For Ethernet services to fully deliver on the promise of lower costs and higher reliability, remote management of the network becomes essential—especially as subscriber numbers increase. Remote isolation of troubles and performance monitoring are minimum requirements for carrier-class Ethernet service.
“Ethernet Passive Optical Network” (hereafter called “EPON Network”)
comprises an Optical Line Terminal (OLT) system using its individual OLT to
interconnect with one or more specific groups of Optical Network Units (ONUs)
via a corresponding number of Passive Optical Distribution Networks (ODNs) to
construct a broadband point-to-multipoint access network between central office
and customer premises. A Service Provider can provide the broadband triple
play services by way of the EPON Network, such as high-speed Internet access,
VoIP and IPTV services.
