II – III 2025/2026 Exam Questions and
Answers | 100% Solved
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.
