  • Characteristics
  • Parameter
    • lAccurate fiber excess length ensure a good performance of tensile strength and temperature

      lHigh strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fiber

      lThe following measures are taken to ensure the cable watertight:

      1) Steel wire as the central strength member

      2) Loose tube filling compound

      3) 100% cable core filling

      4) PSP enhancing moisture-proof
