Name: Score:30 Multiple choice questions
Term 1 of 30
What is the proper way to handle fiber once it is spliced?
It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics.
An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the
customer premises.
It will increase the capacity of the existing fiber networks tenfold without adding any
more fiber.
At the heat-shrink protective sleeve that has a steel bar inside it.
Term 2 of 30
What is the purpose of the MST?
It provides access to connect fiber-optic cable drops from the customer premises to the
network.
It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics.
To protect fragile electronics like TVs and STBs from damaging lightning strikes and
power surges.
It provides surge protection, a test jack, circuit protection, wiring management, and fiber
termination.
,Term 3 of 30
What are the benefits of using a fiber splicing tray?
It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics.
It stores slack and spliced fiber and prevents fiber cables from being misplaced or
damaged.
It offers the best protection for the fibers under high pulling tension and moisture with its
fiber-coated gel.
It enables up to 18 channels for transmitting and receiving 18 kinds of signals, with
wavelengths from 1270 nm to 1610 nm.
Term 4 of 30
What is an ONU/ONT?
It provides access to connect fiber-optic cable drops from the customer premises to the
network.
It provides surge protection, a test jack, circuit protection, wiring management, and fiber
termination.
It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics.
It is a device that converts light from fiber to RF for coaxial distribution into the home.
Term 5 of 30
In a PON FTTx network, which OSP device contains fiber test points that will minimize service
disruption to customers?
Odn.
Home-run.
FDH.
Olt.
,Term 6 of 30
What is the one main function of the FDH?
To protect fragile electronics like TVs and STBs from damaging lightning strikes and
power surges.
The FDH provides effective fiber management by grouping splitters into local serving
areas.
It provides access to connect fiber-optic cable drops from the customer premises to the
network.
It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics.
Term 7 of 30
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?
Fdh.
Centralized Split.
Star-bus.
Home-run.
Term 8 of 30
What is the difference between the FTTN and FTTC topologies?
It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics.
At the heat-shrink protective sleeve that has a steel bar inside it.
An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the
customer premises.
It will increase the capacity of the existing fiber networks tenfold without adding any
more fiber.
, Term 9 of 30
Why did broadband cable operators envision using RFoG to make a seamless transition from
the legacy HFC architecture over to a gigabit-capable passive optical network (GPON) or
Ethernet passive optical network (EPON)?
Always wear safety glasses and special protective gloves and dispose of cut fiber shards
in a designated container.
RFoG can operate in parallel with GPON or EPON, which eliminates the need for any
downtime during the transition.
It is faster and more reliable than installing connectors in the field.
It offers the best protection for the fibers under high pulling tension and moisture with its
fiber-coated gel.
Term 10 of 30
What is the purpose of a fiber demarcation box?
To protect fragile electronics like TVs and STBs from damaging lightning strikes and
power surges.
It provides access to connect fiber-optic cable drops from the customer premises to the
network.
It provides surge protection, a test jack, circuit protection, wiring management, and fiber
termination.
It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics.
Term 11 of 30
What are the three categories of the fiber-optic cable used to identify the location of the fiber
in the network?
Tree, mainline, and node.
Home-run.
Fiber-optic cable with pre-connectorized ends.
Trunk, branch, and drop.
