What is one reason why broadband cable operators install fiber-optic cable in instead of changing the
stages infrastructure all at once? - CORRECT 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? -
CORRECT ANSWER -An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and
the customer premises.
Which of these components used in a passive optical network (PON)? - CORRECT 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? - CORRECT ANSWER -Distributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter? - CORRECT ANSWER -
Optical line terminal (OLT).
Which element of a passive optical network (PON) uses patch panels? - CORRECT 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) architectur over to a gigabit-
capable passive optical network (GPON) or Ethernet passive optical network (EPON)? - CORRECT
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? - CORRECT ANSWER -In the forward path, optical
splitters are used as passive branching devices that divide an optical signal across multiple output fibers.
stages infrastructure all at once? - CORRECT ANSWER -Changing the infrastructure all at once would
cause too many service disruptions.
