What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once? - 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? - 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)? - 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? - Distributed star. Which element of a passive optical network (PON) uses a Bragg grating filter? - Optical line terminal (OLT). Which element of a passive optical network (PON) uses patch panels? - Optical distribution network (ODN).
