ADSS fiber optic cable and cable combined fastening bracket

ADSS fiber optic cable combined fastening brackets are specialized hardware used to securely attach and support ADSS cables on poles or towers, ensuring mechanical stability and protecting the fiber from stress.

Purpose of Combined Fastening Brackets

ADSS (All-Dielectric Self-Supporting) fiber optic cables require mechanical support along their aerial routes. Combined fastening brackets are designed to:

• Secure the cable to poles, towers, or walls
• Maintain proper tension and prevent sagging
• Protect the fiber from bending, vibration, and environmental stress
• Allow for easy installation and maintenance without specialized tools These brackets are often used in conjunction with suspension clamps, tension clamps, and anchor clamps to provide a complete support system for ADSS cables .

Types of Brackets and Accessories

1. Suspension Clamps:
   • Used for mid-span support of ADSS cables
   • Allow the cable to hang freely while controlling bending stress
   • Can be fixed to poles using bolts, bands, or J-hooks
   • Suitable for spans ranging from 100 to 600 meters depending on design
2. Tension Clamps (Dead-End Clamps):
   • Installed at terminal points or where the cable route changes direction
   • Provide a rigid hold to transfer mechanical loads to poles or towers
   • Often include preformed helical rods and corrosion-resistant fittings to protect fibers
3. Anchor Clamps:
   • Used to fasten cables vertically along poles or towers
   • Designed to prevent slipping, shaking, or vibration
   • Typically made with stainless steel bands and UV-stable elastomers for durability
4. Fiberglass Brackets (e.g., FIBERLIGN®):
   • Provide standoff distances and multiple end-fitting options
   • Useful when pole space is limited
   • Can expand existing installations economically using adapter fittings

Installation Considerations

• Brackets and clamps must be rated for the mechanical load of the cable and environmental conditions such as wind, ice, or seismic activity
• Proper alignment and tensioning are critical to avoid fiber stress or damage
• Combined fastening brackets often integrate multiple functions, allowing suspension, tensioning, and anchoring in a single unit for efficient deployment
• Accessories should comply with international and TEC specifications to ensure long-term reliability

Summary

Using ADSS fiber optic cable combined fastening brackets ensures that cables are mechanically stable, protected from environmental stress, and properly tensioned along aerial routes. Selecting the right combination of suspension clamps, tension clamps, anchor clamps, and fiberglass brackets is essential for safe, durable, and efficient fiber optic network installations .
