9.2.6 Pulling Backbone—Horizontal
Backbone cable is used to interconnect telecommunications rooms on the same floor.
Cable sheaves may be necessary to handle the cable from the reel location to the point where it
will be pulled. In the room where the cable will enter the horizontal pathway, a bullwheel may
be required to ensure that the jacket is not damaged as it enters the pathway.
9.2.7 Cable Pulling Precautions
To verify receipt of undamaged cable, while the cable is still on the reel, the installer should
verify that there is continuity with the cable still on the reel. For copper cable, continuity can be
verified by use of an ohm-meter.
For optical fiber cable, continuity can be verified by shining a light source into the fiber strands
or using a power meter or optical time domain reflectometer (OTDR), prior to installation.
Innerduct may be placed inside conduit, through sleeves, or placed in cable trays to facilitate
cable pulls, cable removal, and to relax pulling tension exerted on the cable.
