OKB-… optical cables are designed for laying in soils of all categories, except those subject to freezing deformation, in cable ducts, along bridges and ramps. Cable with a double layer of armored wires - in soils of all categories, at the intersection of navigable rivers and water barriers. The thickness of the outer cable sheath is not less than 2.0 mm.
Cables brand OK (N) B ...
Hydrophobic cable fillers do not have a dropping at 70 ° C.
The electrical resistance of the outer sheath of the cable, measured between the patron and the environment, when recalculated to 20 ° C is not less than 2000 MΩ · km (for cables in the performance that does not propagate burning, not less than 1000 MΩ · km).
The outer sheath of the cable withstands a test voltage of 20 kV DC or 10 kV AC at 50 Hz for 5 seconds.
The service life of the cables, including the storage period, is not less than 25 years if the instructions for installation and operation are observed and in the absence of effects exceeding the above specified.
The storage period for cables in the supplier’s packaging in heated premises may be 15 years. When stored in the field under a shed - 10 years. Shelf life is included in cable life.
The warranty period of the cables is 2 years from the date of commissioning. The warranty period is calculated from the date of commissioning, but no later than 6 months from the date of cable sales by the manufacturer.

Cables can be laid manually or mechanized at a temperature
not lower than minus 10 ° C. Minimum temperature for cable cutting and installation should not be below minus 10 ° C.
When laying and installing cables, the permissible tensile, crushing, impact and bending loads must not be exceeded. Cutting and cable installation should be carried out by methods and tools that prevent its damage.
The static bending radius of the cable during installation, installation and operation can be at least 20 cable diameters. For cables intended for installation into cable ducts, during installation, a bending radius of 250 mm is allowed.
The radius of the bend of the installation can be at least 3 mm (within 10 minutes) during installation.
The static bending radius of the OM must be at least 20 diameters of the OM.
Cable installation should be made using couplings, clips and other accessories that have a certificate or declaration of conformity. It is recommended to coordinate the technical characteristics of the fitting with the cable manufacturer.
