Field tech 2-3 Final EXAM 100%Solved

What is unique about WDM - PON ? -Answer WDM-PON deployed in a greenfield system allows each subscriber to get their own designated wavelength. What is the main benefit of deploying WDM technology? -Answer It will increase the capacity of the existing fiber networks tenfold without adding any more fiber. How are optical splitters used in the forward path? -Answer As passive branching devices that divide an optical signal across multiple output fibers. What is the purpose of a fiber demarcation box? -Answer It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics. What is the purpose of the MST? -Answer It provides access to connect fiber-optic cable drops from the customer premises to the network. What is the one main function of the FDH? -Answer The FDH provides effective fiber management by grouping splitters into local serving areas Which PON element uses patch panels? -Answer ODN 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? -Answer Home-Run What are the three categories of the fiber-optic cable used to identify the location of the fiber in the network? -Answer Trunk, branch, and drop. What is the difference between the FTTN and FTTC topologies? -Answer An FTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises. What is the purpose of the SDU? -Answer It provides surge protection, a test jack, circuit protection, wiring management, and fiber termination. What are the advantages of loose buffer tube fiber? -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? -Answer It is a device that converts light from fiber to RF for coaxial distribution into the home. What are the characteristics of ITU-T G.657 BIF? -Answer It is flexible for installation in small spaces and has a small bend
