Answers To Chapter Questions

Chapter 1 Quiz-Basic


    1.    ANS:    T
Since most OSP installs are longer links, SM is the fiber of choice. Some utilities and municipal networks can use MM fiber, but it's less common.

    2.    ANS:    T
Most premises cables are simple single cable runs, terminated on each end.

    3.    ANS:    T
The greater bandwidth and lower attenuation of fiber allows it to carry more signals further without regeneration, making it considerably less expensive.

    4.    ANS:    F
Most fiber systems and test equipment use infrared light which is invisible to the human eye.

    5.    ANS:    T
Most airborne dirt is hard enough to scratch the ends of fibers in physical-contact connectors.


    6.    ANS:    D
All these types of installations are possible in the OSP.

    7.    ANS:    C
Moisture is a problem in all OSP cables.

    8.    ANS:    A
Armoring can stop rodents from harming cables.

    9.    ANS:    B
Fusion splicing is the most reliable method of joining cables.

    10.    ANS:    C
Backbones often use both fiber types - MM to carry today's traffic and SM for future expansion.

    11.    ANS:    D
Any cable installed indoors must be rated for fire retardance to meet electrical and building codes.

    12.    ANS:    A
The biggest danger in fiber installs is getting fiber scraps in your eyes.

    13.    ANS:    B
You should consult Material Safety Data Sheets for all chemicals (solvents, cleaners, adhesives, etc.) used in fiber installations.

    14.    ANS:    D
