ADSS Fiber Optic Cable: Lightweight and Self-Supporting
ADSS (All-Dielectric Self-Supporting) fiber optic cable is designed for aerial deployment without the need for additional support or messenger wires. Its lightweight construction and robust design, incorporating aramid yarn reinforcement, make it ideal for various applications, offering a cost-effective alternative to OPGW cables.
Overview
ADSS cable gets its name from its all-dielectric and self-supporting nature. It’s constructed with a fiber core, aramid yarn for strength, and an outer sheath for protection. The absence of metallic components makes it suitable for high-voltage environments. For long spans or installations near power lines, double sheathing or anti-tracking (AT) sheathing is often employed.
Applications
ADSS fiber optic cable is commonly used for:
- Backbone network aerial installations
- Distribution for FTTH (Fiber to the Home) networks
Features
- Metal-free construction.
- Aramid yarn reinforcement provides high tensile strength and self-supporting capabilities.
- Single or double sheathing offers excellent insulation and fiber protection.
- Small diameter and lightweight design simplifies construction and reduces costs.
