Outdoor fiber optic networks can be installed in different ways depending on the terrain, infrastructure and network design.
The three most common deployment methods are aerial installation on poles, underground duct installation and direct burial installation. Each method requires a specific fiber cable structure designed for the environment.
Aerial Fiber Cable Installation
Aerial fiber cables are installed on utility poles and suspended between pole structures. This installation method is widely used in rural networks, power line communication systems and backbone fiber routes.
- Lower installation cost compared to underground construction
- Faster deployment
- Suitable for long-distance routes
Common Cable Type for Aerial Installation
ADSS fiber cables are commonly used for aerial installations because they can be installed on utility poles without metallic support elements.
Duct Fiber Cable Installation
Duct fiber cables are installed inside underground conduits that provide mechanical protection from soil pressure and external impacts.
- Better environmental protection
- Suitable for urban infrastructure
- Easier cable replacement and maintenance
Common Duct Fiber Cable Structures
Typical duct cables include aluminum tape armored fiber cables and steel tape armored fiber cables designed to resist moisture and mechanical stress.
Direct Burial Fiber Cable Installation
Direct burial fiber cables are installed directly underground without protective conduits. These cables require reinforced structures to withstand soil pressure, moisture and external impact.
- Suitable for long underground routes
- No duct infrastructure required
- Higher mechanical protection required
Typical Direct Burial Fiber Cable
Direct burial fiber cables such as armored double sheath cables are commonly used in long-distance underground routes.
Comparing Aerial, Duct and Direct Burial Fiber Installation
- Aerial installation is faster and lower cost but exposed to environmental conditions.
- Duct installation provides better protection and easier maintenance.
- Direct burial installation is used where duct infrastructure is not available.
FAQ
What fiber cable is used for aerial installation?
ADSS fiber cables are commonly used for aerial installations because they can be deployed on utility poles without metallic support structures.
