[0054] In a specific embodiment of the invention, the avionics 10a, 10b are modified so that a voltage can be superimposed on a signal on at least one electrical contact of the connector of the avionics 10, the optical communication bus 20 The terminal connector 30 should be connected to this electrical contact. The advantage is that the supply voltage is applied between the electrical contact of the connector considered by the avionics device 10 and the electrical ground of this connector, which is normally connected to the electrical ground of the device 10 . It is also possible to apply a voltage between two electrical contacts of the considered connector of the avionics 10 . Such a DC or quasi-DC voltage according to the frequency of the carrier signal of the information transmitted on the communication bus is undoubtedly of the nature of the digital signal transmitted and can be incorporated into the optical communication bus 20 directly via the internal power supply of t...
