FIELD: electricity.
SUBSTANCE: design of optical cable contains optical fibres, C-form module, main reinforcing device in this module, additional strengthening device in the external polymeric coating, water-blocking band and two cords, breaking an outer shell, located symmetrically to each other, while C-form module is designed with overlapping of one top by another, water-blocking band is located along the whole length of external section of C-form module with overlapping of edges differing by that in front of cords, breaking outer shell, two-pair structures symmetric cable each placed in a polymeric perforated band, separating each pair from another.
EFFECT: invention allows to decrease the time for elimination of FOCL damage and to protect from moisture penetration.
