Non-armored Outdoor Cable Central Tube

GYXY is an outdoor non-armored fiber optic cable with waterproof layer, built-in double parallel steel wire, single casing design, which is mainly used in the short overhead span distance, wet environments and low number of users crowded into the area. The single casing compact design allows the cable to accommodate a maximum of 24 fibers and a minimum of 2 fibers. For short overhead span requirements, Bonelinks is able to use double FRP glass fiber reinforcement instead of phosphorized steel wire to produce GYXY non-armored outdoor fiber optic cable, which not only saves project procurement cost, but also keeps the performance of fiber optic cable stable and achieves stable network transmission.


  • Good mechanical and temperature performance.
  • Two parallel steel wires ensure tensile strength.
  • High-strength loose tube that is hydrolysis resistant
  • Special tube filling compound ensure critical protection of fiber.
  • Small diameter, lightweight and friendly installation
