Dry Core, Aluminium Tape Screened, Steel Wire Armoured, LSZH Double Sheathed, Fibre Optic Cable


This cable is especially designed for harsh environments. The steel wire armour and the flame retardant zero halogen outer sheath make the cable suitable for installation under and above ground. Its UV stabilized low smoke zero halogen double sheath makes this cable flame retardant and relatively resistant to UV ,oil, water and nuclear radiation. This dry core cable employs dual-side copolymer coated aluminum tape and water tightness compound within loose tube to provide resilient and robust moisture protection to the fibre.

Fire Rating

  • IEC 60332-1, IEC 60332 - 24,IEC 61034-2,IEC 60754-1/2


  • Central strength member (CSM): glass fibre reinforced plastic material, LSZH covered if needed.
  • Tube: thermoplastic material containing up to 12 single mode optical fibres and filled with a suitable water tightness compound.
  • Stranding:The required numbers of elements (tubes or fillers) are SZ stranded around the central strength member.

Ordering Information
TF10020 SERIES FO Cable part numbers are made up using the table below. The part number always starts with the letters TF10020 to denote that it is a TF10020 SERIES FO Cable. This is followed by 3 numbers which symbolises the core quantity and then 2 letters to denote the fibre type. Example of a TF10020 SERIES FO Cable part number: TF10020048M1 The above example describes an OM1 (62.5um, Orange Sheath) TF10020 SERIES FO Cable, with 48 cores.
