GMFU(Emergency Optical Cable)



Special Optical Cable

The loose tubes are made of high modulus plastics (PBT) and filled with a water resistant filling gel. Loose tubes are stranded around non-metallic central strength member (FRP). The cable core wrapped with a water blocking tape, and polyurethan (PU) is extruded as outer sheath.





  • Central strength member: metal materials available
  • Loose tube: PP or other materials available
  • Water blocking materials for loose tube: water blocking yarn available
  • Water blocking materials for cable core: cable filling compound available
  • Outer sheath: Aluminium tape armor, steel tape armor, anti-termite or flame retardant materials available






  • Small size, light weight, easy to handle
  • Superior bending and abrasion resistance performance
  • Field patch cord compatibility
  • Easy operate, easy deployment, can be used repeatedly
  • Wide application, reduce line interrupted time





  • Duct installation
  • Aerial installation
  • Direct-buried installation
  • Emergency repair
  • Temporarily connection
