Adding fiber optic cable via suspension wire

Fiber optic cables are typically suspended on a steel messenger wire using clamps, bands, or specialized suspension kits to ensure proper tension, sag, and protection from mechanical stress.

Choosing the Suspension Wire

For aerial fiber optic installations, use a galvanized steel strand as the suspension wire. Common specifications are 7/2.2 mm for standard cables, or 7/2.0 mm for armored cables. The wire must support the cable's weight and withstand environmental forces like wind and vibration (Bonelinks) .

Tools and Accessories

You will need:

  • Suspension clamps (e.g., HC-8-15) suitable for the cable diameter
  • Stainless steel bands and buckles
  • Strapping or banding tool (e.g., MBT-004)
  • Hammer for securing hardware
  • Optional catenary suspension kits for tool-free tensioning and rapid installation (Gripple)

Installation Steps

  1. Prepare the Suspension Wire: Stretch the steel strand between poles according to design specifications, ensuring proper sag and tension. The sag should account for cable elongation under load (Bonelinks) .
  2. Attach the Clamp: Insert the stainless steel band through the clamp and buckle, then tighten using the strapping tool. Remove the polymer gasket if present, place the fiber optic cable inside, and secure the clamp by tightening the screw (YouTube Jera Line) .
  3. Position the Cable: Place the cable gently on the suspension wire, ensuring it is evenly supported. Maintain a minimum bend radius of 20 times the cable diameter under tension and 10 times after installation to prevent damage (Bonelinks) .
  4. Spacing and Hooks: Install clamps or hooks at regular intervals, typically 50 cm apart, with a tolerance of ±3 cm. Adjust hook sizes to match the cable diameter (Bonelinks) .
  5. Tensioning: For long spans, use tensioning devices or catenary kits to maintain proper cable elevation and reduce stress from wind or vibration (Gripple) .

Installation Methods

  • Moving Reel Method: The cable is deployed from a reel while being lashed to the suspension wire in one continuous operation.
  • Stationary Reel Method: Used for inaccessible routes; the cable is pulled into place and temporarily supported by cable blocks before securing (Corning FlexNAP) .

Safety and Handling

  • Avoid excessive pulling tension, sharp bends, or crushing forces.
  • Use proper personal protective equipment when working at height.
  • Ensure clamps and bands do not damage the cable jacket. By following these steps and using the correct hardware, fiber optic cables can be safely and efficiently suspended on a messenger wire, ensuring long-term performance and protection from environmental stress.
