Handling and Using GI Cable
Optical Fiber Cable is constructed to withstand the handling necessary during normal installation and usage,
but unlike copper wiring, special tools and skills are required to repair Optical Fiber Cable if it is accidentally
cut. Plan the installation carefully to avoid damaging the cables.
Transport and Storage
Optical Fiber Cable is wound on a standard drum. It can be transported just like copper wire cables, but it is
lighter than copper wire cable so be sure to use less force when handling the Optical Fiber Cable.
Optical Fiber Cable can be stored at temperatures between –40
°
C and 70
°
C. To prevent the infiltration of
humidity, seal both ends of the cable with cable caps or other means. Be especially careful to prevent the infil-
tration of moisture when connectors are attached to the ends of the cable.
Installation Precautions
There are limits on the maximum tension and minimum bending radius that the Optical Fiber Cable can with-
stand. Handle the cable carefully because the cable may break or have increased transmission loss if these
limits are exceeded.
Pulling Tension
The pulling tension on the cable can be measured with a pulley as shown in the following diagram.
The pulling tension (T) on the cable can be calculated from the tension reading (T
1
) at the pulley and the angle
(
θ
) at the pulley.
If the pulling tension exceeds the maximum tension, install a pull box midway through the run as shown in the
following diagram. Pull the required amount of cable to the pull box, lay it out in figure-8 loops, and then pull the
cable through the remaining section of the run.
