Copper telecommunication ducted cable (FSP-JF-LAP)


Copper telecommunication ducted cables (FSP-JF-LAP) are used for primary and secondary distribution networks, (i.e., in the secondary network between cross-connection cabinets and the subscribers’ connections, in the primary network between the exchange and cross-connection cabinets) and produced for ducted underground installation with black PE sheath it is suitable for tropical environmental conditions (from -10 °C to +60 °C).


  • Up to 200 pairs following REA – PE 89 (USA), TCVN 8238:2009, IEC 60708
  • Conductor size: 0.4mm; 0.5mm; 0.65mm; 0.9mm.
  • Copper telecommunication ducted cables (FO) type is designed by solid pure annealed copper conductor, high density polyethylene foam skin or solid (skin) insulated, paired, ten or twenty-five pairs sub-unit type, jelly filled, polyester tape wrapped (PS tape), screened with aluminum moisture barrier and black polyethylene sheathed, ducted type, primary and secondary local telephone cable.
