Product Description

Outdoor Direct Burial Fiber Optic Armoured Cable GYTA53 GYTS53 Direct Buried Single Mode

Outdoor Direct Burial Fiber Optic Armoured Cable GYTA53 GYTS53 Direct Buried Single Mode


Outdoor Fiber Optic Armoured Cable


Product Description:

       GYTA53 uses metal strength member as central strength member to provide excellent strain performance of the cable. Double-jacket structure provide the cable nice properties of moisture resistance and crush resistance. Double armor structure provides cable good property of rodent-resistance. High strength loose tube is hydrolysis resistant. A layer of water-blocking material is applied around the cable core to prevent water ingress. It can be used for duct and direct buried application, suitable for harsh environments.



      1. Good mechanical and temperature performance
      2. High strength loose tube that is hydrolysis resistant
      3. Special tube filling compound ensures a critical protection of fiber
      4. Crush resistance and flexibility
      5. The following measures are taken to ensure the cable watertight:
           a. Steel wire used as the central strength member
           b. Loose tube filling compound
           c. 100% cable core filling
           d. APL moisture barrier
           e. Water-blocking material


Cable design:

  • 24 SM-fibers.
  •    6 SM-fibers placed in each tube.
  • Steel wire as central strength member.
  • Loose buffer tubes SZ-stranded.
  •    The buffered tube filled with filling compound while the stranded core covered with water block material.
  •    Aluminum tape as the moisture barrier.
  •    PE Cable inner sheath.
  •    Corrugated stainless steel tape armored.
  •    HDPE Cable Outer sheath.
  • Suitable as: Direct-buried installation.
