What are the types of ADSS optical cables

Fiber optic splice closure knowledge brief Published 22 Oct 2020

Prepared for preliminary research by the RIVO OPTICAL knowledge desk. Confirm cable count, splice capacity, sealing class, tray layout, protection sleeves and installation requirements against current standards and product documentation.

ADSS optical cables come in several types, including standard, aramid-reinforced, armored, double-jacketed, and gel-filled or dry-core variants, each designed for specific environmental and mechanical requirements.Standard ADSS Cable

Standard ADSS cables are the basic type, designed for aerial installation without metallic support. They are lightweight, self-supporting, and suitable for short to medium spans, typically carrying low to medium fiber counts (12–48 cores) while maintaining dielectric properties for high-voltage environments .

Aramid-Reinforced ADSS

These cables include aramid yarn layers (e.g., Kevlar) to enhance tensile strength, allowing longer spans and better resistance to wind and ice loads. The aramid reinforcement surrounds the central tube or core, providing self-supporting capability without metallic elements .

Armored ADSS

Armored ADSS cables incorporate a metallic or additional protective layer to safeguard against mechanical damage, rodents, or harsh environmental conditions. While still dielectric in design, the armor adds durability for aggressive installation environments .

Double-Jacketed ADSS

Double-jacketed cables feature two protective layers, often woven or polymer-based, to improve UV resistance, abrasion protection, and environmental durability. This type is ideal for areas with high exposure to sunlight or mechanical wear .

Gel-Filled or Dry-Core ADSS

To prevent moisture ingress, ADSS cables may have gel-filled cores or dry water-blocking elements. Gel-filled designs provide continuous moisture protection, while dry-core variants use water-blocking tapes or powders, ensuring fiber integrity over long-term outdoor deployment .

Multi-Tube ADSS

Multi-tube ADSS cables contain multiple buffer tubes within a single jacket, allowing higher fiber counts and efficient use of space. This design is suitable for high-density data transmission and long-distance aerial or underground applications .

Core Count Variations

ADSS cables are available with fiber counts ranging from 2 to over 864 fibers, depending on project requirements. Higher core counts increase data capacity but also affect cable size, weight, and cost, making selection dependent on network design, future expansion, and budget considerations .

Structural Designs

ADSS cables are generally manufactured in two main structural designs:

  • Central Tube Design: Compact and cost-effective, ideal for short to medium spans with low to medium fiber counts.
  • Layered Twist Design: Optimized for longer spans and higher fiber counts, providing enhanced mechanical stability and load distribution . These types and designs allow ADSS cables to be tailored for high-voltage transmission lines, telecom networks, cable TV distribution, railway and roadway communications, and renewable energy projects, ensuring reliable performance in diverse aerial environments .

All-dielectric self-supporting cable

OverviewConstruction detailsAccessories and installationApplication issues

All-dielectric self-supporting (ADSS) cable is a type of optical fiber cable that is strong enough to support itself between structures without using conductive metal elements. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission lines and often sharing the same support structures as the electrical conductors. ADSS is an alternative to OPGW and OPAC with lower installation cost. The cables are designed to be s
