GYXTW Optical Cable Ideal for Outdoor Aerial Deployments

Selecting the appropriate outdoor aerial fiber optic cable can be challenging, particularly when ensuring stable signal transmission across diverse environmental conditions. The GYXTW cable, specifically designed for overhead installations, offers a reliable solution for outdoor network deployments.

The GYXTW cable, classified as a central tube optical cable, distinguishes itself through several technical merits:

• Enhanced Protection: Featuring a multi-layer structure including loose tubes, water-blocking gel, steel reinforcement, and polyethylene sheathing, it withstands moisture, extreme temperatures, and UV radiation.
• Mechanical Durability: Parallel steel wire reinforcement provides tensile strength up to 1500N (short-term) and crush resistance of 3000N/100mm (short-term), suitable for aerial installation stresses.
• Temperature Resilience: Operational range from -40°C to +70°C accommodates diverse climatic conditions.
• Installation Efficiency: Compact design (typically 1-12 fibers) and lightweight construction reduce deployment complexity.

The cable's architecture comprises seven critical components:

Utilizing ITU-T G.652.D single-mode fibers (250μm) with attenuation ≤0.35 dB/km at 1310nm, optimized for long-distance transmission.

High-modulus plastic tubes house individual fibers, allowing movement to mitigate mechanical stress.

Hydrophobic filler prevents longitudinal water penetration, maintaining ≤0.32 dB/km attenuation at 1383nm.

Dual parallel galvanized wires provide 800N long-term tensile strength with corrosion-resistant coating.

Black UV-resistant HDPE outer jacket (typically 2.0mm thickness) protects against environmental degradation.

Integrated steel-polymer composite enhances mechanical and moisture barriers.

Polyethylene-coated steel tape (0.15mm thickness) provides additional crush resistance (1000N/100mm long-term).

• Bend Radius: 10× cable diameter (static), 20× (dynamic)
• Dispersion: ≤3.5 ps/(nm·km) at 1288-1339nm
• Fiber Count: 1-12 cores with standardized color coding (blue/orange/green/brown for cores 1-4)
• Transmission Performance: ≤0.21 dB/km at 1550nm, meeting ITU-T G.652.D standards

• Long-haul backbone networks (inter-city connectivity)
• Metropolitan area networks (urban distribution)
• FTTx access networks (last-mile solutions)
• Rural broadband expansion projects
• Surveillance system backbones (CCTV transmission)

When specifying GYXTW cables, evaluate:

• Future-proof fiber counts (recommended minimum 20% spare capacity)
• Environmental exposure (wind zones, ice loading regions)
• Compliance with local telecommunications standards
• Third-party certification (UL, IEC, or regional equivalents)

The GYXTW cable's combination of mechanical robustness, environmental resistance, and transmission efficiency makes it a preferred choice for aerial fiber optic installations across varied geographic and climatic conditions.
