OKL unarmoured fiber optic cable
OKL unarmoured fiber optic cable
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, 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. Fastening winding of yarns and tapes.
5. Central strength member (fiber reinforced plastic).
6. Fillers (if applicable).
7. Peripheral strength member – aramid yarns.
8. 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 rope or wire..
4. Outer sheath:
- low smoking;
- halogen-free
- flame retardant compound (LSZH).
