FOA CFOT CERT EXAM 2025 V11 QUESTIONS
AND CORRECT ANSWERS GRADED A+
If you need to permanently join two fibers together with the lowest loss and least
amount of reflectance, which of the following should you choose?
fusion splice
Mass fusion splicing is normally used on what style of cable?
ribbon cable
Prior to cable plant acceptance or system turn-up, a(n) _____ is used to measure
the cable plant insertion loss to ensure it is within the loss budget.
Light source and power meter (LSPM or OLTS)
For insertion loss testing, the fiber optic test source must match the _____ of the
transmission system or the standards covering the cable plant.
both fiber type and wavelenght
,According to the text, it is recommended that reference test cables be chosen for
their __________>
low loss
Which of the following parameters cannot be measured by OTDRs (optical time
domain reflectometers) in fiber optic networks.
Transmitter and receiver power
For safety, a fiber optic technician or installer should always wear ______ when
working with optical fiber.
Eye protection
During fiber optic installations, the most common danger is caused by ______.
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
_________.
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.
Design
The loss of connector on each end of the cable plant ______.
Are always included in the loss budget
Cladding
Material around the center tube (Look at diagram)
Core
Center tube (Look at diagram)
Primary Buffer Coating
Material around the core and cladding, it gives the fiber its distinct color (Blue,
Red, Agua, etc)
