Remove the fiber optic cable and then hang it on the pole

To safely remove and hang a fiber optic cable on a pole, proper planning, equipment, and adherence to aerial installation standards are essential.

Preparation and Safety

Before starting, survey the route and existing pole conditions to identify obstacles, clearance issues, and structural integrity of poles . Ensure all necessary permits and approvals are obtained if working on shared utility poles . Use personal protective equipment (PPE), including gloves, safety harnesses, and helmets, and follow all safety protocols for working at heights .

Removing the Existing Cable

1. Inspect the cable and support strands for damage or tension issues .
2. Detach the cable from hooks, clamps, or lashing while ensuring the cable is supported to prevent sudden drops or bending beyond its minimum bend radius .
3. Remove any old support strands or temporary guy wires if necessary, taking care not to disturb other utilities on the pole .

Hanging the Cable on the Pole

1. Install or verify support strands (messenger wires) to carry the cable load. These should be taut and anchored properly to withstand environmental stress .
2. Attach the fiber optic cable to the support strand using hooks, clamps, or lashing methods depending on the cable type (self-supporting or hanging wire type) .
3. Maintain proper sag and tension: sag should generally be less than 2% of the span length, and tension should not exceed 30% of the cable's minimum breaking strength .
4. Ensure clearance from electrical lines and other cables: maintain safe separation distances to prevent interference or hazards .
5. Secure service loops and splice closures at poles, respecting the cable's minimum bend radius (typically 10 times the cable diameter for long-term bends) .

Final Checks

• Verify that the cable is evenly supported along the span and that no loose sections are hanging .
• Confirm that anchors, guy wires, and clamps are properly installed to prevent sagging or movement during wind or adverse weather .
• Document the installation and report any damage to existing cables or infrastructure . Following these steps ensures that the fiber optic cable is safely removed, properly supported, and securely hung on the pole, maintaining both performance and safety standards.
