, 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
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

When we say 62.5/125 fiber, what does "62.5" mean?
core size, the diameter in microns
C
When we say 50/125 fiber, what does "125" mean?
cladding size, the diameter in microns
OM3 and OM4 multimode fiber with a 50/125 micron core are now a popular option in
LO
premises cabling systems because they _____.
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.
YC
Higher
