CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS)
QUESTION: When light strikes a medium at an angle less than the
critical angle, what happens to the light?
Ans: It is reflected
QUESTION: In a fiber optic cable, what is the purpose of the
cladding?
Ans: To guide the light down the fiber
QUESTION: You are planning a fiber optic network and want to
amplify the signal so you can send it farther into the field. At which
wavelength must the laser emit?
Ans: 1550 nm
QUESTION: It is important to follow safety procedures when
installing and handling fiber optic cable. What should you use to
pick up fiber pieces after you splice a cable?

Ans: Tweezers
QUESTION: You are doing an aerial installation of fiber optic cable.
When you survey the installation path, you see that the path runs
near several short outbuildings and over a series of hedges. Which
installation method should you use?
Ans: The pull in method
QUESTION: Poor performance in the fiber optic network leads you
to believe that there is a fault in the fiber optic cable and you want
to test a section of the network with an optical time domain
reflectometer OTDR, How should you connect the OTDR to the fiber
optic cable?
Ans: With an optical mechanical splice
QUESTION: As you prepare to set up the fiber optic network, you
realize you need a coupler that will allow any of its ports to be used
as either input or output. Which coupler should you choose?

Ans: A reflective star coupler
QUESTION: As cable companies have expanded their use of fiber
optic cable, they have also brought it closer to the customer
premises, increasing the bandwidth available to customers. Which
answer below represents the progression of fiber optic network
architecture?
Ans: Fiber to the feeder *FTTF* - Fiber to the neighborhood *FTTN* - Fiber to the
curb *FTTC* - and Fiber to the home *FTTH*
QUESTION: Why is the broadband cable industry developing its own
passive optical network (PON) standard instead of using standards
already developed by the International Telecommunication Union
(ITU) and the Institute of Electrical and Electronics Engineers (IEEE)
Ans: The industry has invested a lot of money in HFC Networks, Data Over Cable
Service Interface Specification, and other systems and devices that are still
currently being used, but they are not compatible with ITU and IEEE PON
standards.
