Questions with 100% Correct Answers |
Latest Update
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.

✔✔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.

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.
