Direct Burial Fiber Optic Cable Stranded Loose Tube Armored Cable

GYFTY53 Direct burial armored fiber cable is an outdoor fiber optic cable with double PE jacket and corrugated steel and aluminum tape wrapping structure. The dual PE sheath is designed to increase the wear resistance of the cable and enhance the protection of the internal structure, the corrugated steel tape is wrapped to enhance the stiffness of the cable and prevent excessive bending, and the aluminum tape is wrapped to prevent water and moisture as a barrier. Therefore, GYFTY53 fiber optic cable is commonly used for access section direct burial, pre-set and radiation of wet environment.


  • Good mechanical and temperature performance.
  • High strength loose tube that is hydrolysis resistant.
  • Special tube filling compound ensures critical protection of fiber.
  • APL moisture barrier
  • PSP enhancing moisture proof
  • Water-blocking material for underground application
  • Crush resistance and flexibility for direct buried construction
  • Two parallel steel wires ensure tensile strength
  • Small diameter, lightweight and friendly installation
  • Long delivery length
