Update.
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.
