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 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 ...

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?...

Lesson II NCTI STUDY GUIDE question and answers rated A+ 2023 Through what equipment does a signal pass in the downstream path in the tree-and-branch architecture? - correct answer through trunk coax and amplifiers. Line splitters and directional couplers route some of the signal onto additional trunk runs. What is the role of amplifiers? - correct answer boost the power of a signal How do HFC networks divide the broadband cable operator's coverage area? - correct answer divide the broad...
