Field tech 2-3 Final Exam 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 2 / 17 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 3 / 17 radius of 7.5 mm or 10 mm.
