●● 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


●● What 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 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)


●● 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.
