FIELD: cables.
SUBSTANCE: invention relates to cable portion comprising databus line (54) having one or more subscriber lines (52) connected thereto by a coupler device. Each databus line and the subscriber line(s) each comprise a twisted pair of conductors protected by shielding. Coupler device comprises coupler (53) providing data transmission between the two parts of the databus line and between the databus line and the subscriber line(s), and connectors (56A, 56B, 58) serve to connect the databus line with the subscriber line(s) in reversible manner. Coupler device weighs less than 70 g and is held by means of a fastener collar that enables the cable portion to be put into place in particularly practical manner in order to constitute a data transmission circuit.
EFFECT: technical result is providing high quality of transmitted signals with the possibility of modular integration of data bus into data bus network.
