True/False Indicate whether the statement is true or
false.

1.
|
Dust caps are called “dust caps” because they often contain dust, so
once removed, the fiber optic connector needs cleaning before use.
|
|
2.
|
Mode conditioning for multimode fiber testing is done on the launch
cable.
|
Multiple Choice Identify the choice that best completes the
statement or answers the question.
|
|
3.
|
An insertion loss test uses a light source, power meter, mating adapters and
______ reference cable(s).
|
|
4.
|
An OTDR test that tests the installed cable plant including connectors on both
ends needs ______ reference cable(s).
|
|
5.
|
An OTDR test needs ______ reference cable(s) to test splices as the cable
plant is being spliced during installation.
|
|
6.
|
Multimode fiber in the reference cable must match the fiber type/size of the
fiber in the cable plant under test because mismatched fibers _________.
a. | Can cause high loss when transmitting from 62.5/125 micron fiber into 50/125
fiber | b. | Can cause high loss when transmitting from the core of 50/125 fiber into 62.5/125
fiber | c. | Like OM3 and OM4 fibers have different core diameters | d. | Have connectors that
cannot mate in regular mating adapters |
|
|

Reference quality cables are specified by _________.
a. | Tighter tolerance of fiber diameter | b. | Special ceramic connectors | c. | Low insertion loss
when tested with other reference cables | d. | Special cable manufacturing
techniques |
