FOA CFOT MULTIPLE-CHOICE EXAM
QUESTIONS WITH COMPLETE
ANSWERS
50/125 microns represents a single mode fiber size - Answer-False- Single mode fiber
is 8/10 microns
Multimode Fiber has a greater bandwidth than single mode fiber - Answer-False - Single
mode has less dispersion: more bandwidth
Pulling from the center to the ends is a way of pulling long cables in conduits - Answer-
True
Large core step-index is the most common in plastic optical fiber - Answer-True
No fiber optic cable needs to be grounded - Answer-False - any electronic material must
be grounded
The cladding is the portion of the fiber you are removing during stripping - Answer-The
buffer is what you take off
Single mode fiber cables are usally color coded in gray - Answer-Fase - Yellow
Loose tube may require the instalation of what - Answer-Breakout kit
Composite cables have only fiber - Answer-false- they also have copper
Orange cable contains multimode fiber - Answer-True
The testing phase of a project is when you do loss/budget anaylisis - Answer-False -
should be done in the planning stage
Distribution cables use mass fusion splicing - Answer-False- Ribbion cable uses mass
fusion
The reference cables that are used during testing must be chosen for their low loss
characteristics - Answer-True
Telecom FTTx is typically single mode fiber - Answer-True
Unit for measuring bandwidth - Answer-GHz
Unit for measuring absoulute power - Answer-dBm
