ANSWERS(GRADED A+)
What is unique about WDM - PON ? - ANSWER WDM-PON deployed in a greenfield
system allows eac.h subscriber to get their own designated wavelength.
What is the main benefit of deploying WDM technology?1 - 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.

management by grouping
splitters into local serving areas

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.

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 le true about using a premade fiber-optic pigtail for
splicing to patch panels or terminal equipment? - ANSWER It is faster and more rellable
than installing eonnectors in the
field.
What is the proper way to handle fiber once it is spliced? - ANSWER At the heat-shrink
protective sleeve that has a steel bar inside it.
What is the purpose of the ground block? - ANSWER To protect fragile electronics like
TV's and STBs from damaging lightning strikes and power surges.
In a PON FTTx network, which OSP device contains fiber test
points that will minimize service disruption to customers? - ANSWER FDH (Fiber
Distribution Hub)
What parameter is critical in an OTDR when testing a PON with
significant splitters losses? - ANSWER High Dynamic Range
What is the best approach to repairing an aerial fiber-optic
drop cable for FTTx applications? - ANSWER Replace the entire section of fiber drop
cable.

Why should you take the time to take notes
and accurately record data at each job
location? - ANSWER Notes and recorded data are tools that can help you accurately
remember events at a site that can help you determine a plan of action or evaluate the
decisions you made.
