Quiz: What is unique about WDM - PON ?, Ans: 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?, Ans: 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?, Ans: As passive branching
devices that divide an optical signal across multiple output fibers.
What is the purpose of a fiber demarcation box?, Ans: It provides a safe place
to splice, split, distribute, store, and cross-connect fiber optics.
What is the purpose of the MST?, Ans: 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?, Ans: The FDH provides effective
fiber management by grouping
splitters into local serving areas

,Which PON element uses patch panels?, Ans: 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?, Ans: Home-Run
What are the three categories of the fiber-optic cable used to identify the
location of the fiber in the network?, Ans: Trunk, branch, and drop.
What is the difference between the FTTN and FTTC
topologies?, Ans: 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?, Ans: It provides surge protection, a test jack,
circuit protection, wiring management, and fiber termination.
What are the advantages of loose buffer tube fiber?, Ans: It offers the best
protection for the fibers under high pulling tension and moisture with its fiber-
coated gel.
What is an ONU/ONT?, Ans: 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?, Ans: 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?, Ans: It is faster and more
rellable than installing eonnectors in the
field.
What is the proper way to handle fiber once it is spliced?, Ans: At the heat-
shrink protective sleeve that has a steel bar inside it.
What is the purpose of the ground block?, Ans: 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?, Ans: FDH (Fiber
Distribution Hub)
What parameter is critical in an OTDR when testing a PON with
significant splitters losses?, Ans: High Dynamic Range

7 3/8 ÷7 1/4=, Ans: 1. 1/58
8.13 X 0.123 =?, Ans: 0.99999
0.5349 ÷ 0.1420?, Ans: 3.7669014
67.84 + 81.786 + 4281.98 = ?, Ans: 4,431.606
