Opelink manufactures high-quality outdoor fiber optic cables designed for harsh environmental conditions and long-distance telecommunications applications. With 13+ years of experience in optical cable manufacturing, we provide reliable solutions for telecom operators, utility companies, and network infrastructure projects worldwide.
Outdoor fiber optic cable is specifically engineered to withstand environmental challenges including UV radiation, temperature extremes, moisture, and physical stress. These cables form the backbone of telecommunications networks, connecting cities, data centers, and remote locations across diverse terrain.
Opelink offers a comprehensive range of outdoor cables including loose tube designs (GYTA, GYTS), double-armored cables (GYTA53) for direct burial, and aerial self-supporting cables (ADSS). All our outdoor cables feature water-blocking technology, UV-resistant jackets, and optional armoring for rodent protection.

Applications
• Telecommunications Backbone: Long-distance fiber routes between cities and regions • Utility Networks: Power company communication networks • Railway Systems: Trackside communication and signaling • Highway Networks: Traffic monitoring and toll collection systems • Oil and Gas: Pipeline monitoring and communication • Wind Farms: Turbine connectivity and SCADA systems • Rural Broadband: Connecting remote communities • Campus Networks: Inter-building connections in universities and industrial parks
Installation Methods
.Aerial Installation: Cables are suspended between poles using messenger wires (for GYTA/GYTS) or self-supported (ADSS). ADSS cables are designed to withstand wind and ice loading without additional support structures. .Duct Installation: Cables are pulled through underground ducts using cable pulling equipment. GYTA and GYTS cables are ideal for duct installations due to their flexibility and durability. .Direct Burial: GYTA53 double-armored cables are buried directly in trenches without additional conduit. The double steel tape armor provides protection against ground shifting, rocks, and rodent damage. .Microduct Installation: Specialized microcables are blown through small-diameter microducts using compressed air, allowing for high fiber density in limited space.
FAQ
Q1: What is the difference between GYTA and GYTS outdoor cables?
A: The main difference is the armor type. GYTA uses aluminum tape armor, which provides good protection against moisture and moderate physical stress. GYTS uses corrugated steel tape armor, offering superior crush resistance and rodent protection. GYTS is preferred for direct burial and harsh environments, while GYTA is suitable for duct and aerial installations where weight is a concern.
Q2: When should I use ADSS cable versus GYTA/GYTS with messenger wire?
A: Use ADSS (All-Dielectric Self-Supporting) when you want to avoid metallic components - it's immune to lightning and can be installed on power line towers without electrical isolation. ADSS uses aramid yarn for strength and supports span lengths up to 1000m. Use GYTA/GYTS with messenger wire for shorter spans or when cost is a primary concern.
Q3: How deep should outdoor fiber optic cable be buried?
A: Direct burial cables (GYTA53) should typically be buried 24-36 inches (60-90cm) deep, depending on local regulations and soil conditions. In areas with heavy vehicle traffic or frost lines, deeper burial may be required. Always check local codes and mark cable routes clearly to prevent accidental damage during excavation.
Q4: What is the maximum pulling tension for outdoor fiber optic cables?
A: Maximum pulling tension varies by cable type and fiber count. Generally: GYTA/GYTS - 600N to 2700N depending on fiber count; ADSS - varies by span length and wind/ice loading design. Never exceed the manufacturer's specified maximum tension, and use proper cable grips and pulling equipment. Maintain a minimum bend radius of 20x cable diameter during installation.
Q5: Do you provide cable installation accessories and technical support?
A: Yes, Opelink provides a complete range of installation accessories including cable grips, pulling eyes, splice closures, and termination boxes. We offer technical support including installation guidelines, training materials, and on-site assistance for large projects.
