AERIAL CABLE

  • Overview
  • Specifications
  • Features & Benifits

PTCL Cables offer Aerial Fig-8 Optical Fiber Cables. These are Self-Supporting cables designed for aerial installation. The cable design provides easy and economical one-step installation and stable performance over a wide temperature range. The whole tensile load is borne by steel messenger wire. These cables are manufactured according to international standard and these cables fully conform to Pakistan Telecommunication Company Standard Specification TR-109 as applicable in Pakistan.

Applications:

     Aerial Installation – High Mechanical Strength - Data, Voice & Video Transmission       

      

Cable Constructions:      

      Loose Tube filled with Gel - Stranded around Central Strength Member - Water Blocking Material - Dry Core – Corrugated Steel Tape - Messenger Wire embedded Polyethylene Outer Jacket

Technical Characteristics

  • The unique extruding technology provides the fibers in the tube with good flexibility and bending endurance
  • The unique fiber excess length control method provides the cable with excellent mechanical and environmental properties
  • Multiple water blocking material filling provides dual water blocking function
  • Provides good crush resistance
