OKTBg central tube armored fiber optic cable for directly burial, duct, pipes, blocks
OKTBg central tube armored fiber optic cable for directly burial
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. Central tube filling – thixotropic gel.
3. Central tube – polyethyleneterphtalat (PBT).
4. Strength member: two steel wires placed longitudinally.
5. Water blocking layer – thixotropic gel.
6. Armoring - corrugated laminated steel tape.
7. Outer sheath – polyethylene (HDPE).
Design versions:
1. Multimode Fibers acc. ITU-T G.651.1; IEC 60793-2-10.
2. With the power elements - glass-fiber.
3. Outer sheath:
- low smoking;
- halogen-free;
- flame retardant compound (LSZH).
