FIELD: radio-frequency cables.
SUBSTANCE: invention relates to designs of radio-frequency cables capable of transmitting two independent spatially spaced data streams on one coaxial pair, one of flows due to cable design and application conditions is confidential. Cable has an internal conductor made as single-mode or multimode optical fiber in form of a double-layer quartz thread consisting of a core and a shell coated with a layer of copper above the quartz shell, insulation, an external conductor and a shell. One information stream is provided by transmission over a coaxial pair of signals in the radio-frequency band, the second information stream is carried out by optical signals over the optical fiber.
EFFECT: invention will make it possible to organize cable system of confidential communication for large business structures, which allows to avoid unauthorized access to confidential information and to prevent industrial espionage.
