ADSS fiber optic cables can be either single-mode or multimode, depending on the specific application and design.

ADSS (All-Dielectric Self-Supporting) cables are designed for aerial installation without metallic components, making them suitable for high-voltage and outdoor environments. They can house single-mode fibers (G.652D, G.657) for long-distance transmission or multimode fibers (OM1–OM5) for shorter-range applications . The fiber type is chosen based on the required transmission distance, bandwidth, and network design.

Fiber Types and Applications

• Single-Mode Fiber: Supports long-distance transmission, typically at 1310 nm or 1550 nm wavelengths, with unrepeatered distances up to 100 km. Ideal for backbone networks, intercity links, and high-speed telecom applications .
• Multimode Fiber: Includes OM1 to OM5 types, suitable for shorter distances such as campus networks, FTTH (Fiber to the Home), or data center connections. Multimode fibers allow multiple light modes but have shorter maximum transmission distances compared to single-mode .

Cable Structure

ADSS cables are available in central tube and stranded (multi-loose tube) designs. Both designs can accommodate single-mode or multimode fibers, with fiber counts ranging from 2 to 144 cores. The choice of structure depends on span length, tensile strength requirements, and installation environment .

Summary

ADSS cables are not limited to a single fiber type; they are versatile and can be configured with either single-mode or multimode fibers. The selection depends on the network's distance, bandwidth, and environmental requirements, making ADSS suitable for both long-haul and local aerial fiber deployments .
