◉ 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 cable's 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 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 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 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.
◉ What are some prerequisites before performing a fusion splice of
optical fibers? Answer: A controlled environment such as a splicing van,
