When laying loops of fiber on a surface during a pull, use “figure-8” loops to prevent twisting the cable. The figure 8 puts a half twist in on one side of the 8 and takes it out on the other, preventing twists. Pull the cable out of the conduit or. Minimize mechanical pressure on the outer sheath at crossing points: (armoured) cables crossing each other generate points of high pressure, so it is important when laying in figure 8 loops it is done in a correct way. The cable is placed on the ground in a figure 8 pattern. Commonly referred to as figure 8 cable, figure 8. Corning Optical Communications self-supporting (figure-8) optical fiber cable greatly simplifies the task of placing fiber optic cable on an aerial plant.
