, 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
