Construction 

• Optical fibres: Single-mode fibres according to the ITU-T G.652.D.
• Secondary coating: Flexible colour coded fibre modules. Fibres are housed in thin walled tubes made of soft elastomeric material
• Water blocking: Water blocking yarns in the cable core.
• Strength members: Glass fibre reinforced plastic rods (FRP) in the sheath. Rod diameter 0,5 mm.
• Inner sheath: UV resistant black polyethylene compound (HDPE). Nominal sheath thickness is 1,5 mm..
• Strength members: A layer of E-glass yarns under the sheath for tensile strength and rodent protection.
• Outer sheath: UV resistant black polyethylene compound (HDPE). Nominal sheath thickness is 1,4 mm.
• Sheath marking: Marking printed on the sheath at one meter interval: Nestor Cables - cable type - lot number - year of manufacture - length marking

All of our fibre optic and copper cables are halogen-free.
