Fttx basics conventional Final Exam 2023.What is one reason why broadband cable operators install a 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 of these components is used in a passive optical network? - 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? - 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 element (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
