• What is one reason why broadband cable operators install fiber optic
cables in stages 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 FTTN and FTTC . Answer: 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 PON(Passive Optical
Network) . Answer: Optical Splitters


• Which type of Star topology used in a PON(Passive Optical Network)
places the PON splitters into FATS(Fiber Access Terminals) located
deep in the network and closer to the customer premises than the

• 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

optical network (EPON) . Answer: RFoG can operate in parallel with
GPON or EPON, which eliminates the need for any downtime during
the transition
