SELF-ISOLATING DESIGN OF A RIVER OPTICAL COMMUNICATION CABLE Russian patent published in 2019 - IPC H01B11/22 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used in the construction of optical communication cables in the construction of fiber-optic communication lines along the river bed and crossings over rivers and lakes. Disclosed is an optical communication cable comprising optical fibers, each pair of which is placed in a reinforced optical module with two reinforcing elements. All reinforced modules are located around central power element in ecological hydrophobic aggregate, water-blocking tape and in polymer tube, metal shell around which insulated metal wires are laid. Outer polymer shell of high-pressure polyethylene is perforated along the entire length of the cable.

EFFECT: as a result of using the proposed structure, in case of an emergency, on one of the regeneration sections, temporary power may be provided through a wire-wire system along the shore cable with a common self-contained power supply system of regenerators of the FO regenerators in the cable.
