NCTI 2-3 20 Questions Correctly Answered Guaranteed Pass.

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. 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 Trunk, 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.
