FOA CFOT Certification Exam

1. A fiber optic inspection microscope can increase the danger of high
powered light sources by focusing the light coming out of a fiber into
your eye. True or False?: True
2. A fiber optic power meter measures absolute power in dBM (dB
referenced to 1 mw) and, when used with a light source, can
measure insertion loss expressed in dB. True or False?: True
3. When we say 62.5/125 fiber, what does "62.5" mean?: core size, the
diameter in microns
4. When we say 50/125 fiber, what does "125" mean?: cladding size, the
diameter in microns
5. OM3 and OM4 multimode fiber with a 50/125 micron core are now a
popular option in premises cabling systems because they .: Are "laser
optimized" which gives more distance capability with gigabit networks using laser sources
6. In-multimode fiber, the attenuation (reduction in optical power) of
the fiber is at 850 nm than at 1300 nm.: Higher
7. Which of the following represents a singlemode (smaller core
size) fiber size?: 9/125 micron
8. Singlemode fiber has bandwidth than
multimode fiber.: greater
9. Most plastic optical fibers are .:
large core step-index
10. When you strip singlemode or graded index
multimode mode glass fiber, you are removing the .: Primary butter
coating
11. The proper method of pulling optical fiber cables is
to attach the pull wire or tape to the of the cable.: Strength
members
12. Acc
ording to the references, hybrid cables are cables that contain .:
Both singelmode and multimode optical fibers
13. What type of fiber cable design allows for large numbers
of fibers with ultra-high density, small size (diameter) and lower
cost?: ribbon

14. According to the references, composite cables refer to cables
that contain
>: both optical fibers and copper conductors
15. Which optical fiber cables must be grounded?: all cables that contain
metallic elements
16. Fiber optic
cable for use inside a building must .: Be rated to meet
the requirements of local building and fire codes
17. Optical fiber cable with a orange colored jacket
generally indicates the cable contains .: Multimode fiber
