FOA- FIBER OPTIC CERTIFICATION
EXAM T/F QUESTIONS AND ANSWERS
GRADED A+ 2025/2026
50/125 microns represents a single mode fiber size - ANS False- Single mode fiber is 8/10
microns
Multimode Fiber has a greater bandwidth than single mode fiber - ANS False - Single mode
has less dispersion: more bandwidth
Pulling from the center to the ends is a way of pulling long cables in conduits - ANS True
Large core step-index is the most common in plastic optical fiber - ANS True
No fiber optic cable needs to be grounded - ANS False - any electronic material must be
grounded
The cladding is the portion of the fiber you are removing during stripping - ANS The buffer is
what you take off
Single mode fiber cables are usally color coded in gray - ANS Fase - Yellow
Loose tube may require the instalation of what - ANS Breakout kit

, Composite cables have only fiber - ANS false- they also have copper
Orange cable contains multimode fiber - ANS True
The testing phase of a project is when you do loss/budget anaylisis - ANS False - should be
done in the planning stage
Distribution cables use mass fusion splicing - ANS False- Ribbion cable uses mass fusion
The reference cables that are used during testing must be chosen for their low loss
characteristics - ANS True
Telecom FTTx is typically single mode fiber - ANS True
Unit for measuring bandwidth - ANS GHz
Unit for measuring absoulute power - ANS dBm
Unit for measuring outside jacket - ANS mm or inches
unit for measuring fiber size - ANS ym or microns
Unit for measuring cable length is - ANS Feet or meters
Unit for measuring wavelength - ANS nm or nanometer
