  2. Cable core:
    • For low fibre counts (up to 96): central steel tube with polyethylene sheath
    • For fibre counts up to 384: up to 8 steel tubes stranded together, water-blocking filling compound, polyethylene inner sheath
  3. Strength member: one or two layers of steel wires over the cable cable core
  4. Outer sheath: polyethylene
