FOA- Fiber Optic Certification
Exam T/F QUESTIONS &
ANSWERS(RATED A)
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
Outside cable resistant to rodents - ANSWER Armored cable
The cable that is used indoors in air handling areas is - ANSWER plenum rated cable
Telcom Fttx is typically - ANSWER single mode fiber
The most important safety concern specific to fiber optics is? - ANSWER Shards of bare fibers getting
stuck in skin or eyes.
Whenever working with fiber you should? - ANSWER wear safety glasses at all times, clear the work area
of food and scraps, and dispose of fiber scraps in a sealed container.
You should never look directly at the end of a fiber without checking for optical power with a power
meter because some fiber optic networks have high enough power to cause eye damage. - ANSWER True
Fusion Splicers should not be used - ANSWER in places that may contain flammable gasses
For safety, all fiber optic work areas must - ANSWER have sufficient work space
