Choosing the wrong aerial fiber cable can increase project costs and shorten network life. Many operators face a common question: should they use ADSS or a Self-supporting Figure 8 Aerial Fiber Cable?
Both options serve outdoor aerial networks, yet they differ in design, installation, and performance. In this article, you will learn the key differences, advantages, costs, and best applications of each solution so you can make a confident decision.
● ADSS and Self-supporting FIG8 Aerial Fiber Cable are two leading solutions for aerial fiber deployment.
● ADSS uses a fully dielectric structure and works well near power transmission lines.
● A Self-supporting Figure 8 Fiber Cable includes an integrated messenger wire for mechanical support.
● Figure-8 designs usually offer lower installation costs for telecom networks.
● ADSS often performs better in high-voltage environments where metallic components are undesirable.
● Armored Figure-8 cables provide strong resistance against impact, moisture, and harsh weather.
● Installation methods, span requirements, route conditions, and project budgets should guide cable selection.
● Neither cable is universally superior; the best choice depends on the specific deployment scenario.
When comparing these two cable types, the biggest difference lies in how they support themselves between poles. ADSS relies on internal strength members, while a Self-supporting Figure 8 Aerial Fiber Cable uses an integrated messenger wire attached directly to the cable body.

ADSS stands for All-Dielectric Self-Supporting cable. It contains no metallic components. Instead, it uses aramid yarns and dielectric materials to withstand tensile loads.
A Self-supporting Figure 8 Aerial Fiber Cable features a distinctive figure-8 profile. One section contains the optical fibers, while the other contains a steel messenger wire that provides support.
ADSS distributes mechanical stress through high-strength aramid yarns. These fibers carry tension throughout the cable structure.
In contrast, a Figure-8 cable transfers most tensile forces to the messenger wire. This design reduces stress on the optical fiber unit and improves stability during aerial installation.
ADSS installation generally requires suspension clamps, dead-end fittings, and specialized hardware designed for dielectric cables.
Figure-8 cables often require fewer accessories. Installers can directly secure the messenger wire to poles, simplifying deployment.
ADSS is frequently used along power transmission and distribution routes.
A Self-supporting Figure 8 Aerial Fiber Cable is commonly used in telecom access networks, broadband expansion projects, and rural communication systems.
Both cable types handle wind and ice loads effectively when properly engineered.
ADSS can support medium to long spans. Figure-8 cables also perform well over long distances due to the strength of the messenger wire.
In many telecom projects, Figure-8 cables offer lower overall project costs. The integrated support system reduces installation time and hardware expenses.
ADSS often carries a higher initial cost due to its advanced dielectric materials and specialized accessories.
Choose ADSS when cables must operate near high-voltage power infrastructure.
Choose a Self-supporting Figure 8 Aerial Fiber Cable when seeking cost-effective deployment in telecom or broadband networks.
Note: Cable selection should consider both installation environment and long-term maintenance costs.
The internal structure of a cable directly affects durability, installation efficiency, and network reliability.
ADSS is a fully dielectric aerial cable designed for self-supporting installation. It contains optical fibers protected by loose tubes, water-blocking materials, and aramid yarn strength members.
Because it contains no metal, ADSS is highly resistant to electrical interference.
A Self-supporting Figure 8 Aerial Fiber Cable combines optical fibers and a messenger wire into one integrated structure.
The messenger wire provides support, eliminating the need for separate suspension wires. This design simplifies construction and reduces labor requirements.
The main difference is the strength system.
ADSS uses non-metallic aramid yarn reinforcement.
Figure-8 cables rely on galvanized steel messenger wires that offer excellent tensile performance and long-term stability.
Many Figure-8 aerial cables include protective layers designed for harsh outdoor environments.
Common protection methods include:
● Steel tape armoring for crush resistance
● Aluminum moisture barriers
● UV-resistant outer jackets
● Water-blocking compounds
These features improve reliability in demanding installations.
Tip: Projects in rural or forested areas often benefit from armored cable designs because they offer better protection against external damage.
Installation efficiency can significantly affect project budgets and deployment schedules.
ADSS installations typically require trained personnel and specialized fittings.
A Self-supporting Figure 8 Aerial Fiber Cable usually allows faster installation because the messenger wire is already integrated into the cable structure.
ADSS performs exceptionally well on utility-owned power poles.
Figure-8 cables fit easily into telecom pole networks where standard attachment methods are already available.
Labor expenses can represent a substantial portion of network deployment budgets.
Because Figure-8 cables require fewer installation steps, many contractors report shorter construction times.
Example data (requires verification): Some field projects report labor savings of 15%–30% compared with more complex aerial installations.
Routine inspections are straightforward for both cable types.
However, Figure-8 messenger systems often allow technicians to visually inspect support components quickly during maintenance operations.
Note: Always evaluate local weather conditions before selecting aerial installation hardware.
Outdoor fiber networks must withstand years of environmental stress.
Strong winds and ice accumulation create significant tension on aerial cables.
ADSS cables resist these forces through internal strength members.
Figure-8 cables rely on messenger wire support, which can provide excellent mechanical stability in severe weather.
Sag affects network appearance and safety.
The messenger wire in a Self-supporting Figure 8 Aerial Fiber Cable helps maintain stable tension over long spans.
ADSS cables also perform well but require precise engineering calculations to control sag.
Modern aerial cables use multiple moisture protection technologies.
These may include:
● Water-blocking yarns
● Gel-filled loose tubes
● Moisture barriers
● Sealed cable jackets
These systems help prevent water ingress and fiber degradation.
Both cable types operate across wide temperature ranges.
Quality outdoor cables remain reliable during hot summers, freezing winters, and rapid temperature changes.
Tip: Select cable jackets designed for local climate conditions to maximize service life.
Many telecom operators prefer Figure-8 designs because they balance performance and affordability.
The integrated messenger wire reduces the need for additional support hardware.
This design often lowers overall project expenses.
Armored versions offer strong resistance against crushing, impacts, and accidental damage.
These characteristics make them suitable for challenging outdoor environments.

This contributes to stable network performance and reduced maintenance requirements.
Manufacturers offer various configurations to meet different project requirements.
Options may include:
● Steel tape armored structures
● Aluminum moisture barriers
● Compact lightweight designs
● Different fiber counts
Note: Figure-8 cables are especially popular for broadband expansion projects where budget efficiency is a priority.
