What is one reason why broadband cable operators install fiber-optic cable in stages
instead of changing the infrastructure all at once? - AnswerChanging 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? - AnswerAn 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? - AnswerDistributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter? -
AnswerOptical line terminal (OLT).
Which element of a passive optical network (PON) uses patch panels? - AnswerOptical
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)? - AnswerRFoG 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? - AnswerIn 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? - AnswerFiber-optic cable with pre-
connectorized ends.
Heat shrink tubing is installed over the fusion-splice to strengthen and protect it. When

coating from the fiber.
Which of these components is used in a passive optical network (PON)? -
AnswerOptical splitters
