FIELD: electricity.
SUBSTANCE: in symmetric four-pair cable comprised of cable cores in polymer insulation with outer polymer shell each pair is placed into a metallopolymeric band with metal facing outside and overlapped edges along the whole cable length, and between screened pairs there are screened optical modules of open type with overlapped edges along the whole cable length and metal facing outside and placement of cross-shaped power element in their structure, moreover the above module contains optic fibre in each slot, at that symmetric screened pairs and open modules in the same layer are twisted around the central screened optic module of closed type, with metal facing outside, reinforced with cross-shaped power element with optic fibre in each slot of this module. All screens of symmetric pairs and optical modules of open and closed type are made of metallopolymeric band, with metal facing outside, thus ensuring contact with drain conductor and bimetal band laid on top of the layer of symmetric pairs and open optical modules, metal braid and outer polymer shell.
EFFECT: reducing mutual influence between pairs.
