Exam Questions With Correct Answers
What is one reason why broadband cable operators install fiber-optic cable in stages instead of
changing the infrastructure all at once? - answer✔Changing the infrastructure all at once would
cause too many service disruptions.
What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC)
topologies? - answer✔An FTTC is allowed a smaller number of RF amplifiers between the
optical fiber and the customer premises.
Which of these components is used in a passive optical network (PON)? - answer✔Optical
splitters.
Which type of star topology used in a passive optical network (PON) places the PON splitters
into fiber access terminal (FAT) located deep in the network and closer to the customer premises
than the centralized split? - answer✔Distributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter? -
answer✔Optical line terminal (OLT).
Which element of a passive optical network (PON) uses patch panels? - answer✔Optical
distribution network (ODN).
What is it about radio frequency over glass (RFoG) that made broadband cable operators
envision using it to make a seamless transition from the legacy hybrid fiber/coax (HFC)
architecture over to a gigabit-capable passive optical network (GPON) or Ethernet passive
optical network (EPON)? - answer✔RFoG can operate in parallel with GPON or EPON, which
eliminates the need for any downtime during the transition.
How are optical splitters used in the forward path? - answer✔In the forward path, optical
splitters are used as passive branching devices that divide an optical signal across multiple output
fibers.
Which of the following describes a fiber pigtail? - answer✔Fiber-optic cable with pre-
connectorized ends.
Which of the following are statements of true axioms? - answer✔When A = C and B = C, then
A = B because both are equal to C, which supports the axiom: Quantities equal to the same
quantity are equal to each other.
Simplify and solve the equation: If E = IR then I = ? - answer✔E/R

4
10 to the power of -3 has a metric prefix of ______. - answer✔Milli
(480 x 10 to the power of -5) divided by (60 x 10 to the power of -3) = - answer✔8 x 10 to the
power of -2
(250 x 10 to the power of -6) - (7 x 10 to the power of -5) = - answer✔180 x 10 to the power of
-6
