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 In-multimode fiber, the attenuation (reduction in optical power) of the fiber is _____ at 850 nm than at 1300 nm. Higher Which of the following represents a singlemode (smaller core size) fiber size? 9/125 micron
