Stranded Loose Tube Armored Fiber Optic Cable – Direct Buried

The 250μm fibers are positioned in a loose tube made of a high modulus plastic.The tubes are filled with a water-resistant filling compound.A steel wire,sometimes sheathed with polyethylene(PE)for cable with high fiber count,locates in the center of core as a metallic strength member.Tubes and possible fillers are stranded around the strength member into a compact and circular cable core.The cable core is filled with the filling compound to protect it from water ingress,over which a thin PE inner sheath is applied.After the plastic coated steel tape is longitudinally applied over the inner sheath,the cable is sheathed by PE material.

Stranded Loose Tube Armored Fiber Optic Cable – Direct Buried

Premium Outdoor Connectivity & Ultimate Protection

The GYTY53 Armored Fiber Optic Cable is engineered for high-demand communication infrastructures. Whether you are setting up long-distance telecommunications or local interoffice networks, this cable provides the structural integrity needed for direct burial and harsh outdoor conditions. Featuring a robust corrugated steel tape armor, it offers unparalleled protection against moisture, mechanical pressure, and rodents.


Key Features

  • Heavy-Duty Armoring: Double-sheathed with a corrugated steel tape layer for superior crush resistance and rodent protection, making it ideal for direct burial without additional conduit.
  • High-Modulus Loose Tube Design: Contains $250 \mu m$ fibers protected by a high-modulus plastic tube filled with a water-resistant compound to prevent signal degradation.
  • Metallic Strength Member: A solid steel wire center provides high tensile strength, ensuring the cable remains stable during long-span installations.
  • Extreme Weather Resilience: Rated for a wide operating temperature range from -40°C to +70°C, ensuring reliable performance in both freezing and scorching environments.
  • Superior Moisture Barrier: Utilizing a specialized fiber ointment and filling compound to prevent water ingress, ensuring long-term reliability in damp soil.
