Features and Benefits
- Central Loose Tube: thermoplastic material (PBT), containing optical fibers and filled with a suitable water tightness jelly compound.
- Peripheral Strength Elements: aramid yarns.
- Longitudinal water tightness : Water blocking element used for eliminates the need for traditional flooding compound and provides efficient and craft-friendly cable preparation.
- Ripcord:Nylon thread or Aramid yarn for easily stripping of the sheath." vspace="6">
- Outer Sheath: (Option)
Polyethylene sheath
LSZH polyethylene sheath: Low Smoke Zero Halogen sheath for Flame retardant characteristics.
