What is ADSS Fiber Optic Cable?

ADSS stands for All Die-Electric Self Supporting cable. The self-supporting means, this types of fiber cable doesn’t need any metallic supporting wire. And the die-electric means an insulator.

Since this ADSS fiber doesn’t need any running wire to support it, it has been widely used in outdoor environment. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission lines.

What Is ADSS Cable?

ADSS cable is a type of fiber optic cable that is strong enough to support itself between structures without containing conductive metal elements. Both single mode and multimode fibers can be arranged in ADSS cables with a maximum of 144 fibers. ADSS fiber optic cable is designed for outside plant aerial and duct applications in local and campus network loop architectures from pole-to-building to town-to-town installations. The cabling system that includes cables, suspension, dead-end, and termination enclosures offers a comprehensive transmission circuit infrastructure with high-reliability performance.

Types of ADSS fiber cable

a)     Central Tube Structure

In a central tube design, the fibers are placed in a PBT loose tube filled with water-blocking material within a certain length. Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer that is used as an insulator in the electrical and electronics industries.

Then they are wrapped with aramid yarn (heat-resistant and strong synthetic fibers) according to the desired tensile strength and extruded with PE (≤110KV electric field strength) or AT (≥100KV electric field strength) sheath. The PE is Polyethylene (PE), widely used thermoplastic polymer for fabricated parts and components. This structure features with small diameter and light weight but has limited lengths.

a)     Stranded Structure

The fiber loose tubes are surrounding around a central strength member (usually as FRP material). Fiber-reinforced polymer (FRP), also Fiber-reinforced plastic, is a composite material made of a polymer matrix reinforced with fibers. The fibers are usually glass, carbon, or aramid, although other fibers such as paper or wood or asbestos have been sometimes used.

And the rest parts are similar to the central tube structure. This type is able to obtain a longer fiber length. Although the diameter and weight are relatively big, it is better to be deployed for large span applications.


ADSS cable is ideal for installation in distribution as well as transmission environments. Since the ADSS cables provide an optimal solution for a broader combination of fiber counts and span lengths, more and more aerial cabling system designers tend to adopt them for telecommunications, like power utilities, telcos, and private network groups. Combining convenience and cost-effectiveness, an aerial fiber-optic deployment requires this kind of fiber optic cables for better performance

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
