Solved) Questions With Answers.
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
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 premises
cabling systems because they _____. - ✔✔✔ - Are "laser optimized" which gives more distance
capability with gigabit networks using laser sources
