1. 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? - ANSWER ✓ True
2. The proper method of pulling optical fiber cables is to attach the
pull wire or tape to the ____ of the cable. - ANSWER ✓ Strength
members
3. According to the references, hybrid cables are cables that contain
____. - ANSWER ✓ Both singelmode and multimode optical
fibers
4. What type of fiber cable design allows for large numbers of fibers
with ultra-high density, small size (diameter) and lower cost? -
ANSWER ✓ ribbon
, 5. According to the references, composite cables refer to cables that
contain ____> - ANSWER ✓ both optical fibers and copper
conductors
6. 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? - ANSWER
✓ True
7. When we say 62.5/125 fiber, what does "62.5" mean? - ANSWER
✓ core size, the diameter in microns
8. When we say 50/125 fiber, what does "125" mean? - ANSWER ✓
cladding size, the diameter in microns
9. OM3 and OM4 multimode fiber with a 50/125 micron core are
now a popular option in premises cabling systems because they
_____. - ANSWER ✓ Are "laser optimized" which gives more
distance capability with gigabit networks using laser sources
10. In-multimode fiber, the attenuation (reduction in optical
power) of the fiber is _____ at 850 nm than at 1300 nm. -
ANSWER ✓ Higher
