Vibratory plowing cable/FOCIC
CommScope strongly recommends a professionally-engineered single or double feed tube plow blade with a tube
at least 1/2 in. (13 mm) larger than the largest cable size and a radius of 12 in. (30 cm) or larger. At minimum, an
operator and a helper/feeder are needed for a plowing installation. Because terrain and soil types vary, contact your
plow manufacturer for their equipment recommendation.
Dig a trench deep enough and at least twice the length of the plow blade/chute for the plow blade to enter it
comfortably. A similar trench should be dug at the other end of the installation and at every pedestal location. The
cable/FOCIC may pay-off from the front of the tractor or from a stationary cable reel.
In the tractor method, make sure the reel is not run into objects that may damage the cable. Pay the cable over the
top of the reel. Do not use reel brakes.
In the stationary reel method, pull the cable end from the reel to the starting trench. Use cones to mark and protect
the cable/FOCIC from pedestrian and vehicle traffic.
Cap the FOCIC or tape the cable end to protect it. Remove the back plate from the blade and inspect the feed tube
for burrs, rough surfaces and sharp edges. Clean out any dirt or rocks. Carefully place the cable in the feeder tube.
Reattach the back plate. Pull enough FOCIC to connect to the splice point.
