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 (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? - ANSWER: To access the cables 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 its
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: Retaining clips hold
optical splices in place in a splice tray.
What is the Purpose of Buffer tubes in a 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.
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.
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.
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 (0EE) 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 cleaving tool.
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
instrument's settings and calibration for both the environment and the type of fiber
to be spliced.
Which fusion splicer alignment method uses a camera to align the optical fibers
before splicing? - ANSWER: The profile alignment system (PAS) method.
