K209B LSZH Armoured Optical Fiber Cables

K209B LSZH Armoured Optical Fiber Cables

Application

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 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.
