ABSTRACT:
A device for connecting a peripheral unit to an optical bus-line which comprises a substrate onto which are integrated a first optical waveguide for being inserted in the path of the bus-line, a second optical waveguide for being connected to the emitting circuit of the peripheral unit, a third optical waveguide for being connected to the receiving circuit of the peripheral unit, and three couplers for intercoupling these waveguides. A plurality of connections related to the peripheral unit are provided for controlling the couplers in order to control the emission or the reception of information on or from the bus-line.
