FZOVDMU-SD is a stranded cable with even 432 fibres. It is suitable for direct buried and duct installation. The fibres are protected by polymer coated corrugated steel tape.

This type is also known as A-DQ(ZN)SR2Y (VDE 0888).


  • Optical fibres: Coloured single-mode fibres according to the ITU-T G.652.D standard.

  • Secondary coating: Jelly filled loose tubes made of thermoplastic polyester.

  • Fillers: Plastic fillers when applicable.

  • Central strength member: Glass fibre reinforced plastic (FRP).

  • Cable core stranding: The secondary coating tubes and fillers (when needed) are SZ-stranded around the central strength member. 192 fibre cable has two stranding layers.

  • Wrapping: The cable core is wrapped longitudinally with a swellable tape.

  • Rip cord: Non-metallic rip cord is applied under the sheathing layers.

  • Protection: Polymer coated corrugated steel tape applied longitudinally with an overlap. The nominal thickness of the steel tape is 0,15 mm.

  • Outer sheath: UV resistant black HDPE. Nominal sheath thickness is 1,8 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.
