OKLBg armored fiber optic cable for burial, ducts, and pipes
OKLBg armored fiber optic cable for burial, ducts, and pipes
Application:
Cable is designed for installation in cable ducts, pipes, blocks, directly in the soils of all categories, including the area with corrosion activity and the territories infected with rodents except subjected to deformations, as well as through swamps, lakes, unfloatable and non-navigable rivers up to 15 meters deep.
Cable design
1. Optical fibers acc. ITU-T G.652 D / G.657A1.
2. Loose Tubes – PBT (polybutylene terephthalate).
3. Core filling – thixotropic gel.
4. Fillers (if applicable).
5. Central strength member (fiber reinforced plastic).
6. Fastening winding of yarns and tapes.
7. Inner sheath – polyethylene (if applicable).
8. Peripheral strength member – aramid yarns (if applicable).
9. Armouring - corrugated laminated steel tape.
10. 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:
- low smoking;
- halogen-free
- flame retardant compound (LSZH).
