How to install fiber optic cable pullers

To connect a fiber optic cable puller, attach the electronic control cords, connect the power supply, and secure the cable using the strength members with a pulling grip, following all safety and tension guidelines. Step 1: Prepare the Puller and Work AreaEnsure the puller is on a stable surface and clear of obstacles. Read all safety instructions in the puller manual, including warnings about hydraulic pressure and electrical hazards.

Verify that the relief valve is set to the recommended tension limit for your cable and capstan size. Step 2: Connect the Puller ElectronicsAttach the electronic cord from the control box to the puller. Connect the foot control valve assembly to the control box.

Plug the power cord from the vehicle or power source into the control box. Ensure all connections are secure and the control box is functioning before starting the pull. Step 3: Prepare the Fiber Optic CableExpose the strength members (Kevlar or aramid yarn) by carefully stripping a small portion of the outer jacket; do not pull on the glass fibers or outer jacket.

Attach a pulling eye or wire mesh grip to the strength members, looping and securing them with tape or knots to prevent slippage. Ensure the grip is tight and the mesh imprint is visible through the tape for proper compression. Step 4: Connect the Cable to the PullerAttach the pulling grip to the puller's capstan or pulling line.

If using a hydraulic puller, ensure the cable is aligned straight to avoid twisting. Check that the cable path respects the minimum bend radius to prevent fiber breakage. Lubricate the cable if required, using a lubricant compatible with the cable jacket.

For long runs, consider pulling from the middle out to both ends. Step 5: Test and MonitorPower on the puller and verify that the tension monitoring system is active. Set the maximum tension limit to prevent overloading the cable.

Begin pulling slowly, observing the cable for any signs of stress or twisting. Use the foot control to regulate speed and tension. Continuously monitor the tension readings and adjust as necessary to maintain safe pulling conditions.

Safety Tips

Never stand directly behind the puller or hoist people or equipment with it. Avoid twisting the cable; use a "figure 8" layout on the ground to prevent twists. Always measure the optical power or attenuation before and after pulling to ensure cable integrity.

Following these steps ensures a safe and effective connection of a fiber optic cable puller while protecting the cable from damage and maintaining proper tension throughout the installation.
