Optical Fiber Cables - Non Metallic DIRECT BURIED

PTCL Cables offers Non-Metallic Direct Buried Optical Fiber Cables which also called anti-rodent has been popular cabling solution as its construction design helps to avoid Radio frequency interference and Electromagnetic interference, which is better for distribution in a minefield. Special Glass Yarn and a Robust Polyethylene Outer Jacket combine to deliver rugged durability and added rodent resistance. These cables are manufactured accordingto international standard.

APPLICATIONS

  • Direct Buried Installation with added advantage to
    avoid Radio Frequency and Electromagnetic
    Interference
  • Data, Video, Voice Transmission
  • Rodent Resistant

CABLE CONSTRUCTION

  • Loose Tube filled with Gel
  • Stranded around Central Strength Member
  • Water Blocking Material
  • Polyethylene Inner Sheath
  • Special Glass Yarn for Anti-Rodent and a Robust
    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
  • Special Glass Yarn for Anti-Rodent
  • Provides good crush resistance & tensile strength
