Maintenance tech II-III conventional Exam with correct || || || || || || ||
detailed 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
|| || ||
What are some prerequisites before preforming a fusion splice of optical fiber?
|| || || || || || || || || || ||
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
|| || || || || || || || || || || || ||
When would a mid-entry splice in a fiber-optic network be used?
|| || || || || || || || || ||
In a self-healing ting network that requires only teo fibers to feed an optical fiber drip.
|| || || || || || || || || || || || || || ||
What is required for a mechanical splice used for acceptance testing?
|| || || || || || || || || ||
A mechanical splice used for acceptance testinf shpuld be simple to ise and reusable
|| || || || || || || || || || || || ||
Why are Velcro straps preferred over standards plastic tie wraps when bundling pigtails for
|| || || || || || || || || || || || || ||
storage in a splice panel? || || || ||
Becase velcro strapa are removable and can hold the pigtail together without placing undue
|| || || || || || || || || || || || || ||
strain on the optical fibers.
|| || || ||
When preparing fiber-optic cable for connection to a patch panel, how much buffer tub and
|| || || || || || || || || || || || || || ||
fiber slack should be provided?
|| || || ||
Leave enough slack in the buffer tubes to allow the solice trays to reach the splicing
|| || || || || || || || || || || || || || || ||
equipment and enough fiber slack to store on individual tray for later additions, move and
|| || || || || || || || || || || || || || ||
changes
If tight-buffered distribution fiber-optic cable is installed between the master splice panel in
|| || || || || || || || || || || || ||
an optical entrance enclosure (OEE) and a rack mounted fiber-optic distribution panel,
|| || || || || || || || || || || ||
where in the facility must the distribution panel be located?
|| || || || || || || || ||
The distribution panel can be located anywhere in the facility since the distribution cable
|| || || || || || || || || || || || || ||
complies with the indoor code requirements for riser or plenum installation
|| || || || || || || || || ||
