ABSTRACT:
The architecture concerns a bus (BCM) incorporating magnetic coupling. The bus is structured in sections (S.sub.i-1, S.sub.i). The "coupler" elements (Bi) are disassociated from the "cable" elements (C.sub.b,i-1, C.sub.b,i) of the bus (B.sub.CM). The couplers (B.sub.i) themselves comprise a magnetic coupling module (1), constituted by passive elements, and an interface module (2) incorporating electronic interface circuits between the magnetic coupling module (1) and the subscribers (U.sub.i) by means of supplementary cables (C.sub.a,i). According to a first variant, the modules (1, 2) consist of single casings (10, 20) used as is or placed in a cascade configuration. According to a second embodiment, the modules are multiple and are placed in casings containing rectangular connectors for interconnection between casings.
