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
designated fiber for every customer premise? - correct answer Home-run



Which PON element uses patch panels? - correct answer ODN



What is the one main function of the FDH? - correct answer The FDH provides effective fiber
management by grouping splitters into local serving areas.



What is the purpose of the MST? - correct answer It provides access to connect fiber-optic cable drops
from the customer premises to the network.



What is the purpose of a fiber demarcation box? - correct answer It provides a safe place to splice, split,
distribute, store, and cross-connect fiber optics.



How are optical splitters used in the forward path? - correct answer As passive branching devices that
divide an optical signal across multiple output fibers.



What is the main benefit of deploying WDM technology? - correct answer It will increase the capacity of
the existing fiber networks tenfold without adding any more fiber.

,What is unique about WDM-PON? - correct answer WDM-PON deployed in a greenfield system allows
each subscriber to get their own designated wavelength.



What is the purpose of the SDU? - correct answer It provides surge protection, a test jack, circuit
protection, wiring management, and fiber termination.



What are the advantages of loose buffer tube fiber? - correct answer It offers the best protection for the
fibers under high pulling tension and moisture with its fiber-coated gel.



What is an ONU/ONT? - correct answer It is a device that converts light from fiber to Rf for coaxial
distribution into home.



What are the characteristics of ITU-T G.657 BIF? - correct answer It is flexible for installation in small
spaces and has a small bend radius of 7.5 mm or 10mm.



What is true about using a premed fiber-optic pigtail for splicing to patch panels or terminal equipment?
- correct answer It is faster and more reliable than installing connectors in the field.



What is the proper way to handle fiber once it is spliced? - correct answer At the heat-shrink protective
sleeve that has a steel bar inside it.



What is the purpose of the ground block? - correct answer To protect fragile electronics like Tvs and
STBs from damaging lightning strikes and power surges.



In a PON FTTx networks, which OSP device contains fiber test points that will minimize service disruption
to customers? - correct answer FDH.



What parameter is critical in an OTDR when testing a PON with significant splitters losses? - correct
answer High dynamic range.



What is the best approach to repairing an aerial fiber-optic drop cable for FTTx applications? - correct
answer Replace the entire section of fiber drop cable.
