Answers To Chapter Questions

Chapter 10 Quiz - Installation


    1.    ANS:    T
Electrical noise is often a problem in industrial applications and fiber's immunity is most important.

    2.    ANS:    T
For electrical safety, all conductive parts of the system, including hardware, must be properly grounded and bonded.

    3.    ANS:    F
NEC requires removal of abandoned cables as fire hazards.


    4.    ANS:    D
Cable documentation should be started before installation so the installation is properly documented and ready for labeling and recording test data. Documentation will facilitate installation, allow planning for upgrades and provide data needed for restoration.

    5.    ANS:    D
OSP cables are installed in all these ways which are quite different in process.

    6.    ANS:    A
Eye protection is needed for all installers to prevent fiber scraps from harming the eyes.

    7.    ANS:    B
The rod stiffens the cable to prevent kinking.

    8.    ANS:    A
Pulling ropes sometimes unwind under tension so the swivel prevents it causing cable twists.

    9.    ANS:    D
Each coil in the "figure 8" puts a half-twist into the cable then does a half-twist in the opposite direction to remove any twisting.

    10.    ANS:    C
The guidelines are 20 times the cable diameter under tension, 10 times under no pulling tension.

    11.    ANS:    A
TIA 568, the standard for commercial cabling, covers fiber and copper cabling.

    12.    ANS:    C
The TIA-568 star architecture supports LAN architectures and most other types of equipment connections.

    13.    ANS:    D
Dropping cables from above reduces the stress on the cable and is easier on the installer.

    14.    ANS:    D
Tightening cable ties can put harmful stress on the fibers (or pairs in UTP copper cables), so hand tighten them and cut off the excess length. Even better, use soft "hook and loop" ties that can be reopened to move cables.
