All dielectric aerial outdoor ފިރްs (ADSS cables) eliminate metal components, preventing lightning strikes and electromagnetic interference. Unlike arއެއުރެންނަށްޓަކައިd cables, they use reinforced glass yarn and hydrophobic gel for tension resistance and moisture protection. Telecom giants like Verizon saved 37% on tower maintenance after switching (CRU International 2024).
All Dielectric vs. Metallic Aerial Cables – Critical Comparison
Factor | All Dielectric Cable | Metallic Cable |
---|---|---|
Lightning Resistance | ✅ Immune | ❌ High-risk |
Weight | 0.6 kg/m (lighter) | 1.2 kg/m (heavier) |
Corrosion Risk | None | High in coastal areas |
Installation Cost | $0.8/m | $1.5/m |
Route Survey: Check pole load capacity & vegetation clearance (FCC Rule 47 CFR §1.1402).
Hardware Prep: Install vibration dampers every 20m – skipping this caused a 2023 Minnesota fiber outage.
Tension Control: Use dynamometer; max 20% of cable tensile strength (typically 6,000N).
Sag Adjustment: Allow 1-2% sag at 60°F to prevent ice damage.
Ground Clearance: Maintain 5.5m above roads (OSHA 1926.964).
⚠️ Warning: Never install near high-voltage lines (<3m) – dielectric breakdown occurs at 20kV/cm!
✅ Quarterly visual inspection for sheath damage
✅ Annual tension testing
✅ Clean suspension hardware with non-corrosive solvent
❌ Never use metal clamps (causes micro-bending)
FAQs: All Dielectric Aerial Outdoor Fiber Optic Cable
Q1: Can it withstand hurricane-force winds?
A: Yes – tested to 150mph when installed with extra-long span clamps (IEC 61300-2-22 certified).
Q2: Maximum span length between poles?
A: 100-150m (varies by cable diameter/tension). Beyond 150m, use intermediate support braces.
Q3: Does temperature affect performance?
A: Operating range is -40°C to 85°C. Signal loss increases by 0.003dB/km per °C below freezing – negligible for most runs.
Q4: How long does the jacket last outdoors?
A: UV-resistant HDPE lasts 25 years. Coastal areas: Choose marine-grade jackets to resist salt corrosion.

Q5: Can birds damage these cables?
A: Rare – but use spiral vibration dampers if birds frequently perch. Prevents "galloping" that causes fatigue.
