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,

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
