Maintenance tech II-III conventional
EXAM WITH ANSWERS
In what application is a splice closure used?
Splice clousures 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 2.5cm (1inch) of
jacket and any armor that is present, from the end of the
cable?
To acceas the cable rip cord and to chexk the cutting
depth of the knife or ringing tool
What does water do to the glass core of an optical fiber?
Water causes the glass forebod the optical fiber to
become opaque, which degreades 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 the loose-tube fiber-optic cable?
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 tray inside a splice
closures?
Splice trays are designed to provide protection for
mechanical splices, fusion splice protectors, and optical
spliters as well as provide storage foe the required fiber
slack
How should the buffer tubes be secured in the closure?
The buffer tubes should be secured with tie wraps to
allow slight movement without pulling or stressing the
optical fibers
How are the optical splices secured in a splice tray?
Retaining clip hold optical splices in place in a aplice tray
, What is the purpose of a buffer tubes in fiber-optic
cables?
Buffer tubs protect and separate the optical fiber in sallee
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?
To prevent the accidental transfer of diber debris or fiber
chips onto clean hands
Where would you expect to install a mid-entry splice in a
fiber-optic cable next work?
A location where a select number of optixal fibers bees to
be spliced, and the remaing buffer tubes and fibers
remian untouched.
Which type of fusion splicer is ideal for fiber-to-the-
x(FTTx) splicing?
The fixed V-groove splicer
