FIELD: electricity.
SUBSTANCE: in symmetric four-pair cable containing conductors in polymeric isolation with external polymeric shell, each pair is placed into metal-polymeric tape with the metal part facing outside with overlapping of edges along the whole length of the cable, and between the screened pairs the screened open optical modules with overlapping of edges are placed along the whole length of the cable metal outside with placement in their structure of the crosswise power element providing stiffness of the open module and containing optical fibres in each window of this module, meanwhile the symmetric screened pairs and open modules in one lay are twisted around the screened central optical module of the closed type with the metal part facing outside which is also strengthened by a crosswise strength element with optical fibres in each window of this module, and all screens of symmetric pairs and optical modules of open and close type are made from the metal-polymeric tape with metal part facing outside, providing contact with the drain conductor and applied above the lay of screened symmetric pairs and open optical modules of bimetallic tape, metal braid and external polymeric shell.
EFFECT: invention allows to reduce mutual influence between the pairs.
