Outdoor shielded optical cables include armored, GYTA/GYTS loose tube, GYTA33 heavy armored, ADSS, and Figure-8 self-supporting models, covering 2–288 fiber cores for aerial, duct, and direct-burial applications.

Major Outdoor Shielded Cable Models

1. Armored Loose Tube Cables (GYTA/GYTS)
   • Features: Steel wire or steel tape armor, water-blocking gel or swellable tape, crush and rodent protection, UV-resistant PE jacket.
   • Applications: Direct-burial, duct, and aerial installations.
   • Fiber Count: Typically 2–288 cores.
   • Advantages: High mechanical protection, moisture resistance, suitable for harsh outdoor environments .
2. Heavy Armored Cables (GYTA33)
   • Features: Extra-thick steel armor for extreme mechanical stress, water-blocking design, UV and temperature resistance.
   • Applications: Direct-burial in high-risk areas, long-haul backbone networks.
   • Fiber Count: 2–288 cores.
   • Advantages: Maximum protection against rodents, crushing, and environmental hazards .
3. All-Dielectric Self-Supporting (ADSS) Cables
   • Features: No metallic components, self-supporting for aerial spans, designed to withstand wind and ice loads.
   • Applications: Power line corridors, aerial telecom installations.
   • Fiber Count: Varies, typically 2–144 cores.
   • Advantages: Safe near electrical lines, lightweight, controlled sag, efficient installation .
4. Figure-8 Self-Supporting Cables
   • Features: Integrated messenger strand for aerial support, loose tube or ribbon fiber construction, water-blocking and UV-resistant jacket.
   • Applications: Aerial installations without separate support wires.
   • Fiber Count: 2–144 cores.
   • Advantages: Simplifies aerial deployment, reduces installation hardware, maintains fiber integrity .
5. Ribbon Cables
   • Features: Multiple fibers bonded side-by-side in a flat ribbon, often with protective outer jacket.
   • Applications: High-density outdoor networks, FTTH, and inter-building links.
   • Fiber Count: Up to 12 fibers per ribbon, scalable to hundreds of fibers.
   • Advantages: Maximizes fiber density, reduces latency, simplifies splicing and management .
6. Micro Cables
   • Features: Ultra-compact loose tube design, 1–2 mm diameter, high fiber packing density.
   • Applications: Long-haul networks, FTTH, and congested conduit pathways.
   • Advantages: Lightweight, space-saving, easy installation in tight ducts .

Key Considerations for Shielded Outdoor Cables

• Environmental Durability: UV-resistant jackets, water-blocking, temperature endurance (-40°C to +70°C).
• Mechanical Protection: Steel armor, rodent protection, crush resistance.
• Installation Method: Direct-burial, aerial, duct, or building entry.
• Performance: Single-mode or multimode, low attenuation, high bandwidth.
• Customization: OEM/ODM options for fiber count, jacket material, and branding . These shielded outdoor optical cable models provide robust solutions for diverse deployment scenarios, ensuring reliable performance in harsh environmental conditions while supporting high-capacity fiber networks.
