Our Professional Answer: For efficient and safe underground data cable installation, a suite of specialized tools is necessary. This includes:

• Cable pullers or winches: These are essential for pulling heavier or longer cables through underground conduits. They provide a consistent, controlled pulling force and often come with built-in dynamometers to monitor tension.

• Cable pulling grips (also known as "towing socks"): These devices securely attach to the end of the cable, distributing the pulling force evenly and preventing damage.

• Duct rodders and fish tape: These are used to pre-install a pull line or "mule tape" through the conduit before the actual cable pull. For fiber optic cables, non-conductive fiberglass rods are preferred for their flexibility and safety.

• Cable lubricants: Applying a low-friction, residue-free lubricant is crucial to reduce pulling tension and prevent the cable jacket from being damaged by friction.
