PON is the latest generations of access network technology. IEEE802.3ah is the standard protocol of EPON. ITU-T G.984 is the standard protocol of GPON. PON offers efficient packaging of user traffic, with frame segmentation allowing higher quality of service (QOS) for delay-sensitive voice and video communications traffic. GPON/EPON enables Fiber To The Home (FTTH) deployments economically resulting to accelerated growth worldwide.
Sopto’s PON portfolio delivers high-speed voice, data and video services to both residential and business subscribers. The platform, comprising both optical line terminal (OLT) and optical network unit (ONU), represents a high-speed FTTX solution and an alternative or adjunct to XDSL access, service provoking.
OLT of local side (Machine room) is the core of PON system, provides uplink interfaces with high speed for information accessing like voice, data, and PON interfaces for passive optical distribution network. OLT is also the control center of PON system, by which network management system can accomplish operations, management and maintenance of PON system.

ONU of user side provides interface for services like data, internet video, CATV and VOIP, wifi. By applying Ethernet, GEM protocol and so on, to implement transparent transmission of user data in PON system.
