ST2513/CT2243 Outdoor Single Mode Unarmoured 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 pulled through ducts or laid in channels.

Standards :

  • SNCF ST 2513-99
 

 

Construction :

  • Fibres : Singlemode optical fibres G652 coloured (6 or 12 per tube).
