17). The slave modules can be positioned anywhere along the useful part of the rod and their lateral location is not critical, a lateral coupling zone extending over at least 1 cm outside the rod. Such a device can be advantageously used in an electrical panel.
