GYFTY53 Steel Tape Armored Non-metallic Strength Member Direct Buried Fiber Optic Cable

GYFTY53 Steel Tape Armored Non-metallic Strength Member Direct Buried Fiber Optic Cable

Product Overview:

GYFTY53 is an outdoor communication fiber optic cable characterized by a non-metallic strength member, a loose tube stranding and filling structure, double polyethylene (PE) bonded sheath, and corrugated steel tape armoring.

Detailed Structure of GYFTY53 Direct Burial Armored Fiber Optic Cable:

GYFTY53 cable structure follows a "layered protection" design, from the inner optical fiber to the outer jacket, ensuring both signal integrity and environmental resistance.

Features of GYFTY53 Underground Direct Buried Optical Fiber Cable:

(1) Superior Water and Moisture Resistance

• Loose tubes filled with water-blocking gel prevent moisture from penetrating the fiber surface.

• Water-blocking compounds in the cable core block longitudinal water seepage.

• The double-sided laminated steel tape and PE sheaths form a tight moisture barrier. This ensures the cable remains functional even in waterlogged soil or high-humidity areas.

  
  

(2) Excellent Mechanical Performance

• Tensile Strength: The central FRP rod enables the cable to withstand a short-term tensile force of up to 3000N and a long-term tensile force of 1000N, suitable for pulling during burial construction.

• Lateral Pressure Resistance: The corrugated steel tape armoring layer can resist a lateral pressure of 3000N/100mm, preventing cable deformation or fiber damage caused by soil compaction or heavy loads above the burial path.

• Bending Flexibility: The loose tube structure and non-metallic reinforcement allow a static bending radius of 12.5 times the cable diameter and a dynamic bending radius of 25 times the cable diameter. This facilitates installation in narrow spaces or along curved paths.

• Rodent & Animal Resistance: Steel tape armor is hard enough to prevent gnawing by rodents (e.g., moles, rats) or burrowing animals—an essential feature for underground cables in rural or suburban areas.

  
  

(3) Lightning and Corrosion Resistance

• Lightning Protection: The non-metallic strength member avoids forming a "lightning conductor," significantly reducing the risk of cable damage or signal interruption caused by lightning strikes in thunderstorm-prone regions (e.g., mountainous areas, open fields).

• Corrosion Resistance: The double-sided laminated steel tape (isolated from soil by PE coating) and MDPE outer sheath resist corrosion from acidic/alkaline soil, salt spray (coastal areas), and chemical pollutants, ensuring long-term reliability.

  
  

(4) Wide Temperature Adaptability

• The cable operates stably within a temperature range of -40℃ to +70℃. It can withstand extreme cold (e.g., northern winter) and high heat (e.g., southern summer), without performance degradation from material expansion/contraction.
  
  

(5) Long Service Life

• Strict control over raw materials (high-quality FRP, PBT, PE) and manufacturing processes (precision extrusion, uniform armoring) ensures the cable has a design service life of 25 years, reducing long-term maintenance and replacement costs for network operators.

Applications:

GYFTY53 cable is primarily designed for direct burial laying and is widely used in telecommunications, broadband access, and industrial communication networks, especially in scenarios requiring high reliability and environmental adaptability:

(1) Long-distance Telecommunication Backbones

• It is used in long-haul fiber optic networks (e.g., inter-city or provincial communication lines) that require direct burial to avoid occupying above-ground space (e.g., across farmlands, deserts, or mountainous areas). Its low signal attenuation and stable mechanical performance ensure long-distance (tens to hundreds of kilometers) high-speed data transmission.

(2) Inter-office Communication Connections

• It connects telecommunications offices, data centers, or base stations in urban or suburban areas. Direct burial avoids the need for expensive pipeline construction, reducing project costs while ensuring stable communication between core network nodes.

  
  

(3) Lightning-prone Areas

• Ideal for installation in regions with high lightning activity, such as mountainous areas, open plains, or rural areas. Its non-metallic structure eliminates lightning-induced damage, ensuring uninterrupted service for rural broadband, emergency communication, or power grid communication (where lightning is a major risk).

(4) Urban and Suburban Broadband Access

• Used in "last-mile" broadband networks (e.g., Fiber-to-the-Home, FTTH) to connect central offices to residential communities or commercial areas. Direct burial under roads or green spaces avoids disrupting existing infrastructure (e.g., roads, buildings) and supports high-bandwidth services like 5G, 4K video streaming, and cloud computing.

(5) Industrial and Special Environments

Applied in industrial parks, mining areas, or coastal regions:

• Industrial Parks: Resists mechanical vibration and chemical corrosion, connecting industrial control systems and monitoring devices.

• Coastal Areas: The corrosion-resistant outer sheath and steel tape withstand salt spray, suitable for coastal communication networks.

• Mining Areas: Withstands heavy loads and moisture, supporting communication between mining sites and control centers.
