FTTx Basics, NCTI FTTx Basics
Conventional Exam Review Exam
Questions and Answers 100% Pass
What is the difference between the FTTN and FTTC topologies? - ✔✔An FTTC is
allowed a smaller number of RF amplifiers between the optical fiber and the customer
premises.
What are the three categories of fiber-optic cable used to identify the location of the
fiber in the network? - ✔✔Trunk, branch, and drop
Which PON element uses patch panels ? - ✔✔ODN
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 purpose of a fiber demarcation box? - ✔✔It provides a safe place to splice,
split, distribute, store, and cross-connect fiber optics.
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 main benefit of deploying WDM technology? - ✔✔It will increase the
capacity of the existing fiber networks tenfold without adding any more fiber

, 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 best approach to repairing an aerial fiber-optic drop cable for FTTx
applications? - ✔✔Replace the entire section of fiber drop cable.
What is the purpose of the SDU? - ✔✔It provides surge protection, a test jack, circuit
protection, wiring management, and fiber termination.
What are some of 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 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 10mm.
What is true about using premade fiber-optic pigtail for splicing to patch panels or
terminal equipment? - ✔✔It is faster and more reliable than installing connectors 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 a ground block? - ✔✔To protect fragile electronics like Tvs and
STBs from damaging lightning strikes and power surges.
In a PON FTTx network, which OSP device contains fiber test points that minimize
service disruption to customers? - ✔✔FDH.
