FOA CFOT CERTIFICATION
EXAM
During fiber optic installations, the most common danger is caused by
______. - ANSWERS-Fiber scraps or shards from stripping, cleaving,
splicing and termination
The link loss budget analysis of a cable plant like the diagram shown
is done to _________. - ANSWERS-All of these choices (Ensure the
intended communications system will work on the cable plant system,
Provide a pass/fail loss value for comparison to test values, Ensure the
cable plant has been properly installed)
A link loss budget should be done for every cable plant installation
during the ______ phase of a project. - ANSWERS-Design
The loss of connector on each end of the cable plant ______. -
ANSWERS-Are always included in the loss budget
Cladding - ANSWERS-Material around the center tube (Look at
diagram)
Core - ANSWERS-Center tube (Look at diagram)
Primary Buffer Coating - ANSWERS-Material around the core and
cladding, it gives the fiber its distinct color (Blue, Red, Agua, etc)
, Traps light in the core to reduce attenuation - ANSWERS-Cladding
Is smaller in singlemode than multimode fiber - ANSWERS-Core
Is stripped off for termination or splicing - ANSWERS-Primary
Buffer Coating
The outside diameter of this part of the fiber is the same for most
singlemode and multimode fibers - ANSWERS-Cladding
Singlemode - ANSWERS-
Multi-mode graded index - ANSWERS-
Multi-mode step index - ANSWERS-
Telecom outside plant - ANSWERS-Singlemode
Telecom FTTx - ANSWERS-Singlemode
CATV hybrid fiber coax network - ANSWERS-Singlemode
LAN fiber to the desk - ANSWERS-Multimode Graded-Index
