ACTUAL EXAM QUESTIONS AND CORRECT
ANSWERS ALREADY GRADED A+
the applications of optical fiber communications have increased at
a rapid rate, since the first commercial instillation of a fiber optic
system in the Correct Answer 1970's
When we say 62.5/125 fiber, what does "62.5" mean? Correct
Answer core size, the diameter in microns
What type of fiber cable design allows for large numbers of fibers
with ultra-high density, small size (diameter) and lower cost?
Correct Answer ribbon
According to the references, composite cables refer to cables that
contain ____> Correct Answer both optical fibers and copper
conductors
Which optical fiber cables must be grounded? Correct Answer all
cables that contain metallic elements
,Fiber optic cable for use inside a building must _______. Correct
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 _____. Correct Answer Multimode
fiber
Premises cable jackets are usually color-coded in what color to
indicate singlemode fiber? Correct Answer Yellow
Premises cable jackets are usually color-coded in what color to
indicate laser-optimized 50/125 OM3 or OM4 fiber? Correct
Answer Aqua
When we say 50/125 fiber, what does "125" mean? Correct
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
_____. Correct 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. Correct Answer
Higher
, Which of the following represents a singlemode (smaller core
size) fiber size? Correct Answer 9/125 micron
Singlemode fiber has _____ bandwidth than multimode fiber.
Correct Answer greater
Most plastic optical fibers are _____. Correct Answer large core
step-index
When you strip singlemode or graded index multimode mode
glass fiber, you are removing the ____. Correct 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. Correct Answer Strength
members
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? Correct Answer True
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? Correct
Answer True
