ADSS Fiber Optic Cable: Lightweight and Self-Supporting for Aerial Deployments
ADSS (All-Dielectric Self-Supporting) cable is a lightweight, robust, and cost-effective fiber optic solution designed for aerial deployments. Hone ADSS fiber optic cable eliminates the need for additional hanging lines, simplifying installation and reducing costs. This makes it ideal for various applications, from backbone networks to FTTH distribution.
Description
ADSS cable is specifically engineered for aerial installation without requiring conductive metal elements. Its lightweight nature and aramid yarn reinforcement ensure sufficient strength for self-support between poles or towers. This design presents a compelling alternative to OPGW cables, offering lower installation expenses.
The cable structure typically comprises a fiber core, aramid yarn for reinforcement, and an outer sheath. For extended spans or proximity to power lines, double sheathing or an AT (anti-tracking) sheath is recommended.
Applications
ADSS cable is widely used for:
- Aerial and self-supporting backbone networks
- Distribution for FTTH (Fiber-to-the-Home) networks
Features
- Metal-free construction, eliminating conductivity concerns.
- Aramid yarn providing high tensile strength and self-supporting capability.
- Single or double sheathing offering superior insulation and protection for the optical fibers.
- Small diameter and lightweight design for easy and economical deployment.
