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? correct 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? correct answer: True When we say 62.5/125 fiber, what does "62.5" mean? correct answer: core size, the diameter in microns Wh...
