Manufacturer s bend-insensitive fiber ADSS

Bend-insensitive ADSS fiber optic cables combine all-dielectric self-supporting design with fibers engineered to tolerate tight bends, enabling reliable aerial installation along power lines.

Overview of ADS

S CablesADSS (All-Dielectric Self-Supporting) cables are non-metallic fiber optic cables designed to support their own weight between utility poles or towers without requiring messenger wires or metallic support. They are suitable for high-voltage environments because they contain no conductive elements, reducing the risk of electrical interference.

ADS

S cables are commonly used in aerial installations for both distribution and transmission networks, including live-line installations.

Bend-

Insensitive Fiber TechnologyBend-insensitive fibers are designed to minimize signal loss when the fiber is bent around tight radii, which is critical for aerial and compact installations. This is achieved by incorporating an optical trench or a ring of lower refractive index material around the core, reflecting light back into the core and reducing bending losses. Bend-insensitive fibers are available in both single-mode (G.

652/G. 655) and multimode variants, making them compatible with ADSS cable designs.

Manufacturer Options

Several manufacturers produce ADSS cables with bend-insensitive fibers: AFL: Offers AFL-ADSS® and Flex-Span ADSS cables, using aramid yarns for strength and elongation, suitable for long spans and live-line installations. Their portfolio supports a wide range of fiber counts and span lengths. Prysmian Group: Provides Long Span ADSS cables with up to 288 fibers, designed for high-voltage lines up to 75 kV, with optional track-resistant jackets to prevent dry-band arcing.

Abptel: Manufactures ADSS cables in China with capacities up to 144 fibers, supporting both single-mode and multimode fibers, and includes suspension hardware and termination components for robust aerial networks. Yiba Cable: Produces G652D single-mode ADSS cables with double PE jackets for spans up to 1000 meters, suitable for aerial installations.

Key Features

Fiber Types: Single-mode (G. 652/G. 655) and multimode, including bend-insensitive variants.

Fiber Counts: Typically 2–288 fibers per cable, with designs like 24 fibers per tube for high-count cables. Environmental Tolerance: Resistant to wind, ice, and temperature variations; optional anti-tracking jackets for high-voltage lines. Installation: Supports long spans without additional support; compatible with live-line installation techniques.

ApplicationsBend-insensitive ADSS cables are ideal for: Aerial fiber networks along power distribution and transmission lines. Urban or constrained environments where tight bends are unavoidable. High-voltage corridors requiring non-conductive, self-supporting cables.

Long-span installations where mechanical tension and environmental loads are significant. By combining bend-insensitive fibers with the self-supporting ADSS design, these cables provide reliable, low-loss performance even in challenging aerial and high-voltage environments.
