Steel strapping for optical fiber cables is threaded through a tensioning tool, wrapped around the cable or bracket, and tightened to secure the cable without damaging it.

Selecting the Right Strap and Tool

Use stainless steel strapping suitable for fiber optic installations, typically up to 25mm wide and 1.15mm thick for heavy-duty applications . Choose a ratchet or hand-guided tensioning tool designed for optical fiber cable straps, which allows precise tensioning and cutting of excess strap .

Threading and Securing the Strap

1. Position the Cable or Bracket: Place the fiber optic cable on the mounting surface (pole, tower, or wall) and align the bracket if used.
2. Wrap the Strap: Pass the steel strap around the cable or bracket, ensuring it does not pinch or compress the cable jacket. Avoid overlapping the strap edges in a way that could create stress points .
3. Insert into the Tool: Feed the strap through the tensioning tool's slot according to the manufacturer's instructions. The strap should pass under the tool's tensioning wheel and through the locking mechanism.
4. Tension the Strap: Operate the ratchet or hand-guided tool to tighten the strap. Apply enough tension to secure the cable firmly but do not over-tighten, as excessive force can damage the cable jacket or cause “zippering” of armored tape .
5. Cut Excess Strap: Once the strap is properly tensioned, use the tool's cutting function to trim the excess strap, leaving a clean and safe installation .

Installation Precautions

• Avoid Cable Damage: Do not exceed the cable's maximum bend radius or pulling tension during installation .
• Protect Cable Ends: Cap or tape bare cable ends to prevent moisture ingress, especially for steel-armored cables .
• Check Strap Placement: Ensure straps are evenly spaced and do not create sharp pressure points on the cable jacket .
• Environmental Considerations: Stainless steel straps resist corrosion and are suitable for outdoor installations, providing long-term stability . By following these steps and using the correct tools, you can safely thread and secure steel strapping for optical fiber cables while maintaining cable integrity and long-term reliability.
