INSTALLING FIBER-OPTIC CABLE IN
OUTSIDE PLANT Correct 100%
What is the minimum clearance in the middle of a cable span between the power's secondary conductor
and the fiber-optic cable belonging to a broadband cable operator? - ANSWER 30 inches.
When installing aerial fiber-optic cable employing the back-pull method, how should the cable trailer be
positioned in order to keep the cable from rubbing on the pole or cable reel when pulled? - ANSWER The
trailer should be positioned in line with the strand and at least twice the distance from the pole as the
height from the ground to the set-up chute.
In underground installations, what are two recommended techniques that prevent the pulling tension
through the conduit from exceeding the pulling tension specification of the fiber-optic cable? - ANSWER
The midpoint pull and the intermediate pull.
How is the high air speed blowing (HASB) method of installing fiber-optic cable in conduit different from
other methods? - ANSWER There is no need for a pulling rope in the conduit before the cable is installed.
Eliminating pulling lines using high air speed blowing (HASB) can achieve how much of a cost savings
over conventional pulling techniques? - ANSWER More than 40%.
When is it necessary to use the intermediate pull technique to install fiber-optic cable in conduit? -
ANSWER When the cable route has multiple 90° bends throughout.
When installing fiber-optic cable over coaxial cable, what should be done at the coaxial cable expansion
loops? - ANSWER Secure the fiber-optic cable to the strand across the coaxial cable expansion loops
using plastic cable ties or support straps.
What are some advantages of using flexible conduit? - ANSWER Low coefficient of friction (COF) and the
capability to bend around corners and obstructions with minimal splices.
What can be used as a pulling line in a conduit that is missing a pull line? - ANSWER An unused cable that
is already installed in the conduit.
