CT2242 Outdoor Single Mode Armoured Trackside Optical Fiber Cables
Applications :
- The cables are designed for long distance telecom links on optical fibres along railway tracks. The cables are suitable for installation directly in channels or buried.
Standards :
- SNCF CT 2242.6.1
Construction :
- Fibres : Singlemode optical fibres G652 coloured (6 or 12 per tube).
- Central Strength Member : Non-metallic central reinforcement (FRP).
- Tube : PBT polyester tubes containing fibres.
- Filling : Petroleum jelly with water-swelling yarns to provide longitudinal watertightness.
- Inner Sheath : Low density polyethylene.
- Armour : 0.25mm thick corrugated steel tape armour.
- Outer Sheath : Low density polyethylene.
