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
radius of 7.5 mm or 10 mm.
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.
(-25) + (42) + (-62) + (20) =? - answer -25
(17) x (-19) =? - answer -323
-17-(-34)=？ - answer 17
-49 ÷ -7? - answer 7
(20) ÷ (-4) + (-2) x (-10) - (-2) x (7) =? - answer 29
3 6/9 + 6 1/3 + 9 5/9= - answer 19 5/9
7 3/8 ÷7 1/4= - answer 1. 1/58
8.13 X 0.123 =? - answer 0.99999
