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 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.

Heat shrink tubing is installed over the fusion-splice to strengthen and protect it. When
should the heat shrink be installed on the fiber? - answer Before stripping the plastic
coating from the fiber.

Which of these components is used in a passive optical network (PON)? - answer
Optical splitters

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.
