103 Multiple choice questions
Term 1 of 103
What is an example of transport media in a telecommunications network?
Coaxial cable.
Twinax cable.
Fiber optic cable.
Twisted pair cable.
Term 2 of 103
What are two critical factors for a successful installation of fiber-optic cable?
Strength members and buffer tubes.
Software packages, which electronically automate system records.
Cable pulling tension and cable bend radius.
A lead technician would likely document troubleshooting results.
Term 3 of 103
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?
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.
The basic resources required to respond to a major system outage are documentation,
technical skill, and basic troubleshooting/repair equipment and materials.
The distribution panel can be located anywhere in the facility since the distribution cable
complies with indoor code requirements for riser or plenum installations.
Secure the fiber-optic cable to the strand across the coaxial cable expansion loops using
plastic cable ties or support straps.
,Term 4 of 103
Eliminating pulling lines using high air speed blowing (HASB) can achieve how much of a cost
savings over conventional pulling techniques?
Less than 40%.
More than 15%.
More than 40%.
More than 65%.
Term 5 of 103
What is an option available on most optical nodes for connecting to the power supply?
The offline type routes incoming power directly to connected devices and switches to
battery backup during a power interruption.
Through a power cable that is connected from the power supply directly to the power
port of the node.
A P2MP topology consists of a host element connected through a splitter or optical
coupler to two or more receiving elements.
An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the
customer premises.
Term 6 of 103
Which fusion splicer alignment method uses a camera to align the optical fibers before
splicing?
The fixed v-groove method.
The profile alignment system (PAS) method.
The fixed v-groove splicer.
The estimate of system loss (esl) method.
,Term 7 of 103
When preparing a fiber-optic cable for splicing, what is the purpose of removing
approximately 2.5 cm of jacket and any armor that is present, for the end of the cable?
Trim the strength member back for convenience, but leave it long enough to be tightly
clamped to a strain-relief lug in the closure.
To access the cable's rip cord and to check the cutting depth of the knife or ringing tool.
Leave enough slack in the buffer tubes to allow the splice trays to reach the splicing
equipment and enough fiber slack to store on individual trays for later additions, moves,
and changes.
Changing the infrastructure all at once would cause too many service disruptions.
Term 8 of 103
What should be done to prevent the buildup of lethal amounts of static electricity on long
lengths of aerial fiber-optic cable?
An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the
customer premises.
Changing the infrastructure all at once would cause too many service disruptions.
Static electricity that can discharge through a person on a ladder or some other
conductor connected to ground.
Install grounding clamps, which connect the cable exterior and metallic messengers to a
good solid ground at each pole site.
Term 9 of 103
What is a safety concern when aerial fiber-optic cable is installed between poles, even though
there are no high-voltage power lines?
Secure the fiber-optic cable to the strand across the coaxial cable expansion loops using
plastic cable ties or support straps.
To prevent the accidental transfer of fiber debris or fiber chips onto clean hands.
The offline type routes incoming power directly to connected devices and switches to
battery backup during a power interruption.
Static electricity that can discharge through a person on a ladder or some other
conductor connected to ground.
, Term 10 of 103
What is the minimum amount of slack that must be provided for splicing fiber-optic cable in
underground installations?
Cable pulling tension and cable bend radius.
30 inches.
Strength members and buffer tubes.
15 meters on both the inbound and outbound span.
Term 11 of 103
What is one reason why broadband cable operators install fiber-optic cable in stages instead
of changing the infrastructure all at once?
To prevent the accidental transfer of fiber debris or fiber chips onto clean hands.
Static electricity that can discharge through a person on a ladder or some other
conductor connected to ground.
Changing the infrastructure all at once would cause too many service disruptions.
Use the existing coaxial network infrastructure.
Term 12 of 103
When is it necessary to use the intermediate pull technique to install fiber-optic cable in
conduit?
This reverse polarity is a means of mitigating electrolytic corrosion on the outside plant.
15 meters on both the inbound and outbound span.
The back-pull method and the drive-off method.
When the cable route has multiple 90° bends throughout.
