Non-Metallic Outdoor GYFTY Cable

Product Introduction

The GYFTY optical cable represents a highly reliable, non-metallic loose tube stranded solution engineered specifically for demanding outdoor trunk and access networks. Manufactured to strictly comply with IEC 60794-1 and YD/T 901-2009 international telecommunication standards, this cable ensures full compliance and smooth acceptance for large-scale infrastructure projects. At its core, it houses 24 vividly colored G.652D single-mode fibers. Each fiber is delicately positioned within a premium PBT loose tube, which is thoroughly filled with a specialized viscous water-blocking gel to prevent moisture ingress. These tubes and accompanying fillers are precisely stranded around a central Fiber Reinforced Plastic (FRP) strength member. Because it is completely devoid of metal components, this architecture forms a compact, circular core that is exceptionally safe for deployment along high-voltage power lines, railway communication grids, and thunderstorm-prone regions. Encased in a rugged polyethylene (PE) outer sheath, the exterior feels smooth yet highly resilient, offering formidable defense against ultraviolet exposure and damp environments. Designed for extreme durability, it delivers a long-term tensile strength of 500 N and a short-term capacity of 1000 N, paired with a crush resistance of 1000 N/10cm. Functioning flawlessly across a broad temperature spectrum from -40°C to +70°C, this GYFTY cable serves as the optimal choice for versatile deployments, including duct routing, aerial suspension, and direct burial installations in harsh industrial landscapes.

Product Advantage

1. Resilient Loose Tube Construction with Water-Blocking Protection

Each vividly colored G.652D single-mode fiber is carefully positioned inside a high-modulus Polybutylene Terephthalate (PBT) loose tube, which is completely flooded with a specialized, viscous water-blocking gel. This precise internal architecture effectively isolates the delicate optical fibers from external mechanical stresses and prevents any moisture ingress. The dense gel acts as an impenetrable barrier, halting water migration along the tube's length, thereby guaranteeing consistent signal transmission even in high-humidity climates, heavy rainfall regions, or fully submerged underground environments. Furthermore, this loose tube configuration provides ample spatial clearance, allowing the fibers to move freely. This internal mobility minimizes signal attenuation that typically occurs during cable bending, twisting, or pulling. Before leaving the facility, these components endure rigorous dynamic bending and torsion tests to ensure long-lasting operational stability under physical strain.

2. Non-Metallic Central Strength Member for Lightning Safety

At the core of this GYFTY cable lies a rigid Fiber Reinforced Plastic (FRP) strength member, rendering the entire structural composition completely non-metallic. By eliminating all metallic elements, the design inherently neutralizes the risk of lightning strikes and severe electrical interference. This makes the cable an exceptionally secure choice for aerial deployments alongside high-voltage power transmission lines, railway communication networks, and geographical zones prone to frequent thunderstorms. Beyond its electrical insulation properties, the FRP central member delivers outstanding tensile strength while keeping the overall cable remarkably lightweight and highly flexible. This lightweight profile significantly reduces the physical burden on installation crews, dropping labor costs and simplifying the overhead deployment process across challenging terrains.

3. Compact Stranded Core with High Fiber Density

The PBT loose tubes and accompanying solid fillers are systematically stranded around the central FRP member to construct a highly compact, perfectly circular cable core. This geometrically optimized design maximizes internal fiber density, successfully housing 24 fibers within a relatively slender overall diameter without compromising physical integrity. The stranded configuration plays a critical role in evenly distributing pulling forces and lateral crushing weights across the entire cable structure, significantly enhancing structural resilience during long-span aerial installations. While this specific model is equipped with 24 colored fibers, the underlying stranded architecture serves as a versatile foundation. It supports extensive customization options, allowing project managers to request tailored configurations ranging from 2 up to 192 cores in either single-mode or multi-mode variations to match exact network capacity requirements.

4. Durable PE Outer Sheath for Outdoor Environments

The exterior of the cable is encased in a thick, black polyethylene (PE) outer sheath that feels smooth to the touch yet provides a formidable defensive layer against harsh environmental factors. This specialized PE jacket offers exceptional resistance to prolonged ultraviolet (UV) radiation, severe moisture, and drastic temperature fluctuations. During manufacturing, the sheath material undergoes intense quality control testing, including prolonged exposure to UV chambers, oil immersion, and flame retardancy evaluations. When deployed in direct burial or underground duct applications, this rugged exterior acts as a primary shield against abrasive chemicals, heavy soil compression, and destructive rodent bites. It ensures the internal fibers remain pristine and fully functional across a wide operating temperature range from -40°C to +70°C, adapting effortlessly to diverse and extreme climatic conditions.

5. Excellent Mechanical Strength for Demanding Installations

Engineered specifically to endure high-tension pulling and heavy lateral compression, this optical cable easily withstands significant mechanical stress during both the initial deployment phase and its extended service life. The synergistic combination of the rigid FRP central strength member, the flexible stranded loose tubes, and the resilient PE outer jacket delivers superior tensile and crush performance metrics. Installers can confidently pull the cable through complex duct systems or suspend it across long aerial spans without fearing structural deformation. This exceptional physical endurance makes the GYFTY cable an indispensable asset for constructing reliable backbone networks, expansive FTTX distribution grids, and long-haul telecommunications infrastructures where environmental resilience and minimal maintenance are absolute priorities.
