Field Tech II - III Conventional questions with correct answers

What is one reason why broadband cable operators install fiber-optic cable 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 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.
