Home gateway
(HGW or HG)
A gateway device positioned for small office and home office (SOHO)
users. It provides multiple service ports, such as POTS and LAN,
wireless local area network (WLAN), or xDSL ports. The HGW
supports routing and remote management and diagnosis.
VoD
A technology that enables users to order any program in a VoD program
library. During program playing, users can perform operations, such as
pause, fast forward, fast rewind, and program locating.
Multicast
Is also called broadband TV (BTV), which is similar to traditional cable
TV (CATV) or satellite TV. The user experience in watching a multicast
program is the same as that in watching a traditional TV program. Unlike
the traditional TV, the IPTV system encodes audio signals and sends
them to user terminals through an IP network.

Description
PON
A network that uses the point-to-multipoint (P2MP) network
architecture. A PON network consists of an optical line terminal (OLT),
an optical distribution network (ODN), and optical network units
(ONUs). It uses optical fibers to transmit data, supports more users with
less optical fibers, and provides high access rates.
ODN
A network that consists of optical fibers and passive optical components,
such as one or more optical dividers. The ODN network provides highly
reliable optical paths to connect ONUs to an OLT.
OLT
An aggregation device located at a central office (CO), which terminates
PON protocols. In this document. OLTs are MA5600T/MA5603T/
MA5608Ts.
Optical network
terminal (ONT)
A user terminal that provides various ports for users. In PON
networking, the PON board of an OLT communicates with an ONT
through the intermediate ODN network. In point-to-point (P2P)
networking, an OLT communicates with an ONT through a P2P
Ethernet optical access board.
Split ratio
A ratio used for dividing a downstream optical signal into sub-signals
in the PON system. A greater split ratio will result in a high optical power
for signal transmission over the same physical distance.
Fiber to the home
(FTTH)
A type of network that provides high bandwidths for home users. In
PON networking, an OLT connects to ONTs through an ODN network
and the ONTs connect to home users. In P2P networking, an OLT
connects to ONTs and the ONTs connect to home users. The OLT
provides voice, Internet access, and IPTV services for home users.
