Questions and CORRECT Answers
A fiber optic inspection microscope can increase the True
danger of high powered light sources by focusing the
light coming out of a fiber into your eye. True or False?
A fiber optic power meter measures absolute power in True
dBM (dB referenced to 1 mw) and, when used with a
light source, can measure insertion loss expressed in
dB. True or False?
When we say 62.5/125 fiber, what does "62.5" mean? core size, the diameter in microns
, 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 Are "laser optimized" which gives more distance capability with gigabit
