ADSS (All Dielectric Self-Supporting) optical cables with G.652 fiber are designed for aerial installations, offering high mechanical strength, environmental resistance, and long-term reliability.

Key Features

Fiber Type and Structure: These cables use G.652.D single-mode fibers, suitable for long-distance transmission with low attenuation and minimal dispersion . Loose tubes are typically made of PBT plastic, filled with water-blocking gel, and SZ-stranded around a dielectric central strength member (CSM), often reinforced with aramid yarns for tensile strength . Cable Jacket and Protection: The outer sheath is usually black HDPE or double PE jacket, providing resistance against UV radiation, abrasion, fungus, and environmental stress. Some models include anti-tracking additives for enhanced electrical insulation . Mechanical and Environmental Performance: ADSS cables are designed for self-supporting aerial installation without metallic components, capable of withstanding wind speeds up to 25 m/s, ice loads, and high-voltage proximity (up to 110 kV in some models), . They are tested for crush, impact, and tensile strength, ensuring durability under typical service conditions . Span and Fiber Count Options: Standard spans range from 120 m to 500 m, depending on environmental conditions, and fiber counts typically range from 6 to 144 fibers, allowing flexibility for network design . Installation Advantages: No messenger wire is required, and the SZ-stranded loose tube design with ripcords allows easy mid-span access. The dielectric CSM eliminates the need for grounding or bonding .

Warranty and Reliability

While most ADSS G.652 cables are designed for long-term service life of up to 25 years, a three-year warranty can often be provided by manufacturers or distributors, covering defects in materials and workmanship. It is recommended to confirm warranty terms with the supplier before purchase .

Applications

• Overhead aerial fiber deployment along power lines or poles
• Long-distance backbone networks
• Urban and rural broadband distribution
• Environments requiring high tensile strength and environmental resistance ADSS G.652 cables with a three-year warranty provide a robust, low-maintenance solution for aerial fiber optic networks, combining mechanical durability, environmental protection, and reliable optical performance.
