K209B LSZH Armoured Optical Fiber Cables

 

Applications :

  • The cables are designed for long distance telecommunication and using optical fibres in urban railways infrastructure. These low smoke halogen-free cables are laid on hooks, pulled through ducts or cable trays.

Standards :

  • RATP K209B or RATP K209A
 

 

Construction :

  • Compact Tube: 6 or 12 singlemode optical fibres G652 or multimode fibers assembled under thermoplastic “peelable” skin. Tube diameter: 1mm.
  • Filling : Water-swelling yarns.
  • Tube : Thermoplastic.
  • Peripheral Strength Member : Water-swelling glass yarns.
  • Armour : Corrugated steel tape armour 25/100.
  • Sheath : LSZH.

Optional :

  • K209A Type : For K209A type, the cables have loose tubes with 6-12 fi bers, steel wire strand as central strength member, glass yarn reinforced, incorporating a corrugated steel tape armour and an outer UV stabilized LSZH jacket.
