Ncti 2-3 Questions and Answers 2023 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 pre...

Field Tech II - III Conventional – NCTI Questions and Answers 2023 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 premi...

NCTI Installer Tech/November question with complete solution 2023Why do only the outer electrons leave their orbit shells? - correct answer Only outer electrons leave their orbit shells because electrons farthest from the nucleus are more easily freed from their orbits due to a weaker electrostatic force. What is required to have a balanced (or stable) atom? - correct answer The number of electrons must equal the number of protons in order to have a balanced atom. List the capacity of each...
