Solutions Field tech 2-3 Final 200Q/A
What is unique about WDM - PON ?
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?
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?
As passive branching devices that divide an optical signal across multiple output fibers.
What is the purpose of a fiber demarcation box?
It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics.
What is the purpose of the MST?
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?
The FDH provides effective fiber management by grouping
splitters into local serving areas
Which PON element uses patch panels?
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?
Home-Run
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.
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.
,What is the purpose of the SDU?
It provides surge protection, a test jack, circuit protection, wiring management, and fiber termination.
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.
What is an ONU/ONT?
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?
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?
It is faster and more rellable than installing eonnectors in the
field.
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.
What is the purpose of the ground block?
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?
FDH (Fiber Distribution Hub)
What parameter is critical in an OTDR when testing a PON with
significant splitters losses?
High Dynamic Range
What is the best approach to repairing an aerial fiber-optic
drop cable for FTTx applications?
Replace the entire section of fiber drop cable.

4,431.606
0.00004= ——- × 10 to the power of ——?
4,-5
What is the square of 7?
49
Which of the statements is true of axioms?
When A = C and B = C, then A = B because both are equal to C,
which supports the axiom: Quantities equal to the same quantity
are equal to each other.
Simplify and solve the equation: If E = IR, then | =?
E/R
What is the square root of 81?
9
0.00004= —— × 10 to the power of —— ?
