Optic Fiber Test Questions and
Answers 100% Pass
Fiber optics is a communication _______ used to transmit information - ✔✔medium
The information travels in the form of light through _________ - ✔✔high-purity glass
Why does Corning fiber optic solutions use glass instead of plastic? - ✔✔Because the
high-purity glass allows for lower loss solutions
When is plastic fiber used? - ✔✔Used to cover short distances (normally under a foot)
What is the unit of measurement for the diameter or a fiber? - ✔✔(um) micron or
micrometer
A coated optical fiber = _____ um - ✔✔250
What unit of measurement is used for cable diameter? - ✔✔(mm) millimeter
1 um = ______ - ✔✔one millionth of a meter
What unit of measurement is used for wavelengths? - ✔✔(nm) nanometer

What is the typical order of a transmission sequence? - ✔✔1. Information is encoded
into electrical signals
2. Electrical signals are converted to digital or analog light signals
3. The light travels through the fiber
4. A detector changes the light signals into electrical signals
5. Electrical signals are decoded into information
What are the three major components of an optical fiber? - ✔✔Core, cladding, coating
What component of the optical fiber carries information in the form of light signals? -
✔✔Core
What component of the optical fiber ensures that the light pulses remain in the core? -
✔✔Cladding
What is the core typically made out of? - ✔✔Pure silica, but Germania is added to
change the glass properties
