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? -
(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? - (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
