Built-in EQAM
l
The edge quadrature amplitude modulation (EQAM) feature enables
the MA5633 to function as the gateway of a hybrid fiber coaxial
(HFC) network connected to an IP network. The MA5633
multiplexes and modulates IP signals into radio frequency (RF)
signals so that the data carried in the IP signals can be transmitted
over the HFC network.
l
The EQAM built in the MA5633 is moved downwards from the
branch equipment room to the fiber node. Therefore, the fiber node
does not require an additional EQAM.
l
Video streams are transmitted over a MAN network through the OLT
to the MA5633. The MA5633 uses the built-in EQAM to module the
video signals into RF signals and sends the RF signals to the STB.
Splitter
A component that connects to the center of a branch or feeder fiber. It
consists of a main input end, a main output end, and multiple branch
output ends. Each branch output end receives only few input signals on
the main path. The majority signals are transmitted forward over the
main path.

Description
PON
A passive optical network (PON) uses a point-to-multipoint (P2MP)
network architecture. A PON network consists of three parts: optical
line terminal (OLT), optical distribution network (ODN), and optical
network units (ONUs). A PON network uses optical fibers for data
transmission, supports more users with less optical fiber resources, and
provides a higher access rate.
Mainstream PON technologies include broadband passive optical
network (BPON), Ethernet passive optical network (EPON), and gigabit
passive optical network (GPON).
Optical
distribution
network (ODN)
The ODN is composed of passive optical components, such as optical
fibers and one or more passive optical splitters. The ODN provides
highly reliable optical channels between the OLT and ONUs.
Optical line
terminal (OLT)
The OLT is an aggregation device located at the central office (CO),
which terminates PON protocols. OLTs in this document are MA5600T/
MA5603T/MA5608T.
Optical splitter
A passive component, which allocates optical power to multiple ONUs
connected to one feeder fiber. In a GPON network that consists of an
OLT, ONUs, optical splitters, and optical fibers, the optical fiber
connected to the OLT uses an optical splitter to connect to multiple
ONUs. The number of ONUs that can be connected to the optical fiber
is determined based on the split ratio.
