ADSS (All-Dielectric Self-Supporting) fittings and OPGW (Optical Ground Wire) fittings serve distinct purposes in fiber optic networks:
1. Function & Installation
- ADSS Fittings:
- Designed for standalone all-dielectric cables (no metal components).
- Used in aerial installations(e.g., telecom poles) where electrical interference is a concern.
- Key hardware: Tension clamps, suspension clamps, vibration dampers
- OPGW Fittings:
- Built for composite cables (fiber + aluminum/steel wires) that double as ground wires for power lines.
- Installed on high-voltage transmission towers (e.g., 110kV+ grids).
- Key hardware: Dead-end assemblies, splice boxes, armor rods.
2. Material & Durability
- ADSS: Aluminum alloy clamps with UV-resistant coatings** (no conductivity needed).
-OPGW:Galvanized steel/aluminum fittings with lightning protection(200kA+ withstand capacity).
3. Common Applications
- ADSS: Urban fiber networks, railway communications.
- OPGW: Power utility grids, substation monitoring.

When selecting ADSS hardware for high-wind areas, prioritize aerodynamic aluminum alloy clamps (ASTM B221), Stockbridge-type vibration dampers, and galvanized dead-ends rated for 150–200 km/h winds. Ensure compliance with IEC 61396 standards, reduce span lengths to 80–100m, and opt for UV-resistant coatings to withstand storm conditions.

For coastal environments, choose corrosion-resistant OPGW hardware made of hot-dip galvanized steel or aluminum alloy with salt-spray certifications (ISO 9227). Prioritize sealed splice closures (IP68 rated) and stainless steel suspension clamps to withstand salty air and humidity. Ensure compliance with IEC 61396 for longevity.
