1.In what applications is a splice closure used? -CORRECT ANSWER Splice
Closures are used to protect optical fibers and splices against a full range of
environmental changes in aerial installations or below ground in vaults.
2.When preparing a fiber-optic cable for splicing, what is the purpose of removing
approximately 2.5 cm (1 inch) of jacket and any armor that is present, from the end of
the cable?When preparing a fiber-optic cable for splicing, what is the purpose of
removing approximately 2.5 cm (1 inch) of jacket and any armor that is present, from
the end of the cable? -CORRECT ANSWER To access the cables rip cord and to
check the cutting depth of the knife or ringing tool.
3.What does water do to the glass core of an optical fiber? -CORRECT ANSWER
Water causes the glass core of the optical fiber to become opaque, which degrades the
signal as its transported through the fiber.
4.When preparing a splice closure, what should be done with the fiberglass rod strength
member that runs down the center of loose-tube fiber optic cable? -CORRECT
ANSWER Trim the strength member back for convenience, but leave it long enough to
be tightly clamped to a strain-relief lug in the closure.
5.What is the purpose of splice trays inside splice closures? -CORRECT ANSWER
Splice trays are designed to provide protection for mechanical splices, fusion splice
protectors, and optical splitters as well as provide storage for the required fiber slack.
6.How should the buffer tubes be secured in the closure? -CORRECT ANSWER The
buffer tubes should be secured with tie wraps to allow slight movement without pulling
or stressing the optical fibers.
7.How are optical splices secured in a splice tray? -CORRECT ANSWER Retaining
clips hold optical splices in place in a splice tray.
8.What is the Purpose of Buffer tubes in a fiber optic cable? -CORRECT ANSWER
Buffer tubes protect and separate the optical fiber in smaller bundles
,9.When splicing fiber-optic cable, why is it a good safety practice to clean off fiber
strippers and other hand tools after each use? -CORRECT ANSWER To prevent the
accidental transfer of fiber debris or fiber chips onto clean hands.
10.Where would you expect to install a mid-entry splice in a fiber-optic cable network? -
CORRECT ANSWER A location where a select number of optical fibers need to be
spliced, and the remaining buffer tubes and fibers remain untouched.
11.Which type of fusion splicer is ideal for fiber-to-the-x (FTTx) splicing? -CORRECT
ANSWER The fixed V-Groove splicer.
12.When would a mid-entry splice in a fiber-optic network be used? -CORRECT
ANSWER In a self-healing ring network that requires only two fibers to feed an optical
fiber drop.
13.What is required of mechanical splices used for acceptance testing? -CORRECT
ANSWER A mechanical splice used for acceptance testing should be simple to use
and reusable.
14.What are some prerequisites before performing a fusion splice of optical fibers? -
CORRECT ANSWER A controlled environment such as a splicing van, trailer or tent
and a stable work surface that is large enough to accommodate the fusion splicer, tools,
and the splice closure.
15.Why are Velcro straps preferred over standard plastic tie wraps when bundling
pigtails for storage in a splice panel? -CORRECT ANSWER Because Velcro straps
are removable and can hold the pigtails together without placing undue strain on the
optical fibers
16.When preparing fiber-optic cable for connection to a patch panel, how much buffer
tube and fiber slack should be provided? -CORRECT ANSWER 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
17.If tight-buffered distribution fiber optic cable is installed between the master splice
panel in an optical entrance enclosure (0EE) and a rack-mounted fiber-optic distribution
panel, where in the facility must the distribution panel be located? -CORRECT
ANSWER The distribution panel can be located anywhere in the facility since the
distribution cable complies with indoor code requirements for riser or plenum
installations.
, 18.The quality and attenuation value of a mechanical splice of optical fibers is
dependent on which tool during the preparation process? -CORRECT ANSWER The
quality and attenuation value of the mechanical splice of optical fibers is dependent on
the quality of the cleaving tool.
19.What step should be performed at the beginning of every fusion splicing operation? -
CORRECT ANSWER Make a number of test splices to set up the fusion splicer and
to verify the instrument's settings and calibration for both the environment and the type
of fiber to be spliced.
20.Which fusion splicer alignment method uses a camera to align the optical fibers
before splicing? -CORRECT ANSWER The profile alignment system (PAS) method.
21.The National Electrical Safety Code (NESC) provides guidelines concerning which
portion of the fiber-optic cable network? -CORRECT ANSWER Minimum safety
clearances between different conductors of overhead and underground electric supply
and communications lines.
22.What is a safety concern when aerial fiber-optic cable is installed between poles,
even though there are no high-voltage power lines? -CORRECT ANSWER The
buildup of lethal amounts of static electricity on the fiber-optic cable that can discharge
through a person on a ladder or some other conductor connected to ground.
23.What is used in outside plant fiber-optic cable to protect and isolate the optical fibers
from stress? -CORRECT ANSWER Strength members and buffer tubes.
24.What is the purpose of grounding to earth? -CORRECT ANSWER To protect
against the adverse effects of lightning and assist in the reduction of static.
25.What is the minimum amount of slack that must be provided for splicing fiber-optic
cable in underground installations? -CORRECT ANSWER 15 meters on both the
inbound and outbound span.
26.What information is documented at fiber-optic slack and splice locations? -
CORRECT ANSWER Incoming and outgoing sequential markings showing the
cable's physical length.
27.What can be attached to the pulling line to prevent the fiber-optic cable from twisting
during installation? -CORRECT ANSWER A break-away swivel.
28.What are two critical factors for a successful installation of fiber-optic cable? -
CORRECT ANSWER Cable pulling tension and cable bend radius.
