INSIGHTS
◉ 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
