Armored Non-metallic Stranded Loose Tube Duct Fiber Cable

GYFTA armored duct cable is an outdoor fiber optic cable designed without metal armor, utilizing FRP as the central reinforcement bond. It offers excellent water and moisture resistance, as well as non-conductivity, thanks to the corrugated laminated aluminum tape covering the loose tube. Due to these properties, GYFTA non-metallic fiber optic cables are commonly installed on rooftops, pipelines, and similar environments. Depending on the number of users requiring access, Bonelinks can manufacture GYFTA stranded loose tube fiber optic cables with a minimum of 2 cores and a maximum of 300 cores.

Armored Non-metallic Stranded Loose Tube Fiber Cable: Reliable Outdoor Connectivity at its Best

GYFTA fiber cables stand as the ultimate solution for outdoor installations, delivering unmatched reliability and performance in challenging environments. With their innovative features, including gel-filled loose tubes and aluminum tape armor, GYFTA cables provide superior resistance against moisture, water penetration, and mechanical strains. These non-metallic fiber optic cables find their niche in aerial, duct, and direct burial deployments, ensuring optimal fiber protection and uncompromising connectivity. From harsh conditions to non-conductive surroundings, GYFTA cables empower outdoor fiber optic networks with unwavering dependability and flexibility. Experience peace of mind and seamless performance with GYFTA cables, designed to conquer the toughest outdoor applications.


  • Gel-Filled Loose Tubes: GYFTA cables employ gel-filled loose tubes to house individual optical fibers. This gel filling acts as a barrier against moisture and water infiltration, making GYFTA cables particularly suitable for outdoor and harsh environments where water damage is a concern.
  • Aluminum Tape Armor: GYFTA cables feature an additional layer of aluminum tape armor. This armor provides robust mechanical protection, safeguarding the cable against external factors such as impact, rodents, and environmental hazards. The aluminum tape armor enhances the cable’s durability, ensuring reliable performance even over long distances.
  • Outdoor Versatility: GYFTA cables are designed specifically for outdoor installations, including aerial, duct, and direct burial applications. Their construction and protective layers enable them to withstand challenging environmental conditions, such as temperature fluctuations, moisture, and UV radiation.
  • Flexibility in Installation: Despite incorporating an armor layer, GYFTA cables maintain a certain level of flexibility. This flexibility facilitates easier installation and maneuverability during deployment, especially when encountering bends or challenging pathways.


UV resistance; Waterproof; Moisture-proof


  • Aerial Installations: GYFTA cables are often used for aerial installations, where the cables are suspended between poles or towers. The aluminum tape armor provides mechanical protection, ensuring the cables can withstand environmental factors such as wind, ice, and temperature fluctuations.
  • Duct Installations: GYFTA cables are suitable for installation in underground ducts or conduits. The gel-filled loose tubes offer excellent moisture resistance, protecting the fibers from water ingress. The aluminum tape armor enhances the cable’s durability, making it suitable for the rigors of buried installations.
  • Direct Burial: GYFTA cables can be directly buried in the ground without additional protection. The gel filling and aluminum tape armor provide resistance to moisture, rodents, and physical damage, making them well-suited for outdoor burial applications.
  • Harsh Environments: GYFTA cables excel in harsh environments such as industrial areas, coastal regions, or areas with extreme weather conditions. The gel-filled loose tubes and aluminum tape armor offer enhanced protection against moisture, UV radiation, and mechanical stresses, ensuring reliable performance in challenging surroundings.
  • Non-Conductive Environments: The non-conductive nature of GYFTA cables, thanks to the aluminum tape armor, makes them suitable for environments where electrical conductivity is a concern. They can be safely deployed on rooftops, near power lines, or in areas where electrical interference needs to be minimized.
