K209B LSZH Armoured Optical Fiber Cables
Application
K209B LSZH Armoured Optical Fiber 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 fi bers 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.
