GYXTW53 Central Unitube Double Steel Tape Armored Underground Direct Buried Fiber Optic Cable

GYXTW53 Central Unitube Double Steel Tape Armored Double Sheathed Underground Direct Buried Fiber Optic Cable 

Description:

• Double Steel Tape Armor: Double Corrugated Steel Tape (CST) provide superior mechanical protection against side crush, impact, and rodent bites.

• 2 Parallel Steel Wires Strength Member: Provides high tensile resistance

• Central Unitube: Single Loose Tube filled with water-blocking gel, good protection for the fibers, this structure makes smaller size, light weight, esay installation.

Detailed Structure of GYXTW53 Armored Fiber Cable:

The fibers are placed in a loose tube made of PBT which is filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP (steel tape) longitudinally. Between the PSP and the loose tube water -blocking material is applied to keep the cable compact and waterproof. Two parallel steel wires are placed at both sides of the steel tape,over which a thin PE inner sheath is applied. After the second PSP is longitudinally applied over the inner sheath,finally the cable is completed with a PE outer sheath.

Features of GYXTW53 Fiber Optic Cable:

• Superior Mechanical Protection: The double steel tape armor and dual sheaths offer high resistance to crush, impact, and tensile forces, suitable for direct burial without additional ducting.

• Excellent Moisture and Corrosion Resistance: Water-blocking gel, water-blocking yarn or tape, and dual PE/LSZH sheaths effectively prevent moisture penetration and resist corrosion from soil, salt, and chemicals.

• Rodent and Termite Resistance: The rigid steel tape armor acts as a physical barrier against gnawing damage from rodents and termites, which is critical for underground deployment in rural or forested areas.

• Low Attenuation and Stable Performance: The central loose tube structure minimizes microbending loss, ensuring consistent optical transmission even under environmental stress (temperature variation, soil settlement).

• Easy Installation: Light weight compared to traditional heavy armored cables, it supports direct burial, trench laying, and horizontal directional drilling (HDD) installation methods.

• Environmental Compliance: LSZH sheath options meet flame-retardant and low-toxicity requirements for applications in environmentally sensitive areas.

Applications:

• Underground Direct Burial Networks: Primary application for long-haul backbone networks, urban access networks, and rural broadband projects, where cables are buried directly in trenches without duct protection.

• Harsh Environmental Deployment: Suitable for areas with rocky soil, high soil pressure, or corrosive soil conditions (e.g., coastal regions, industrial zones with chemical contamination).

• Rural and Remote Area Connectivity: Ideal for connecting remote villages, farms, and industrial sites where duct installation is costly or impractical.

• Municipal and Utility Networks: Compatible with infrastructure projects such as smart city deployments, traffic monitoring systems, and power utility communication links.
