FYOHBMUK is a cable with self-supporting figure-8 construction. The maximum span length of the cable is 60 metres. The fibres of FYOHBMUK are in a plastic core tube and the cable is protected by a longitudinally applied polymer coated aluminium tape. The suspension wire is made of steel wires.


  • Optical fibres: Coloured single-mode fibres according to the ITU-T G.652.D standard.
  • Secondary coating: A plastic core tube with jelly filling.
  • Wrapping: The cable core is wrapped longitudinally with a swellable tape.
  • Moisture barrier: Polymer coated aluminium tape applied longitudinally with an overlap. The nominal thickness of the tape is 0,15 mm.
  • Suspension wire: The suspension wire is made of stranded galvanised steel wires. The nominal diameter is 7x1,57 mm.
  • Outer sheath: The cable sheath consists of UV resistant black PE. Nominal sheath thickness is 1,4 mm. Nominal neck dimensions: height 3,0 mm, width 2,1 mm.
  • Sheath marking: Marking printed on the sheath at one meter interval: Nestor Cables - cable type - lot number - year of manufacture - length marking.
