Buried installation of BrightPath ® distribution cable
BrightPath cable can be either directly buried or buried as fiber optic cable in conduit (FOCIC). It can be plowed
into position using a vibratory plow or buried in a trench. Buried BrightPath cable should be installed at least 18 in.
(45 cm) deep, and deeper if the frost line is farther down.
For vibratory plowing instructions, see pages 5.2 to 5.3.
For trenching instructions, see pages 5.4 to 5.8.
Upstream/headend orientation
Whatever method you choose, keep in mind which end of the cable/FOCIC is the
upstream end. The BrightPath taps will not work properly if they are installed back-
ward. Always know which end is upstream (the side pointed toward the headend)
and mark it per instructions.
Handling FOCIC
FOCIC reels are substantially larger than traditional cable reels. Work with your CommScope customer representa-
tive to make sure your carrier can accommodate FOCIC reels.
Cut the cable restraint before installation
Prior to installation, remove the FOCIC end cap and cut the cable restraint. This relaxes the cable and transfers all
of the pulling tension to the conduit. Replace the cap immediately.
Keep the FOCIC capped
Make sure both ends are capped during installation to maintain conduit integrity.
Leave more than enough cable for splicing to the headend cable or node
IN ALL CABLE INSTALLATION SCENARIOS, MAkE SURE THAT yOU LEAVE SUFFICIENT CABLE FOR ATTACH-
MENT TO THE HEADEND CABLE OR THE NODE. The node may not yet be in place when the cable is being
installed. Confirm the planned location of the node before installation.
