FOA CFOT Certification V11 Exam With 100 Questions &
Correct Answers
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? - ANSWER-True
When we say 62.5/125 fiber, what does "62.5" mean? - ANSWER-core size, the
diameter in microns
When we say 50/125 fiber, what does "125" mean? - ANSWER-cladding size, the
diameter in microns
OM3 and OM4 multimode fiber with a 50/125 micron core are now a popular
option in premises cabling systems because they _____. - ANSWER-Are "laser
optimized" which gives more distance capability with gigabit networks using laser
sources
In-multimode fiber, the attenuation (reduction in optical power) of the fiber is
_____ at 850 nm than at 1300 nm. - ANSWER-Higher
Which of the following represents a singlemode (smaller core size) fiber size? -
ANSWER-9/125 micron
Singlemode fiber has _____ bandwidth than multimode fiber. - ANSWER-greater
Most plastic optical fibers are _____. - ANSWER-large core step-index
, When you strip singlemode or graded index multimode mode glass fiber, you are
removing the ____. - ANSWER-Primary buffer coating
The proper method of pulling optical fiber cables is to attach the pull wire or tape
to the ____ of the cable. - ANSWER-Strength members
According to the references, hybrid cables are cables that contain ____. -
ANSWER-Both singelmode and multimode optical fibers
What type of fiber cable design allows for large numbers of fibers with ultra-high
density, small size (diameter) and lower cost? - ANSWER-ribbon
According to the references, composite cables refer to cables that contain ____> -
ANSWER-both optical fibers and copper conductors
Which optical fiber cables must be grounded? - ANSWER-all cables that contain
metallic elements
Fiber optic cable for use inside a building must _______. - ANSWER-Be rated to
meet the requirements of local building and fire codes
Optical fiber cable with a orange colored jacket generally indicates the cable
contains _____. - ANSWER-Multimode fiber
Premises cable jackets are usually color-coded in what color to indicate
singlemode fiber? - ANSWER-Yellow
Premises cable jackets are usually color-coded in what color to indicate laser-
optimized 50/125 OM3 or OM4 fiber? - ANSWER-Aqua
