Ncti field tech 2 to 3 progression final exam 2026
,1. What is unique about WDM - PON ?: WDM-PON deployed in a
greenfieldsystem allows each subscriber to get their own designated wavelength.
2. What is the main benefit of deploying WDM technology?: It will increase
thecapacity of the existing fiber networks tenfold without adding any more fiber.
3. How are optical splitters used in the forward path?: As passive branchingdevices
that divide an optical signal across multiple output fibers.
4. What is the purpose of a fiber demarcation box?: It provides a safe place tosplice, split,
distribute, store, and cross-connect fiber optics.
5. What is the purpose of the MST? : It provides access to connect fiber-optic cabledrops from
the customer premises to the network.
6. What is the one main function of the FDH?: The FDH provides effective
fibermanagement by grouping
splitters into local serving areas
,7. Which PON element uses patch panels?: ODN
8. 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
9. What are the three categories of the fiber-optic cable used to identify the location of the
fiber in the network?: Trunk, branch, and drop.
10. What is the difference between the FTTN and FTTC
topologies?: An FTC is allowed a smaller number of RF amplifiers between the optical fiber
and the customer premises.
11. What is the purpose of the SDU?: It provides surge protection, a test jack,
circuit protection, wiring management, and fiber termination.
12. What are the advantages of loose buffer tube fiber?: It offers the best protection for the fibers
under high pulling tension and moisture with its fiber-coated gel.
13. What is an ONU/ONT?: It is a device that converts light from fiber to RF for coaxial
distribution into the home.
14. What are the characteristics of ITU-T G.657 BIF?: It is flexible for installation in small spaces
and has a small bend
, radius of 7.5 mm or 10 mm.
15. What le true about using a premade fiber-optic pigtail for
splicing to patch panels or terminal equipment?: It is faster and more rellable than installing
eonnectors in the
field.
16. What is the proper way to handle fiber once it is spliced?: At the heat-shrink protective sleeve
that has a steel bar inside it.
