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
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
When we say 62.5/125 fiber, what does "62.5" mean? Answer core size, the diameter in
microns
When we say 50/125 fiber, what does "125" mean? Answer cladding size, the diameter
in microns
OM3 and OM4 multimode fiber with a 50/125 micron core is very popular in premises
cabling systems today because they _____. - Answer Are "laser optimized" which gives
more distance capability with gigabit networks using laser sources
The attenuation (reduction in optical power) of the fiber in-multimode fiber is _____ at
850 nm than at 1300 nm. - Answer Higher
Which of the following represents a singlemode (smaller core size) fiber size? - Answer
9/125 micron
Singlemode fiber has _____ bandwidth than multimode fiber. - Answer greater
Most plastic optical fibers are _____. - Answer large core step-index
, When you strip singlemode or graded index multimode mode glass fiber, you are
removing the ____. - Answer Primary buffer coating
The proper method of pulling optical fiber cables is to attach the pull wire or tape to the
____ of the cable. - Answer Strength members
According to the references hybrid cables are cables that contain ____. - Answer 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? - Answer ribbon
Composite cables According to the references, refer to cables that contain ____> -
Answer both optical fibers and copper conductors
Which optical fiber cables must be grounded? - Answer all cables that contain metallic
elements
Fiber optic cable for use inside a building must _______. - Answer Be rated to meet the
requirements of local building and fire codes
Optical fiber cable whose jacket color is orange generally indicates that the cable
contains _____. Answer Multimode fiber
The premises cable jackets are color-coded usually in what color to indicate singlemode
fiber? Answer Yellow
The premises cable jackets are usually color-coded in what color to indicate
laser-optimized 50/125 OM3 or OM4 fiber? Answer Aqua
