Fiber-to-the-x or fiber-to-the-user has been used as an all-inclusive
(FTTx) multipurpose
abbreviation for different network
topologies
within the fiber-optic cable network
architecture.
HFC NETWORK In an HFC network, 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.
fiber-to-the-node (FTTN) when the fiber runs between the headend
or hub
to a node
A location or device where optical signals
are
transformed to electrical (RF) signals, or
electrical
signals are transformed to optical signals.
, the x in FTTx is replaced with an "N,"
,which of the following is a they enable a gradual transition to all fiber
characteristic of HFC optic
architectures? cable infrastructure
There is no standard naming FTTN, fiber-to-the-curb (FTTC) and
convention for all the different fiber-to-the-
FTTx premises (FTTP)
topologies. However, almost all fall
within three general categories:
The FTTN topology (defined by brings fiber-optic cable into an area or
some as neighborhood of up to 2,500 customer
fiber-to-the-neighborhood) premises,
terminating the fiber into optical nodes.
FTTC HEADEND--OPTICAL
SPLITTER--DPRON
FTTP HEADENND--OPTICAL SPLITTER
A passive optical network (PON) The technology makes it possible to
deliver data
rates exceeding one gigabit per second
(Gbps).
uses fiber-to-the-premises (FTTP)
topologies to
make a point-to-multipoint (P2MP)
The term "passive" means that light waves in the network are
transported,
split, combined, multiplexed (mux) and
demultiplexed (demux)
, Which of the following is true PON architectures reduce fiber counts.
regarding a PON? Choose all that PON architecture uses optical splitters.
apply.
________________ is spliced into Fiber-optic drop cable
the legs of
an optical splitter and then routed
to
the customer premises.
Sometimes called the feeder or TRUNK
backbone, the ____________ is
the main
optical cable routed from the
headend into the ODN.
____________ fiber-optic cable BRANCH
provides
the intermediate link between the
trunk and drop cables.
Distributed split topology The OLT port is connected directly to the
outside
plant. The first level of PON splitters is
placed into
the FAT located deep in the network. The
second
level of PON splitters is located at the
MST, which
is very close to the customer.
