Chapter 1 Quiz-Basic
1. ANS: T
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
greater bandwidth and lower attenuation of fiber allows it to carry
more signals further without regeneration, making it considerably less
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

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