What is one reason why broadband cable operators install
fiber-optic cable in stages instead of changing the
infrastructure all at once? Ans: 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? Ans: 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)? Ans: 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? Ans:
Distributed star.
Which element of a passive optical network (PON) uses a
Bragg grating filter? Ans: Optical line terminal (OLT).
Which element of a passive optical network (PON) uses
patch panels? Ans: 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)? Ans: 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? Ans:
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? Ans:
Fiber-optic cable with pre-connectorized ends.
Heat shrink tubing is installed over the fusion-splice to
strengthen and protect it. When should the heat shrink
be installed on the fiber? Ans: Before stripping the plastic
coating from the fiber.
Which of the following are statements of true axioms?
Ans: 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 = ? Ans:
E/R

3 6/9 + 6 1/3 + 9 5/9 = Ans: 19 5/9
4/7 x 9 4/11 = Ans: 5 27/77
7 3/8 divided by 7 1/4 = Ans: 1 1/58
8.13 X 0.123 = Ans: 0.99999
