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? Ans✓✓✓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? Ans✓✓✓True
When we say 62.5/125 fiber, what does "62.5" mean? Ans✓✓✓core
size, the diameter in microns
When we say 50/125 fiber, what does "125" mean? Ans✓✓✓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 _____.
Ans✓✓✓Are "laser optimized" which gives more distance capability

fiber is _____ at 850 nm than at 1300 nm. Ans✓✓✓Higher
, Which of the following represents a singlemode (smaller core size) fiber
size? Ans✓✓✓9/125 micron
Singlemode fiber has _____ bandwidth than multimode fiber.
Ans✓✓✓greater
Most plastic optical fibers are _____. Ans✓✓✓large core step-index
When you strip singlemode or graded index multimode mode glass fiber,
you are removing the ____. Ans✓✓✓Primary buffer coating
The proper method of pulling optical fiber cables is to attach the pull
wire or tape to the ____ of the cable. Ans✓✓✓Strength members
According to the references, hybrid cables are cables that contain ____.
Ans✓✓✓Both singelmode and multimode optical fibers
What type of fiber cable design allows for large numbers of fibers with
ultra-high density, small size (diameter) and lower cost?
Ans✓✓✓ribbon
According to the references, composite cables refer to cables that
contain ____> Ans✓✓✓both optical fibers and copper conductors
