FZ4RMU Flex is a fibre optic cable with a flexible construction. The fibres are housed in small and thin walled loose tubes made of soft elastomeric material and therefore fibre tubes can be bended significantly more than traditional PBT loose tubes. The cable construction itself is non-metallic but still strong enough to be installed directly to the ground by digging or ploughing e.g. together with a power electric cable.

Construction 

• Optical fibres (12-96F): Coloured single-mode fibres according to the ITU-T G.652.D. Fibre coating diameter 250 μm.
• Optical fibres (192F): Coloured single-mode fibres according to the ITU-T G.657.A1. Fibre coating diameter 200 μm. 
• Secondary coating: Flexible colour coded fibre modules. Fibres are housed in thin walled tubes made of soft elastomeric material. 
• Wrapping: Water blocking tape. 
• Strength members: Four glass fibre reinforced plastic rods (FRP) in the sheath. Rod nominal diameter 1,6 mm. 
• Outer sheat:h UV resistant black polyethylene compound (HDPE). Nominal sheath thickness is 2,6 mm. Minimum sheath thickness is 2,3 mm, from wire to outer surface 0,3 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.
