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.
