ACTUAL QUESTIONS AND CORRECT ANSWERS
Question:
1. In what application is a splice closure used?
Answer:
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
Question:
2. 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?
Answer:
To acceas the cable rip cord and to chexk the cutting depth of the knife or ringing tool
Question:
3. What does water do to the glass core of an optical fiber?
Answer:
Water causes the glass forebod the optical fiber to become opaque, which degreades the signal as it's
transported through the fiber.
Question:
4. 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?
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
Question:
5. What is the purpose of splice tray inside a splice closures?
Answer:
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
Question:
6. 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
Question:
7. How are the optical splices secured in a splice tray?
Answer:
Retaining clip hold optical splices in place in a aplice tray
, Question:
8. What is the purpose of a buffer tubes in fiber-optic cables?
Answer:
Buffer tubs protect and separate the optical fiber in sallee bundles
Question:
9. 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 diber debris or fiber chips onto clean hands
Question:
10. Where would you expect to install a mid-entry splice in a fiber-optic cable next work?
Answer:
A location where a select number of optixal fibers bees to be spliced, and the remaing buffer tubes and
fibers remian untouched.
Question:
11. Which type of fusion splicer is ideal for fiber-to-the-x(FTTx) splicing?
Answer:
The fixed V-groove splicer
Question:
12. What are some prerequisites before preforming a fusion splice of optical fiber?
Answer:
A controlled environment such as a solicing van, teailer, or tent and a stable work surface that is large
enough to accommodate the fusion splicer, tools, and the splice clouser
Question:
13. When would a mid-entry splice in a fiber-optic network be used?
Answer:
In a self-healing ting network that requires only teo fibers to feed an optical fiber drip.
Question:
14. What is required for a mechanical splice used for acceptance testing?
Answer:
A mechanical splice used for acceptance testinf shpuld be simple to ise and reusable
Question:
15. Why are Velcro straps preferred over standards plastic tie wraps when bundling pigtails for storage in a
splice panel?
Answer:
Becase velcro strapa are removable and can hold the pigtail together without placing undue strain on the
optical fibers.
