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
radius of 7.5 mm or 10 mm.
15. What le true about using a premade fiber-optic pigtail for
splicing to patch panels or terminal equipment?: It is faster and more rellable
than installing eonnectors in the
field.
16. What is the proper way to handle fiber once it is spliced?: At the heat-shrink
protective sleeve that has a steel bar inside it.

points that will minimize service disruption to customers?: FDH (Fiber Distrib-
ution Hub)
19. What parameter is critical in an OTDR when testing a PON with
significant splitters losses?: High Dynamic Range
20. What is the best approach to repairing an aerial fiber-optic
drop cable for FTTx applications?: Replace the entire section of fiber drop cable.

and accurately record data at each job
location?: Notes and recorded data are tools that can help you accurately remem-
ber events at a site that can help you determine a plan of action or evaluate the
decisions you made.
