Abstract: The invention relates to a ring network being installed as bus network comprising: n≧4 nodes 200-1, . . . 200-5; and n−1 cable sections 100-1, . . . 100-5. Each of said cable sections includes a forward line 105-1 . . . 105-4 and a return line 110-1 . . . 110-4. The nodes except the first and the last node of said network are referred to as intermediate nodes. It is the object of the invention to improve such a network such that its total length is enlarged. This object is solved in the way that the network interfaces in said sequential arranged intermediate nodes 200-2 . . . 200-4 are connected alternately between two forward lines 105-1 . . . 105-4 or between two return lines 110-1 . . . 110-4 of the two cable sections being respectively connected to each of said intermediate nodes.
