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.
