NCTI FIELD TECH 2-3TEST EXAM With Complete Solutions | Latest 2023/2024 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 premise? -- Home-run Which PON element uses patch panels? -- ODN What is the one main function of the FDH? -- The FDH provides effective fiber management by grouping splitters into local serving areas. What is the purpose of the MST? -- 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? -- It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics. How are optical splitters used in the forward path? -- As passive branching devices that divide an optical signal across multiple output fibers. 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. What is unique about WDM-PON? -- WDM-PON deployed in a greenfield system allows each subscriber to get their own designated wavelength. What is the purpose of the SDU? -- It provides surge protection, a test jack, circuit protection, wiring management, and fiber termination. 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. What is an ONU/ONT? -- 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? -- It is flexible for installation in small spaces and has a small bend radius of 7.5 mm or 10mm.
