OKT unarmored fiber optic cable for several, ducts, pipes
Application
Cable is designed for installation in cable ducts, pipes, blocks under no danger of damage by rodents and possible long-term flooding. If a long-term flooding can happen, a polyethylene moisture barrier sheath should be used. In case of damage by rodents or upon direct installation into the ground the cable should be installed in protective plastic pipes.
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 – aramid yarns.
5. Outer sheath – polyethylene (HDPE).
Design Versions:
1. Multimode Fibers acc. ITU-T G.651.1; IEC 60793-2-10.
2. Strength members : glass yarns.
3. Outer sheath :
- low smoking;
- halogen-free;
- flame retardant compound (LSZH).
