ADSS optical cable model

ADSS optical cable models are identified based on fiber count, mechanical design, span length, voltage rating, and environmental suitability. Key Parameters for Model Identification1.

Fiber Count and Type ADS

S cables are available in a wide range of fiber counts, typically from 12 to 432 fibers, using single-mode or multimode fibers. Fiber types include ITU-T G. 652D single-mode, 50/125 µm or 62.

5/125 µm multimode, and non-zero dispersion-shifted fibers. The fiber arrangement can be in loose buffer tubes or ribbon configurations for high-density applications. 2.

Mechanical Design and Strength Members ADS

S cables are all-dielectric, meaning they contain no metallic components. Strength is provided by aramid yarns or glass fiber reinforced plastic (GRP) rods. Some models feature double jackets for enhanced protection against UV, wind, and ice loads.

The design ensures the cable can support itself over spans up to 700 meters or more, depending on the model. 3. Span Length and Sag Performance The installation span is a critical factor.

Longer spans require higher tensile strength and sag control. Manufacturers provide torque-balanced designs and options like gel-filled or gel-free buffer tubes to maintain fiber integrity over long spans. 4.

Voltage Rating and Environmental Conditions ADS

S cables installed near high-voltage lines must have tracking-resistant jackets. Voltage classes typically range from less than 69 kV to over 500 kV, and the outer sheath material (HDPE or track-resistant polyethylene) is selected based on UV exposure, temperature extremes, and moisture conditions. 5.

Manufacturer-

Specific Model Codes Manufacturers like AFL and Prysmian use structured codes to identify models. For example, AFL-ADSS codes include fiber count, fiber type, span length, and NESC loading condition. Prysmian uses FlexTube® micromodules, aramid yarns, and GRP central members, with specifications for maximum installation tension (MIT), maximum allowable tension (MAT), and thermal elongation coefficient (CTE).

Practical Steps for Identification

Determine the fiber count and type required for your network. Assess the installation environment, including span length, voltage, wind, ice, and UV exposure. Check mechanical requirements, such as tensile strength and sag tolerance.

Refer to manufacturer datasheets for model codes that match your specifications. For example, ADSS-12J, ADSS-24F, or ADSS-48F indicate fiber count and configuration. Verify compliance with standards like ITU-T G.

652D for fibers and NESC loading for aerial installations. By combining these parameters, you can accurately identify the appropriate ADSS optical cable model for your project, ensuring both mechanical reliability and optical performance.
