Fiber optic cable is pulled by first preparing the cable end to properly attach a pulling grip, then using the grip to guide the cable through the conduit or pathway.
Here's a breakdown of the process:
-
Cable Preparation: This crucial first step involves careful preparation of the cable end to securely attach the pulling grip.
-
Expose Strength Members: Slide the grip past the end of the cable. Cut back the cable jacket to expose the strength members. These are essential for bearing the pulling force.
-
Protect the Core: Use friction tape to cover approximately three inches of the cable core and jacket. This prevents damage and provides a secure base for the grip.
-
-
Pulling Grip Attachment: This is where the pulling grip is attached to the prepared cable end.
-
Position the Grip: Position the pulling grip over the cable core and the tape that's been applied.
-
Secure the Grip: Tape the grip securely in place. This ensures a strong connection between the cable and the pulling mechanism.
-
-
Pulling Process: Once the grip is securely attached, the cable can be pulled through the conduit or pathway.
- Use Appropriate Equipment: Use equipment appropriate for the weight and length of the cable pull. This might include a winch, pulling tape, or fish tape.
- Maintain Tension: Maintain consistent tension on the cable to avoid snags and damage.
- Lubricate if Necessary: Use cable lubricant to reduce friction, especially when pulling through long or complex pathways.
- Avoid Sharp Bends: Pay close attention to the cable's bend radius to avoid kinking or damaging the fibers.
In essence, the process focuses on protecting the delicate fiber core while transferring the pulling force to the cable's strength members. Proper preparation and technique are crucial for a successful and damage-free cable pull.
