NCTI Field Tech 2 to 3 100% SOLUTION 2023//2024 What is one reason why broadband cable operators install fiber optic cables 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 FTTN and FTTC - ANSWER 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 PON(Passive Optica...

What are three principle characteristics that define an AC waveform? - Answer- The three principle characteristics that define an AC waveform are: (1) frequency; (2) wavelength; and (3) amplitude. What is one of the basic principles of resistance reflected in the familiar practices of grounding and bonding? - Answer- Grounding and bonding practices reflect the basic principle that electricity always follows the path of least resistance. What comprises the impedance of a coaxial cable or a ...

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...

1. What is unique about WDM - PON ?: WDM-PON deployed in a greenfield system allows each subscriber to get their own designated wavelength. 2. What is the main benefit of deploying WDM technology?: It will increase the capacity of the existing fiber networks tenfold without adding any more fiber. 3. How are optical splitters used in the forward path?: As passive branching devices that divide an optical signal across multiple output fibers. 4. What is the purpose of a fiber demarcation box?...
