Maintenance Tech II-III Conventional
EXAM WITH ANSWERS
In what application is a splice closure used? - CORRECT
ANSWERS ✔✔Splice closures are used to protect optical
fibers and splices against a full range of environmental
changes in aerial installations or blow ground in vaults.
When preparing a fiber-optic cable for splicing, what is
the purpose of removing approximately 1 inch of jacket
and any armor that is present, from the end of the cable?
- CORRECT ANSWERS ✔✔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 ANSWERS ✔✔Water causes the glass 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
ANSWERS ✔✔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 ANSWERS ✔✔Splice trays are designed to
provide protection for mechanical splices, fusion splice
protectors, as well as provide storage for the required
fiber slack.
How should buffer tubes be secured in the closure? -
CORRECT ANSWERS ✔✔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 ANSWERS ✔✔Retaining clips hold optical
splices in place in a splice tray.
What is the purpose of buffer tubes in fiber-optic cable? -
CORRECT ANSWERS ✔✔Buffer tubes protect and separate
the optical fibers 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 ANSWERS ✔✔To prevent the
accidental transfer of fiber debris or fiber chips onto clean
hands.
