In what applications is a splice closure used?
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?
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?
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?
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?
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?
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?
Retaining clips hold optical splices in place in a splice tray.
What is the Purpose of Buffer tubes in a fiber optic cable?
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?
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?
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?
The fixed V-Groove splicer.
When would a mid-entry splice in a fiber-optic network be used?
, SCORE MORE
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?
A mechanical splice used for acceptance testing should be simple to use and reusable.
What are some prerequisites before performing a fusion splice of optical fibers?
A controlled environment such as a splicing van, trailer or tent and a stable work surface that is large
enough to accommodate the fusion splicer, tools, and the splice closure.
Why are Velcro straps preferred over standard plastic tie wraps when bundling pigtails for storage in a
splice panel?
Because Velcro straps are removable and can hold the pigtails together without placing undue strain on
the optical fibers
When preparing fiber-optic cable for connection to a patch panel, how much buffer tube and fiber slack
should be provided?
Leave enough slack in the buffer tubes to allow the splice trays to reach the splicing equipment and
enough fiber slack to store on individual trays for later additions, moves and changes
If tight-buffered distribution fiber optic cable is installed between the master splice panel in an optical
entrance enclosure (0EE) 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
indoor code requirements for riser or plenum installations.
