2. Central tube filling – thixotropic gel.
3. Central tube – polyethyleneterphtalat (PBT).
4. Outer sheath – polyethylene (HDPE).
5. Strength messenger - steel rope or wire.
Design Versions:
1. Multimode Fibers acc. ITU-T G.651.1; IEC 60793-2-10.
2. Remote strength member - fiber reinforced plastic.
3. Outer sheath:
- low smoking;
- halogen-free;
- flame retardant compound (LSZH).
