What is the difference between the FTTN and FTTC topologies? -
Correct Answer - An FTTC is allowed a smaller number of RF
amplifiers between the optical fiber and the customer premises.
What are the three categories of the fiber-optic cable used to
identify the location of the fiber in the network? - Correct Answer
- Truck, branch, and drop
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? - Correct Answer - Home-run
Which PON element uses patch panels? - Correct Answer -
ODN
,What is the one main function of the FDH? - Correct Answer -
The FDH provides effective fiber management by grouping
splitters into local serving areas.
What is the purpose of the MST? - Correct Answer - It provides
access to connect fiber-optic cable drops from the customer
premises to the network.
What is the purpose of a fiber demarcation box? - Correct
Answer - It provides a safe place to splice, split, distribute, store,
and cross-connect fiber optics.
How are optical splitters used in the forward path? - Correct
Answer - As passive branching devices that divide an optical
signal across multiple output fibers.
What is the main benefit of deploying WDM technology? -
Correct Answer - It will increase the capacity of the existing fiber
networks tenfold without adding any more fiber.
,What is unique about WDM-PON? - Correct Answer - WDM-
PON deployed in a greenfield system allows each subscriber to
get their own designated wavelength.
What is the purpose of the SDU? - Correct Answer - It provides
surge protection, a test jack, circuit protection, wiring
management, and fiber termination.
What are the advantages of loose buffer tube fiber? - Correct
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? - Correct Answer - It is a device that
converts light from fiber to Rf for coaxial distribution into home.
What are the characteristics of ITU-T G.657 BIF? - Correct
Answer - It is flexible for installation in small spaces and has a
small bend radius of 7.5 mm or 10mm.
, What is true about using a premed fiber-optic pigtail for splicing to
patch panels or terminal equipment? - Correct Answer - It is
faster and more reliable than installing connectors in the field.
What is the proper way to handle fiber once it is spliced? -
Correct Answer - At the heat-shrink protective sleeve that has a
steel bar inside it.
What is the purpose of the ground block? - Correct Answer - To
protect fragile electronics like Tvs and STBs from damaging
lightning strikes and power surges.
In a PON FTTx networks, which OSP device contains fiber test
points that will minimize service disruption to customers? -
Correct Answer - FDH.
What parameter is critical in an OTDR when testing a PON with
significant splitters losses? - Correct Answer - High dynamic
range.
