Optical fiber cables

  • Optical fiber cablesTo serve complex signalling and telecommunications for train control, Nexans has developed MANs and LANs optical fiber cables, and is also an expert in GSM-R technology.
  • To meet the security concerns of tunnels and urban metro systems, we produce metal-armored and all-dielectric OF cables.


Lisbon’s intermodal Gare do Oriente uses Nexans optical-fiber-based LANs to coordinate rail, subway and surface transit, while an all-dielectric cable is used in the London Underground. Recent successes include the ongoing RATP contract (Paris), light rail for the Algiers suburbs, the Caracas subway, and tramways worldwide.
