Armored fiber-optic cable OKLK
Application:
The cable is designed for use under increased requirements for resistance to mechanical impacts during installation by manual and/or mechanized methods directly in soils of all categories, including areas with high corrosion aggressiveness and territories infested with rodents, in regions with loose soils and soil shifts, except those subject to permafrost deformations, as well as across swamps, lakes, floating and navigable rivers with depths of up to 50 meters.
Cable design:
1. Central strength member (fiber reinforced plastic).
2. Optical fibers acc. ITU-T G.652 D / G.657A1.
3. Loose Tubes – PBT (polybutylene terephthalate).
4. Fillers (if present).
5. Core filling – thixotropic gel.
6. Binding tape (wrapping).
7. Inner sheath – polyethylene (HDPE).
8. Armouring – round galvanized steel wires.
9. Outer sheath – polyethylene (HDPE).
Design versions:
1. Water-blocking tapes and yarns (“dry” core).
2. Multimode Fibers acc. ITU-T G.651.1; IEC 60793-2-10.
3. Central strength member: steel cord or wire.
4. Outer sheath:
- PVC;
- flame retardant compound (LSZH).
