NCTI 2-3 Questions and Answers 100% Pass What is the difference between the FTTN and FTTC topologies? An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises. What are the three categories of the fiber-optic cable used to identify the location of the fiber in the network? Truck, branch, and drop Which type of fiber topology used in a PON places the PON splitters at the headend while providing one designated fiber for every customer premise? Home-run Which PON element uses patch panels? ODN What is the one main function of the FDH? The FDH provides effective fiber management by grouping splitters into local serving areas. What is the purpose of the MST? It provides access to connect fiber-optic cable drops from the customer premises to the network. What is the purpose of a fiber demarcation box?
