Introducing Fiber-Optic Networks Exam
Questions And Answers Verified 100% Correct
How are optical splitters used in the forward path? - ANSWER In the forward path,
optical splitters are used as passive branching devices that divide an optical signal
across multiple output fibers.
Which optical splitter package is similar in appearance and size to a standard fusion
splice protector? - ANSWER Fused biconical taper (FBT).
In what applications is a splice closure used? - ANSWER Splice closures are used to
house electronics and spare cable, along with optical patch or splice panels.????
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? - 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.
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? - 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 Cable 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 fiber debris or 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 a 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 (FTTx) 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.
If tight-buffered distribution fiber-optic cable is installed between the master splice panel
in an optical entrance enclosure (OEE) and a rack-mounted fiber-optic distribution
panel, where in the facility must the distribution panel be located? - 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.
The quality and attenuation value of a mechanical splice of optical fibers is dependent
on which tool during the preparation process? - ANSWER The quality and attenuation
value of the mechanical splice of optical fibers is dependent on the quality of the tool
used to strip the protective coating from the fiber.????
What step should be performed at the beginning of every fusion splicing operation? -
ANSWER Make a number of test splices to set up the fusion splicer and to verify the
