Questions With Comprehensive Solutions
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.
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.
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.
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.
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.
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.
How are optical splices secured in a splice tray? Correct Answer -
Retaining clips hold optical splices in place in a splice tray.
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
, 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.
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.
Which type of fusion splicer is ideal for fiber-to-the-x (FTTx) splicing?
Correct Answer - The fixed V-Groove splicer.
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.
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.
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.
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
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
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-
