FTTX Elements Practice Questions with 100%
Correct Answers
Why do broadband cable operators install fiber-optic cable in stages?
It can be quite costly to lay that much F/O cable at once, so they seek a gradual, staged
transition to an all-fiber network, like with several HFC (Hybrid Fiber Coax) topologies.
HFC Network
A network using a fiber trunk design and coaxial distribution network; a cable system
constructed of both fiber (in the trunk) and coaxial cable (in the feeder and drop); a hybrid
system using a fiber-optic backbone and coaxial cables for final distribution from the node to
the customer.
Star Network Architecture w/ Point-to-Multipoint(P2MP)
Progression of FTTx networks
FTTN (Fiber to the Node)--> FTTC (Fiber to the Curb) --> FTTP/FTTH (Fiber to the
Premises/Home)
Hybrid fiber/coax (HFC) network architectures have been developed to enable a
__________ transition to an all fiber-optic cable infrastructure
gradual/staged
The "x" in fiber-to-the-x (FTTx) is used to describe the term ________.
generically
, In a __________,the fiber-optic cable connects the headend or hub to a location where
the light waves are converted to RF signals and distributed to customer premises
through coaxial cable.
HFC Network
Fiber to the Node (FTTN)
Also called fiber-to-the neighborhood, FTTN is a network topology that provides service to
several hundred destinations, providing broadband connection and other data services
through a shared network box, often called a node.
Fiber to the Curb (FTTC)
A network topology that extends optical fiber to the curbside pedestal, feeding an optical
network unit (ONU), serving a cluster of four to 12 homes.
Fiber to the Premises (FTTP)
Also called fiber-to-the-home (FTTH), FTTP is a network topology where fiber-optic cable
extends from the network's point of origin, such as the headend, hub site, or central office
(CO), to the customer premises (residences, apartment buildings, and businesses) to provide
high-speed internet access.
Which has less amplifiers: FTTC or FTTN?
FTTC
WDM-PON deployed in a greenfield system allows each subscriber to get their own
designated wavelength. True or False?
True
