Service Requirements
A gigabit-capable passive optical network (GPON) should be capable of delivering triple play
service over Category 5 cables or twisted pairs. Service requirements are described as follows:
l Sharing of Internet access among multiple computers in the household
l Access of multiple phones in the household
l Internet Protocol (IPTV) services (program preview or watch) enabled by set-top boxes
(STB)
l Independent provisioning of Internet access, voice, and IPTV services
l Ensured service security:
– Internet access services protected against unauthorized access, hijacking or
unauthorized borrowing of user accounts, MAC/IP spoofing, and malicious attack
– Voice and IPTV services protected against MAC/IP spoofing, malicious attack, and
traffic flooding attack
l Easy fault location and service maintenance
Application Scenario
As shown in Figure 11-7, a GPON optical line terminal (OLT) is deployed at the central office
(CO), where services are converged into the metropolitan area network. An optical network unit
(ONU) is deployed in the building corridor or the curb (fiber distribution terminal). Service
access ports are provided by the local area network (LAN) or the home gateway (HGW) of an
x digital subscriber line (xDSL) upstream.
l An HGW sends services upstream to an ONU through ETH or xDSL ports, and provides
Internet services for downstream subscribers through fast Ethernet (FE) ports or WiFi, and
IPTV services through FE ports.
l The HGW has Layer 3 functions (such as PPPoE dialup and NAT), which enable multiple
PCs of a family to access the Internet at the same time (NAT is short for network address
translation).
l Set-top boxes (STB) are connected to HGWs to provide IPTV services (program preview
and watch).
l The integrated access device (IAD) in an ONU provides at least one plain old telephone
service (POTS) interface, which allows for access of multiple phones in the household.
The ONUs used in this application scenario include MA5822, MA5616, MA5622A, MA5603T,
MA5612.
l LAN ports are available on MA5616, MA5822, MA5612.
l xDSL ports are available on MA5616, MA5622A, MA5603T.
