The "Figure-8" technique is a well-known best practice for managing long lengths of cable during installation, especially for fiber optics. When pulling a cable over a long distance, a single pull may be impossible due to friction and increasing tension. The process involves:

1. Pulling the first section of cable into the conduit.

2. Laying the remaining cable on the ground in a large, elongated figure-8 pattern.

3. Turning the figure-8 over to remove any twists.

4. Reversing the pull and pulling the cable from the figure-8 into the next section of the conduit.

This method allows for a smooth, tension-free pull and prevents the cable from twisting, which is a major cause of signal degradation in fiber optic networks.
