Optical Fiber Cables - DUCT TYPE

Single Mode Non-Metallic Dry Core Duct Type Optical Fiber Cables, the construction of the non-metallic cables begins with our proven loose tube design. The loose tube provides protection against environment and mechanical forces. This is a light weight cable with smaller diameter and suitable enough for duct and conduit use. These cables are manufactured according to international standard.

APPLICATIONS

  • Inter Office Trunking, Data, Video Transmission, Control / Alarm System
  • Light Weight and Flexible
  • Laying in Ducts and Concrete

 

CABLE CONSTRUCTION

  • Loose Tube filled with Gel
  • Stranded around Central Strength Member
  • Water Blocking Material
  • Peripheral Strength Members
  • 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
