Fiber Install and Activation Exam Study Guide
Questions And Answers Verified 100% Correct
In an optical network, what is reflectance? - ANSWER Reflectance is the reflected
light from a single Fresnel refection event
How should surface particulates usually be removed from optical connectors? -
ANSWER By using a compressed-air cleaner designed for optical connectors.
Since they provide the same functions, what is the primary difference between the fiber
distribution hub (FDH)and fiber access terminal? (FAT) - ANSWER The FAT is
typically easier to install and has a lower fiber counts than the FDH.
Which statement about pigtails used for optical fiber terminations is true? - ANSWER
Prior to splicing, pigtails should be labeled to correspond with the correct color code and
patch panel designation.
How are optical splitters used in the forward path? - ANSWER In the forward path,
optical splitters are used as passive combining devices that stream an optical signal
across two common fibers.
Which optical splitter package is similar in appearance and size to a standard fusion
splice protector? - ANSWER Fused bi-conical taper (FBT)
In what applications is a splice closure used? - 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.
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?
- ANSWER To access the cable's rip cord and to check the cutting depth of the knife
or ringing tool.
What does water do to the glass core of an optical fiber? - ANSWER Water causes
the glass core of the optical fiber to become opaque, which degrades the signal as it's
transported through the fiber.
Whe 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? - 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.
, What is the purpose of splice trays inside splice closures? - 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.
How should the buffer tubes be secured in the closure? - ANSWER The buffer tubes
should be secured with tie wraps to allow slight movement without pulling or stressing
the optical fibers.
How are optical splices secured in a splice tray? - ANSWER Retaining clips hold
optical splices in place in a splice tray.
What is the purpose of buffer tubes in fiber-optic cable? - ANSWER Buffer tubes
protect and separate the optical fiber in smaller bundles.
When splicing fiber-optic cable, why is it a good safety practice to clean off fiber
strippers and other hand tools after each use? - ANSWER To prevent the accidental
transfer of the fiber debris to fiber chips onto clean hands.
Where would you expect to install a mid-entry splice in a fiber-optic cable network? -
ANSWER A location where select number of optical fibers need to be spliced, and the
remaining buffer tubes and fibers remain untouched.
Which type of fusion splicer is ideal for fiber-to-the-x splicing? - ANSWER The fixed
V-groove splicer.
What are some prerequisites before performing a fusion splice of optical fibers? -
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.
When would a mid-entry splice in a fiber-optic network be used? - ANSWER In a
self-healing ring network that requires only two fibers to feed an optical fiber drop.
What is required of mechanical splices used for acceptance testing? - ANSWER A
mechanical splice used for acceptance testing should be simple to use and reusable.
Why are Velcro straps preferred over standard plastic tie wraps when bundling pigtails
for storage in a splice panel? - ANSWER Because Velcro straps are removable and
can hold the pigtails together without placing undue strain on the optical fibers.
When preparing fiber-optic cable for connection to a patch panel, how much buffer tube
and fiber slack should be provided? - 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.
