NCTI Installer Tech 100% SOLUTIONS REVISED 2023//2024 Why do only the outer electrons leave their orbit shells? - 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? - ANSWER The number of electrons must equal the number of protons in order to have a balanced atom. List the capacity of each of the first four or...

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 2-3 question and answers graded 2023 passed What is the difference between the FTTN and FTTC topologies? - correct answer 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? - correct answer Truck, branch, and drop Which type of fiber topology used in a PON places the PON splitters at the headend while providing one...

NCTI WIFI QUESTIONS AND ANSWERS 2023 Notes Single input, single output (SISO) - Most systems have one radio and one antenna, and some systems have one radio and two antennas. Multiple input, multiple output (MIMO) - These systems use multiple radio chains in a single wireless chipset. Multi-user MIMO (MU-MIMO) - These systems use each radio chain on an access point to transmit to a unique client.Correct answer: Wired Equivalent Protection (WEP) - This type of security setup should never be ...

NCTI Service Technician: Think About it correctly answered to pass 2023What are three principle characteristics that define an AC waveform? - correct 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? - correct answer Grounding and bonding practices reflect the basic principle that electricity always follows t...

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?...
