REP 1- REP 2 Exam Questions With Correct
Answers (Verified And Updated)
When light strikes a medium at an angle less than the critical angle, what happens to the light? -
Answer✔It is reflected
In a fiber optic cable, what is the purpose of the cladding? - Answer✔To guide the light down
the fiber
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? - Answer✔1550 nm
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? - Answer✔Tweezers
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? - Answer✔The pull in method
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? -
Answer✔With an optical mechanical splice
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? -
Answer✔A reflective star coupler
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? - Answer✔Fiber to the feeder
*FTTF* - Fiber to the neighborhood *FTTN* - Fiber to the curb *FTTC* - and Fiber to the
home *FTTH*
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) - Answer✔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.

customers? - Answer✔A DTA
Which technology enables cable operators to control access to services by encrypting the
programming? - Answer✔Conditional Acess (CA)
What major sources of television programming are available to broadband cable operators? -
Answer✔Over the air, terrestrial microwave, direct cable feed, and local origination
programming
What are the three main elements of a broadband cable network? - Answer✔The headend, the
distribution network composed of coaxial cable and/or fiber optical cable, and the drop at the
customer premises.
In a broadband cable network, what group is responsible for ensuring that the network remains in
smooth running order by dispatching crews to carry out routing system testing, preventative
maintenance, and equipment servicing and replacement? - Answer✔Network operations center
(NOC)
